SA80/L85: Why Didn't Enfield Just Scale Down The EM-2 Instead Of Bullpupping The AR-18?

[@TheArmourersBench]

As Her Majesty's government was stingey enough to essentially undercut Sterling on the SMG they were highly unlikely to contract them for the AR18, no matter how much sense it would have made haha. Good video mate, wrote my MA thesis on the EM2, you make some excellent points regarding the engineering.

[@TheArmourersBench]

@Bertie Bollocks Yeah, MA, as it was a military history focused Masters. I looked at the political wrangling behind it too.

[@BlokeontheRange]

Oh, the bad blood with Sterling was massive. "Undercut" is putting it nicely - they ripped them off, refused to pay them anything for the design until forced to by the Courts. It seems that Enfield never forgave Sterling for not taking it lying down...

[@stewbacca117]

One of the reasons I have so much vitriol for the L85/SA80 series is not just because of the practical realities of how badly the thing worked when it was first developed and basically all the way up until HK fixed most of the issues with it, but just how it represents all the worst parts of British engineering culture and procurement internal politics... - stubborn nationalism in the face of reality (bought the great Belgian right arm of the free world like everyone else before it, and most others bought the AUG or G36C elsewhere) but no, gotta make our own even though we didn't have much of the industry left/it was in the process of being sold off. - lack of direct required specialist knowledge / excess of hubris in understanding the challenge - Ala Ian's video series where a bunch of aero engineers who changed around relentlessly during the project didn't have the right background to get it done right. - design by committee round robin changes ad nauseum focusing on bells and whistles all the time instead of ensuring proper function as a core goal first. - bad business ethics with relation to Armalite and Sterling and basically exacerbating things with the people who would have been in the best position to help - corner cutting to save cost ad nauseum because lowest bidder govt reasons for something people's lives will depend on. There are probably more things I'm forgetting, but that's basically all the worst and most aggravating aspects of my own career personified in one heavy cut and shut unfit for purpose rifle... 🤔🤣 See also; The Pentagon Wars 🤔🙄 I remember when they trained me on the L86A1 and were like 'don't forget to tap the charging handle forward to make sure the bolt went all the way into battery' to which I replied "made with pride in the UK?"

Persons using the "just reverse engineer it" argument have not tried to dimension items. The tools used to dimension the part have tolerances, on parts with tolerances. And, you have little control over whether those tolerances are additive or subtractive. The Data Package you buy with a license includes things like fixture measurement jigs, that are used to calibrate the QC gauges and tools. And, the AR-18 were not made with an "Enfield Inch" either.

Until I started watching "history of firearms" videos like Bloke, Forgotten Weapons, etc. I'd never given any thought to how difficult it is to reverse engineer or scale down a piece of technology. I really enjoy videos like this which explain why certain decisions were made in weapon design.

[@stewbacca117]

Awesome vid me old. As someone who worked in reverse engineering hydraulics before I escaped the UK there are usually *very* good reasons for including stupid angles or wierd expensive features. Usually to prevent explodey seal situations or parts bending or flying off spectaculalry. Even when dealing with writing about the toy gun industry in Taiwan and how airsoft guns are made and where the costs stack up it can be frustrating dealing with people devoid of an engineering background. It's all 'so easy' when you don't have to deal with/think about thebtolerancing issues, materials selection and manufacturability of them, even just getting access within enclosed spaces for welding or machining and design and manufacture of tools, jigs, CNC fixtures and programs to just get things made consistently. One of my old colleagues was at Enfield Lock and Nottingham before it closed down and we had endless discussions about the L85 program and other heavier systems he worked on as well as the same culture you heard of regarding progression and apprenticeship etc. Would love to sit down with a few steins at some point when I'm in your part of the world if it ever goes back to normal 🤔😉🍻

[@webtoedman]

Must agree. No designer or production engineer is going to incorporate unusual angles, surface finishes or dimensions outside of the preferred series unless it's necessary.

[@Kav.]

Agree'd also, I think a lot of people in manufacturing perhaps assume that something has been designed complexly or hard to make because they assume the person designing is incompetent. Rather than it being necessity.

