What Would Stoner Do - In His Own Words

[@bakelitenwaffles78]

I'm the guy who uploaded the Eugene Stoner interviews to KZbin and just wanted to say I've been a long time fan of InRangeTV (this is an alt account), so it's great to see you commenting on these. The interviews themselves are great for clearing up a lot of the fuddlore around the M16, with Stoner's own words no less. I especially enjoyed Stoner's story about the project director hammering rounds into the chamber in order to justify the forward assist. There's also stuff about the Stoner 63, Stoner's later work at ARES where he takes apart the Stoner 86 LMG, and even Kalashnikov and Stoner meeting in Virginia in 1990.

Many thanks for uploading these! They deserve to be on the internet. I'd like to think that the forward assist is vestigial, but I can't shake the thought that it's useful for bolt binding in freezing weather, a la what happened frequently in winter during the Korean war. Did he comment on that in any of the interviews?

I was an Air Force SP in the 80’s. We carried M-16’s without forward assists. If something went wrong, you racked the charging handle and kept going. I never had a problem. Stoner was right, you don’t need it!

[@LRRPFco52]

USAF was the lead for taking the AR-15 to the Pentagon after Dr. Carten on Army Ordnance Board rejected it. Once the subsequent production orders kicked off with the lessons learned on the Colt 601 and Colt 602, the US Army 603 specs required the Forward Assist, while the USAF 604 forbade it from being present. USAF had 601s (Green Rifle), 602s, and 604s in service up into the 2000s.

[@larry648]

I know the timeline. I was in 84-88. I saw a mix of a lot of cool old parts still around. Duck bill and three prong flash suppressors, chrome bolt carriers, small tab bolt hold open buttons, even a few small triangle charging handles. We also had GAU-5A’s, Colt Commandos. We were short on M-203’s so we also had XM-148’s thrown into the mix. I also qualified with the M-79 as a contingency. By the time I got out all the old parts had been updated by the armory. Everything had bird cages and phosphate bolts. All the old 20 round mags were gone. We didn’t carry them, but we used them in training. I managed to keep a couple.

[@larry648]

You must be and Army guy 😀. I was on a SAC base with alert B-52s, KC-135s and a squadron of F-106s. The bombers and the fighters were loaded with “priority A resources”. We had our Sierra together and we were not playing games.

The M16A2 is everything that's wrong with the design by committee - Karl Me - I remember being in Iraq and Wishing I had something as light as my A2, when I was hauling around that pig of an A4 with heavy barrel, quad rails, and rail covers. The A2 was a downgrade.....but things got SO MUCH WORSE.

I like the A4, but thats mostly just cause of the ability to mount things to it. Now however with how they went about it as you said it was like a boat anchor

[@ragingbombast]

I hated the A4 so much. So much weight just for the ability to strap on even more weight in accessories that maybe 1% or less of the people issued them would ever actually use. And it always felt front heavy.

[@Hibernicus1968]

When I was a new recruit in the US army in 1996, waiting to start my basic training as an 11B at Ft. Benning, between my inprocessing at 30th AG, and my starting basic at C Co. 2/58, I was detailed for 3 days to the armory on the base where a lot of small arms were stored and serviced. It was mostly staffed by DOD civilians who were veterans, and the one I worked most closely with those few days was a Vietnam vet who presaged many of the same criticisms in this video. He firmly believed that the M16A2 was an inferior weapon to the A1. It might have been better on the target range, with its more finely adjustable sights, but it was not a better _combat_ rifle. The adjustable sights were a needless complexity, he said, that would go unused by most soldiers. The 3-round burst feature was an attempt at a mechanical solution to a training problem. And the heavier barrel wasn't heavier for most of its length, only out near the muzzle where you didn't want all that extra weight to be. I think he was spot on in his criticisms. It's interesting to me to consider the parallels behind the thinking that produced the M16A2, and the M1903 Springfield, which also had a rear sight optimized for target range performace, but wasn't a great combat rifle sight. It really is true that the longer a peacetime period lasts, the more the army's thinking drifts away from what works best in combat, and toward controlled events like target range competitions at Camp Perry.

For those who have a problem with a lightweight weapon, I invite you to attempt this thing called a ruck-march. Put on body armor, ammunition, a full camel-back, and a 40 pound pack.