[@mrkeogh]

I love how everyone in this debate tends to forget the Cold War. European nations went to bullpups because they were looking at a new, faster type of warfare on the battlefield: precision artillery and airstrikes before rapid, tank-led thrusts followed up by infantry delivered by APC or truck, not marching. A shorter rifle that took up less space in a cramped APC made a lot of sense, even more so when you consider troops might be wearing bulky NBC gear. Hence, most European armies in the late 1970s and 80s began transitioning away from full-length 7.62mm battle rifles like the FAL. A bullpup is a compromise that makes sense in that environment. Now that the likely conflicts we face have changed, armies are adopting weapons appropriate to them. It doesn't mean "bullpups are shit", it means warfare has changed.

[@ernestjunior3080]

I can see your point but surely there is a better design than this?

[@BlokeontheRange]

And yet we survived with SLR's in APC's for the vast majority of the Cold War, as did many others with M16's and similar. I think this is one of those theoretical things to justify "we want a bullpup"...

I wouldn't ask a car driver for detailed information on the workings of different models of engines, personally, or to tell me what types and models of car led inventors to create which other types and models of car. I used to be into military history until I realized that it was mostly flag officer-worshipping crap, as though they determine the outcome of battles/wars to the exclusion of absolutely everything else. Good weapons, good equipment, good tactics, the leadership/aptitude of junior officers, and frequent training in/with them wins wars, not some general pushing division markers around a map from his chatau command post. "Operational" success is nothing more than the aggregate success of "small", "insignificant" units.

Eye opener on mass distribution. Very true on coming up through drafting to "engineer". The very best went to night school on the way. Others came from the machine shop. Still, understanding section modulus, and materials is something you need. These days many have access to solid modeling tools but it helps to understand the fundamentals to be a good designer. To be great, one needs more of something. Not always sure of what that something is.

[@webtoedman]

Most apprenticeships allowed "day release", by the late 50s,early sixties. Apprentices would do three days per week on the factory floor,and two at the local technical college. The employer benefitted from a more qualified workforce, and the apprentices could command a higher wage when they were time served. Not a bad system,but a bit haphazard.

[@mrjockt]

Your anecdote is actually very similar to the experience I had with the L85A1, I was in the R.A.F. competing at Bisley in 1984 when an Enfield rep turned up with an example of the new SA80 “wonder weapon”, he went on about what a great improvement it was over the current L1A1 we were all used to and the American M-16, we did get to try it out and it was nice to fire, apart from the horrible feel of the trigger, luckily I had left the forces by the time it was standard issue and all its problems started to appear.

[@JonathanFergusonRoyalArmouries]

Ooh, this is relevant to my interests! Thanks Mike. To support this, I can add that at no point in development was the EM2 considered as a starting point. Not even for the bullpup layout (well, it might have been looked at, but they didn't reference it in writing). The only connection is the original designer, Hance, having worked on the EM2 originally (but did not design it), and the use of old EM2s as test-beds for the 6.25mm cartridge.

[@TheWirksworthGunroom]

There were some trials around 1970 that probably involved EM2 as I have an example of a 7mm Mk.1Z by Radway Green dated 1970.

But that's just a story unless somebody pulls a source out from somewhere. Also related to your book, is there a place to get it in the UK where I won't have to pay $50 shipping like on the headstamp publishing website?

Some comments on the non-engineer drawing office thing. It doesn't hold that the drawing office system doesn't produce fully qualified engineers; Enfield may possibly have had a particularly lousy implementation of the system, but it's pretty much how most of the aircraft companies were set up through at least WWII (and probably the rest of the defence and engineering industries as well). The Spitfire was designed by R J Mitchell, who came out of a drawing office, and not even an aircraft company drawing office (Kerr-Stuart built steam trains). Sydney Camm, who designed the Hurricane, Typhoon, Tempest, Hunter and Harrier started as an apprentice carpenter with Martinsyde, swapped to the drawing office, went to Hawker as a Senior Draughtsman and was their Chief Designer two years later. The Royal Corps of Naval Constructors (who designed almost all of the UK's warships from Victoria's reign through the '80s) did push their Constructors through an in-house degree-equivalent, but that didn't mean the drawing office staff under them weren't also capable of carrying out the complex calculations involved in things like stability, they just needed to be checked by a Constructor afterwards. Draughtsman as a career route was considerably more than just technical drawing. My father started off with an engineering apprenticeship with his local council's drawing office, by the close of his career he was a Chartered Civil Engineer (Professional Engineer in US terms), running the entire engineering department. He got there by the well-established route of engineering apprentice-drawing office-night school for HNC-night school for HND-Chartered Engineer by demonstrated competence, which is pretty much the same route Mitchell took in a different branch of engineering. (To get to CEng under the current system you need an M.Eng + experience). In my own engineering career I've worked with chemists, astrophysicists, mathematicians, and probably a whole slew of other non-engineering specialities, while the most useful of my colleagues had an HND rather than a degree, and it didn't stop us from turning out the safety-critical FBW systems for Typhoon, 777 and a bunch of others, or being rated at the highest level of engineering competence by the US government. Admittedly software engineering is probably more amenable to that than other areas of engineering, but the safety margins we worked to tended to make other safety critical engineers go pale.

[@truckerallikatuk]

Enfield had been gutted of people who knew what they were doing years before they got told to make the SA80 system... it's not a shock they screwed it up.

[@MaxwellAerialPhotography]

I know that Ian has address this sort of question alot on Forgotten Weapons, but I think that the EM-2 and it's cartridge .280 British would have actually made an appreciable difference on the battlefield and a wars outcome. If the EM-2 or FN FAL in .280 had been developed and deployed earlier, I think it could have made a difference in the Korean War, especially given the fact that the Chinese heavily relied on close in mass infiltration tactics, aka human wave attacks with extra steps. The extra fire power over Lee-Enfield rifles would be appreciable. I am not saying that EM-2/FAL would have allowed the UN to straight up win the war, but it may have given Commonwealth units and extra edge. More specifically one battle in particular comes to mind, the Battle of Kapyong, where 1 Australian and 1 Canadian battalion faced down a Chinese division during the spring retreat in 1951. The Canadians and Aussies won in the end, but took serious casualties and both almost overrun due to the Chinese actually having superior small arms fire due, mostly a crap ton of Soviet SMG's.

[@travispollett2120]

Just figured I would add another point regarding why bullpups are often heavier than standard configuration rifles is the barrel length. It seems like a lot of bullpups tend to have longer barrels as a selling point. Same overall rifle length but you get a handful of extra inches or maybe a hundred or hundred and fifty mm of extra barrel. That's a fairly significant weight increase as well; probably not as much as the extra receiver length but it does make a difference. L85A2 and the M4 are roughly the same length, L85 is slightly shorter even, but the L85 has almost 50% more barrel length so that is adding a fairly significant amount of weight to it. Roughly comparing the M16 to the M4 you have about a kilo difference in weight and lost about 140mm off the barrel and overall length. Not exactly an accurate comparison but I think it's safe to say that a bullpup might be carrying an extra kilo of barrel compared to a similar overall sized standard config rifle.

[@yop_cholo]

Ah, your trademark British rambling. :) Always a pleasure to listen to.

[@afroliciouspresents3603]

"Only 4.5 inches shorter than an M16." That is a significant difference, in handling characteristics. The cartridge is "only 6mm shorter than a .308". The .208 is a short action cartridge, to be begin with. Six mm off that makes for a very nifty little cartridge. The difference is, again, significant, in terms of weight, cost, etc etc. I can't help but feel that 6.5mm in such a short cartridge might have retained more downrange thump, if it could reliably cycle in that design.

Back around 1984 my good friend and mentor, the late Pat Walker, acquired SN#2 BSA built EM2 rifle in 7.62 NATO in a 'trade' with Major Maurice Fogwell of the Smallarms School Museum. It was missing the unity power optic sight but I modified a Red Dot scope to fit... Pat shot it a lot (as did I), it was quite a hard kicking rifle, not well suited to the heavy 7.62mm round. I studied that rifle extensively, and also had a chance to study the two examples that Interarms had at their Manchester HQ. They were beautifully built guns but obviously toolroom prototypes, to enter service they needed extensive engineering input in my opinion.... On a side note, I wonder where SN#2 is now?