I've got a .22 project that will likely end up around 12-14 pounds and it'll be fun to shoot, but no way am I packing it around in field or woods. Fun and games on the internet.

Doing a ruck-march in full kit including your weapon of choice before a gun match is actually a great idea.

[@metal4ever516]

So here's the thing - I love guns with steel receivers, gas pistons, and wood stocks. AK, SKS, even the M1A - love those. However, the reality is that Stoner's design and concepts work, and that in some respects, particularly weight and portability, the Stoner ARs are an extremely good idea for a lightweight fighting rifle. And they've been proven. If an AK guy like myself can see the logic to this design and the materials used, I would hope others could as well.

[@thepinkplushie]

Hell, Kalashnikov saw the logic too. All their modern designs have moved on from wood, and have modernized in general (though I gotta say, the most recent generation is disappointing. Seems to be tacking on more and more "tacticool" crap rather than focusing on lightening and flexibility for deployment. Probably why the majority of the Russian armed forces and its allies are still just using AK-74Ms. Kinda a high point in AK design).

[@genericpersonx333]

The weak point of Stoner is dependence on high-technology and chemistry that is not universal or even widely available, especially in the 1960s. The USA was one of the only countries with enough polymer and aluminum-working infrastructure to even attempt the Armalite rifle concept. Today, with the sheer economy of scale involved, people forget how complex the actual manufacturing of AR15 components is; InRange has plenty of content showing such. Stoner could look forward to an expanding chemical industry and more use of aluminum, to continued innovation and lowering costs, while today, we have to be aware that society, or at least politicians, may decide those industries are not acceptable to them. All it takes for key polymers to stop being available is someone getting 400-something votes in Congress saying that polymers as they are are too environmentally dangerous to continue as they are.

[@thepinkplushie]

@@genericpersonx333 oh, my friend, the arms industry is a bigger priority for the majority of politicians than the environment will ever be. AWB and shit like that is one type of thing, focused on disarming the public, but almost no one has any interest in disarming the military, or forcing them to fundamentally change. And the arms industry are great friends to have as a politician. They can pay for your entire professional career. Republican, democrat, doesn't matter. (Also, as someone who is very environmentally focused, while the US military is one of the biggest polluters on earth, AR-15 materials are not a notable contributor, especially because AR-15s last a very long time, and the materials they use being expensive actually incentivizes industry making them to reduce waste as much as possible on their designs (since wasting special polymers and such). Trying to be pragmatic here and put my thoughts on military and state aside, purely looking at contributors to climate change, the USAF and US Navy are places to look first, as well as ridiculously inefficient vehicles like the Abrams that just guzzle high octane fuel at a comical rate, for minimal benefit)

They thought it was necessary because the AR was the first rifle that didn’t have a charging handle that was connected directly to the BCG.

Chroming the bore and chamber instead of the bolt and carrier seems like a tradition worth preserving, in all honesty

[@militantfascade9176]

@@TheSundayShooter I think if you want to chrome an AR type rifle, BOTH is the way to go. The gasses come back into the bolt carrier through the gas tube, then expand in a chamber in the carrier and press against the bolt to unlock. The chamber, the barrel, the carrier, and the bolt head all get exposed to any corrosives from firing in that order, with the exception of gas leakage around the casing. Just chroming the barrel and chamber ignores the corrosion in the carrier and on the bolt, which also affects reliability, durability, and longevity. The same goes for the opposite: if you chrome the bolt and carrier but not the barrel or chamber, you'll have higher risk of corroding or prematurely wearing any surface inside the chamber or barrel, including the edges of the gas port, where the gasses under pressure erode the steel.

The first AR-15 furniture was a series of phenolic resins that eventually evolved into glass nylon with the last M16A1 furniture updates in the 1970s. The earliest furniture on 601s was brown like Bakelite, then started getting black dye added on the 602 and early mottled looking stocks, grips, and handguards in the no-compartment buttstock days. M16A2 took the glass nylon from the last A1 upgrades and beefed it up in thickness, while introducing the mirrored circular handguards. Early triangle handguards had a tendency to crack teeth, so that specific left or right HG would need replacement. Circular guards reduced the logistics burden of triangle L-R guards, with an increased strength material and design where no teeth existed. The buttstock was lengthened too, which made the A2 a bit unwieldy for about half of the soldiers. The heavy forend profile on the barrel added weight in a place that threw the balance off. The original AR-15 & M16/M16A1 handled much better for carry and presentation.