Excellent and balanced presentation there.. I think the root issue with Enfield was that it had produced nothing original or of value since the 1950s and that their much vaunted expertise was simply not tested. If they had been kept producing technology demonstrators and concept weapons during the period, then the development staff would perhaps have learned something. Instead, although the factory was perfectly capable of doing repair or refurbishment, they had almost no development capability. You also need to understand that the British small arms industry was being chopped to pieces at the time as well. It became almost impossible to get export licences for military small arms (...unless you were a governement factory!) and most went to the wall. We did manage to produce a world beating sniper rifle, but this was more down to good luck than judgement.. The Enfield management were not a nice lot, and were perfectly willing to stick the knife into anyone who challenged them. They were not adverse to setting the Police and the Security Services on individuals who voiced concerns about what they were up to!

The anecdote I heard/read was that Packard engineers went to Rolls-Royce, who were busy hand-fitting Merlins. They asked what tolerances were being held to. A figure was proudly announced.

So a couple of observations for you;, Engineer James Sullivan was one of the engineers at Armalite, who was tasked with scaling down the AR10 to create the M16. Later he worked for Ruger on the Mini-14 rifle, which is actually largely made from investment cast parts, which eliminates the vast majority of machining required, as parts are cast in the desired shapes. The AR18/180 was first produced in Costa Mesa, California and then produced by Howa Machine in Japan and finally by Sterling in England. The Costa Mesa is considered, along with the Howa to be the best. The Sterling produced guns are basically junk, poor quality control and unreliable. The (continuing) disaster of the Enfield SA80 is not surprising and even the H&K rebuild and redesign, which cost more then buying new M16/M4 rifles or G36's, basically put lipstick on a pig. Since civilian riflemen are in short supply in the UK, I expect more of the same in the future, unless they simply commit to buy unmodified, proven, foreign designs. At least the Army & Police purchased Glock 17 pistols. Nathaniel F. is awesome. Thanks Mike for all that you do.

[@hailexiao2770]

> Since civilian riflemen are in short supply in the UK, I expect more of the same in the future, unless they simply commit to buy unmodified, proven, foreign designs. Gun ownership in Britain isn't that much more strict than in, say, Russia or Germany, and both countries have good gun design capabilities. Even China, which has stricter gun laws than almost any western country, can do gun design effectively. You just need a good cadre of gun designers, and where the civilian market can't support that, either export sales or government arsenal systems can.

[@tonyb1223]

I was told that 1 WFR and 1 BW carried out the field trials for the L85 A1 and ended up passing a huge list of issues back to the trials team, think the only one I saw that was fixed was the magazine release catch but the SLR was my lersonal weapon until I was posted to NI and did the conversion course. The A1 gets quite a bit of grief, some of it is deserved, some of it isnt, tbh I had more issues with the L1A1 than I ever did with the L85A1, the A2 fixed the major problems but in theory that should have been done before acceptance. I can squeeze the RG magazine issue in here as well, we were told that these were disposable magazines, then they changed their mind and we got stuck with them rather than the heavier and less flimsy ones, the RG ones were not really squaddie proof, slamming the mag home rather than placing on and pushing just damaged them, causing stoppages when you didnt need to (due to now damaging the top of the magazine).

The best thing about the EM2 wasn't the rifle, but the cartridge it fired. NATO would have been much better served if they'd adopted .280 British as their main rifle cartridge during the Cold War. The FAL, CETME, and G3 would have been much better arms with that round. Also, to your point that it would be easier to turn the AR 180 into a machined design than turn the AR-15 into a stamped design, aren't you basically just describing the BRN-180?

[@88porpoise]

It would have been better than 7.62mm NATO in service rifles, but it was no intermediate cartridge like they should have gone for. They really missed something the Soviet and Germans had figured out there. I do not know how .280 would have compared to 7.62mm out of machineguns, though. Would it have been better as a tank coaxial machinegun or firing from a fixed position?

[@jic1]

@@88porpoise Yeah, I'm not really sure why people keep insisting it's an 'intermediate' cartridge, unless your definition of intermediate is 'any cartridge less powerful than .308'. I think if it had been widely adopted, two things would have happened: 1) The older generation of cartridges would have stuck around for machine guns and sniper riles, just like 7.62x54R did in Russia. Therefore, .30-06, 8mm Mauser, and maybe even .303 would likely still be in widespread front-line military use today 2) It would still have ended up being considered overpowered for general infantry use, and would still have been replaced by .223.

@@jic1 well, intermediate is subjective like you said. Most people do just use the .308 as the basis. What would you use to define it?

[@nirfz]

Interesting topic! After watching this, and remembering Ians videos about the L85/SA80, even if the EM-2 would have been a readily usable tried design, i think the scale of messing up the endresult, would have probably been the same. As i suspect the same people would have been involved... Also i never understood why people always claim Bullpubs are so heavy. (The ones we had, including optics, were at 3.6kg empty) Due to this video i looked up the weight of the L85/SA80 and was surprised. Wiki says an empty SA80 is weightwise closer to an AUG-A1 or A2 with full mag than to an empty one. 😮 (the a3 is heavier than the A1 and A2 but still lighter than the L85/SA80)

[@scottc1857]

Now look at the weight of an m4 / m16a1. People say they're heavier because they're heavier

[@nirfz]

@@scottc1857 What i didn't know was the weight difference between the L85 and the M16. And this difference i can understand is big enough to complain about. The difference between the M16 and an AUG is there, but it's half of that and has obvious reasons. What the M16 A1 is lighter than the AUG can be mostly atributed to the thinner profile barrel and it lacking optics. -> less metal->less weight. But both weight that can be helpfull if present. The A2 Barrel was only thicker in front of the handguard which made it heavier but it still had no optics. So if you put the same barrel profile on an original length M16 and a tough set of optics on, there's not that much difference anymore. At least not enough to complain. (With the M4 of course the shorter barrel contributes to additional weight difference) But the L85 has no such "advantage" over the AUG: it doesn't feature a heavier profile or longer barrel, and both have optics. Granted the one on the L85 has a bigger magnification, but it isn't as sturdy (soldier/field use proof) as the original 1.5X swarovski.

[@GARDENER42]

Point of order on the length: The barrel is 623mm, rather than the 518mm of the L85 & the receiver longer than needed for 5.56x45. Merely reducing the barrel length to that of the L85 would bring it down to the same length (actually 1mm shorter...).

The reality is that unless you're building a 100% known quantity, there will have to be extensive testing to identify and solve issues. The perfect modern example, IMO would probably be the US Army's IVAS program, which attempts to apply the technologies around the Microsoft hololens to a military environment. The first version which used a literal modified hololens was developed and tested for the better part of a year among a mostly closed loop of infantry troops and microsoft employees basically camping in a field before the second, ruggedized and helmet-borne prototype was finalized. Thing is, that second set of prototypes was tested by a bunch of troops outside of the program recently and there were _a lot_ of little things that were identified as needing refinement. You don't get quality hardware overnight, and if you rush it out before it is ready you _will_ get a substandard product that is not reflective of its true potential.

The 3.5x (iirc) magnification "DMR" scope is a very nice optic which I liked a lot. Oh and when holding one it doesn't feel big, but it is, it's a long rifle.

[@tomunterwegs1206]

Also just casting parts and then mashine finish them where needed is or was also a thing, like bolts. As long as you mashine finish parts in contact with other parts it's completly fine. It may be heavier and look weird but if done right its cost effective and faster than mashine something from a bigger block of steel.

[@lordsummerisle87]

That is true in certain situations but again depends on the quantities involved, the part concerned, and the technological capabilities of the manufacturer. It's not a simple or cheap process to cast a dozen rifle receivers from a tough steel with no inclusions, without burning the part, and to come out ahead of forging the blank or just machining from solid. Need 1 million sling swivels on the other hand? Great, we'll have them done by October. Will that be cash or card sir?

[@moosemaimer]

Ruger in particular uses casting for a number of things, like Mini-14 receivers, but the properties of the finished part vs. forging or milling have to be taken into account during the design phase. I used to work at a casting facility that was able to crank out small parts with precision surfaces like threading cast directly into the piece, no machining required.

[@88porpoise]

Before watching the video I am going to guess: A decade plus newer design integrating developments not available to the EM-2 in the late forties. Combined with extensive use in the field and resulting refinement of the design. Plus just downscaling a rifle to a significantly smaller cartridges isn’t nearly as easy as it sounds.

[@mpetersen6]

When it comes to tolerancing features on engineering drawings I personally think CAD has made it worse for the machinist. Engineers can be just as lazy as any body else. CAD makes it too easy for the designer to simply call out the same few tolerances for everything. Especially if they are using ISO tolerancing. Also, for shops in the US unless they have ISO tolerancing handbooks it can be tough on the person producing the parts. Plus every place behind the decimal point adds a lot of cost. Often it means an extra machining operation that involves grinding. My last job before I retired I was doing inspections on machinery designed under ISO tolerances with Inch measuring tools. Having to convert everything to metric was a continual PITA. I tried talking them into just setting up everything with Excel forms that used macros to do all the calculations with automatic accept/reject.

[@putmedown625]

THIS!! Holy crap the amount of micrometer tolerances on crap I've had to lathe. btw There's a cellphone app now ISO fits. Edit... I'm mostly machining for americans, so the parts are in inches, but the tolerances are in metric because ISO is easier for them to type in.

[@Chlorate299]

As a CAD engineer myself, I agree to an extent - CAD basically allows any Tom Dick or Harry to churn out parts and drawings without really understanding what they're doing. The worst offenders will simply turn over 3D models to the machine shop and expect them to CNC them at exactly nominal dimensions - or to apply overly tight tolerances without considering what will still work. However I don't believe that CAD is responsible for shoddy engineering, it just makes shoddy engineers able to fart out parts at a rate that wouldn't be possible in the drawing board era.

Would likely have been replaced by something in 5.56mm in the 80's anyway, whatever that might have been. I suspect that the C8 adoption will be quietly expanded over time to replace L85 given that a) it's already in the system and has been for a long time, b) it's just been adopted as the standard rifle of the Paras and Marines, c) expanding this adoption likely wouldn't need a tender irrespective of whether the UK ends up subject to EU tendering laws or not, since it's a pre-existing programme, d) it's a good system and anything else that actually is better won't be that much better and is probably rather more expensive.

[@linus11vf1j]

I think a couple of things need to be clarified with engineering design from today to then. CAD design for mechanical only existed from the 1970s and onward. This means that design work before this was done on draft table, calculating rulers, and very large books of tables for calculations. If you were doing design changes today, we can literally just pick 2 points, get a straight line, and have dessault or Catia tell us it's structurally sound. Thus the idea of tooling changes is more significant back then, compared to now. Additionally, unlike today's high speed contract seeking manufacturing market. People had life long permanent jobs and positions. However, that means that employees need to be busy for the rest of their lives. 25 years of EM2 development, and they still couldn't get something decent or working after establishment of .308 and .223 (albeit, this is less time for development). I feel that there was a major mismanagment with the team to the point of dumbing down the team through complacency. Thus by the time the AR-18 bullpup idea came around. It was something fresh, new, exciting, and as well they were too rusty to do it properly. 25 years of spinning in your chair on the same project with the title structural engineer. Asks the question "what were you doing the whole time?" I believe the EM2 could have been better if like bloke said, got Sterling involved. However, Enfield would then have to actually get off their butts and do something because Sterling is cracking the whip. Rather than sap government money until retirement.

[@snowflakemelter1172]

Sterling was only making the AR18 under licence and those are now recognised as the lowest quality of all of them, the designs Sterling came up with after the SMG were laughable junk , they certainly were not a company leading the way in design or manufacturing technology.

[@linus11vf1j]

@@snowflakemelter1172 I did not know that. Good to know for the future though. However, my point about bringing Sterling in echoes what Bloke was saying about the CEO wanting to be part of the EM2 project desperately. I believe they should have been part of the EM2 project with the flapper locking system, and working with Enfield on development and production. Sterling spits out stuff with low development times and their work equally shows that. I am inferring that if Sterling had the same 25 years or more to work with Enfield on the EM2, it could be a better developed system that wasn't 60 prototypes, and a badly chopped together system. It would probably be closer to the FAMAS than a lab toy. This interpretation is also surmised from Sterling being a corporation, and thus is beholden to reasonable outputs of productivity for their employees and investors. Thus there would be more progress on it than the Government run Crown Corporation that is Enfield.

[@vorlon010]

I think I'm one of the people who thinks revisiting the EM2 design would've been better than messing about with the AR18, but my perspective is that of all of the AR18 designs I've seen the only one that seems to have been without some kind of significant problem is the armalite itself - though admittedly I think most of the problems have been political in origin, such as the SA80 itself or the G36. Also on the engineers being unable to successfully reverse-engineer a known-good design likely ballsing up the ground-up reconstruction of em-2-small, I agree, though there's a chance that putting these people in a position where they *don't* think they've got an easy job might have been enough to force them to do it properly, rather than the ballsup we got. I also think that in a lot of cases in weapon design there seems to be this idea that newer is automatically better, irrespective of the relative merits of the system itself and the relative technical maturity of it. The AR18 *is* a very technically mature design as this point, I don't think the flapper lock system is as mature and could turn out to have it's own advantages which aren't well understood currently - at least to my lay-perspective

Scaling it down to an intermediate cartridge rifle might have caused it to be too small to work and another locking system might have been more space efficient. Even today, someone out there is making a large caliber semi-auto rifle that uses two huge flaps like a DP/DShK, but that also not a small caliber rifle. Truthfully I'd be curious to know of any other flapper locked guns other than the DP-28, DShK, and the G34.

@@vorlon010 The Steyr cage-thing is something they added to stop the bolt from rotating when in travel, all AR-style bolts have some type of measure to ensure this doesn't happens, for example in AR-15 the bolt can't rotate before in reaches an area in the receiver where a space was machined(that small bulging part of the left side of the upper). Don't't take the mud test as gospel, it's a single stress test for a design and it doesn't tell the whole story about reliability, the fact that the AUG has been adopted in multiple countries, with a multitude of environments should be much better testimony about it's performance. In SCAR has alleged issues with damaging optics on the long run.

[@vorlon010]

@@ShortT-RexLikeArms You make fair points - I do still think the AUG cage thing is a significant redesign, at least compared to others in the extended AR18 family, and I shouldn't take things like the inrange mud test or random anecdotes in comments as gospel or all encompassing. It's all enough to make me *personally* wonder about the design and if there might be a better one for all these different companies to iterate one - but that's a personal speculation and I'm just some guy on the internet, not required to necessarily be right about it, if you get what I mean.

Does anyone outside of Ruger's development department know how the AC-556 has held up in French service (Mousqueton A. M. D. ) or some of the other services? Geoff Who has examined some used police semi-autos but I have no knowledge of the rifles history., training, use, etc.

I heard it was adopted because they wanted a new manufacture rifle in a modern cartridge (5.56) but still looked like an old fashioned rifle.

@@Treblaine From what I've heard, specifically they wanted a rifle that was as much like a 5.56 M1 Carbine as possible.

No, relations with Sterling were terrible, largely cos Sterling didn't take RSAF Fazakerly building their SMG and not paying license fees lying down and sued.

In my opinion we hit the last major breakthroughs in firearms design in the 50s/60s. Since then it's just been refinement. The next breakthrough will probably be something along the lines of electromagnetics, either effective Gauss Rifles or plasma rifles.

[@mpetersen6]

And that's going to require major breakthroughs in energy storage, room temperature superconductors etc. Personally I think the next development could be a reliable caseless ammo system.

[@DarthEarp]

I disagree. while most firearms today are simply more refined versions of those of the 50/60's, some are substationaly different. i'm thinking of the HK G-11, AN-94, FN P-90, and Kriss Vector.

[@Thoroughly_Wet]

@@DarthEarp g11is a 60s design. the vector and an-94 show promise but are too expensive to be used to scale. I probably should be emphasized that I meant in large scale, military use. the g11 uses caseless ammunition which can be a logistical pain to store compared to traditional metalic cartridges, as well as the fact if you get a dud round you can't extract it easily because there was no need for an extractor. Even if there was, caseless ammunition would be somewhat brittle and if it was truly stuck in there youd bust apart the propellant making it worse The vector system is a fairly promising idea but it hasn't gone anywhere beyond a pistol caliber smg/carbine in about 10 years and the military has already decided theyd rather use m4's over smg's to arm vehicle crewmen, so unless kriss steps up and makes a variant in 5.56 or the new 6.8 the army is trying to switch to, it's not gonna be picked up. I completely glazed over the p90 as that's just bottlenecked pistol calibers which we've had since the first semi-auto handgun.

[@ShortT-RexLikeArms]

@@Thoroughly_Wet You can extract an defective round from a G11, it's uses the next round in the magazine to push the round out. Very similar of how the Steyr ACR and the newer Textron design eject empty cases.

[@adamdean5881]

I would push that plateau earlier, maybe the 1910s. Semi-automatic rifles and handguns were for sale on the civilian market since the turn of the last century. Everything since has mostly been moderate improvements and refinements.