Coming from a combat Marine perspective, I have used the forward assist in a literal firefight in Afghanistan.

Had I needed to take my rifle apart in the middle of a firefight, I might not be here today or someone else may not be here because I would not have been able to maintain suppressive fire. Just my take, but it's not the 100,000 non-failures that justify an addition; it's the one failure that can cost lives that justifies it.

[@5jjt]

I've seen a forward assist actually come in handy once. I'll add that the bolt has to rotate, creating friction, while it's force for closing often depends on how the charging handle was released. If released to slowly or awkwardly, a forward assist can come in handy. This is referring to, of course, loading a new round from the mag manually. Further, there can be extraction issues resulting in a bolt that doesn't travel rearward all the way, thus creating a weaker than desired new feeding. And, this is also where a forward assist could help.

[@nla27]

One reason I've used the forward assist. SNOW. If you shoot in the winter and get any moisture in the rifle, the bolt can bind.

I like having a way to strongly manipulate the bolt in both directions.

Really just depends on how things are jammed in there.

I think the fundamental assumptions of the WWSD project is that in post-war America we COULD design and build rifles using aircraft engineering.

[@MandoWookie]

What I find interesting, is that the US military knew all the way back in the 20's that smaller calibers had better wounding capability than larger calibers at practical ranges. According to Julian Hatchers Book of the Garand, they did tests with calibers from .25 to .30, and found that out to 200yds, the much higher velocity of the .25 did noticeably more tissue damage than the higher calibers. They even noted that with better projectiles they could probably push that out to 300 to 400 yds. But past that the larger calibers retained better penetration and range, and because the military was committed to one standard cartridge for both rifles and MGs, and didnt want to lose the long range ballistics in the MGs, they compromised on .276. Until Garand showed he could make 30'06 work in his rifle, then they just stayed with that. But there had been a vocal contingent in the Ordnance branch (Hatcher among them) to adopt what was essentially the assault rifle concept back in the 20s, based on these and other studies.

[@fryingpancakes8445]

It's funny how there is this stereotype about Russians being brutes with their weapons and smash their guns to fix any malfunctions. And yet the US military literally asked Stoner to add a feature on their gun so that they can do exactly that

[@mochaholic3039]

@Sauli Luolajan-Mikkola I dunno, the Singaporean troopers I talk to, they like the forward assistance in their ARs-- the guy I talked to described in an mock battle where they laid an ambush; due Singaporean military rifle handling procedures they never have a round chambered until it's time to actually engage the enemy and when the guy's troop was ordered to charge their rifles, they'd pull the charging handle back just enough to get a round into the chamber but not far enough to engage then they'd use the forward assist to quietly seal the bolt instead of the regular noisy chambering process and potentially alert the OPFOR.

[@n4d3m4n]

I've used my forward assist now once to fix a jam! Spent case got stuck in the chamber after roughly 50 rounds. I used the forward assist to push the bolt over the cartage so the extractor could grab it and then mortared the brass out of the chamber. It worked once! I've never had to use it before or since in roughly 5000+ rounds that I've shot through ARs.

Barrel length. Stoner mentioned the importance of velocity for .223 Rem multiple times in the clips you showed.

Continued improvement in propellants permit attaining the needed velocity with a shorter barrel. Added velocity would be gained, but the necessary velocity is achieved with a 16 inch barrel.

[@Verdha603]

Another thing not mentioned is the gas system; to my recollection the WWSD rifles use a mid-length gas system, which is considered better than a carbine-length gas system (commonly found on the M4 carbine) due to applying less pressure on the BCG when gas is vented, reducing long term wear and tear. The reduction in barrel length also doesn’t greatly affect the performance of the rifle at typical shooting distances (0-300 meters). A 20 inch barrel really starts to provide noticeable performance gain once you start shooting past 300 meters.

I used to be of the opinion the forward assist had no legitimate use but I have changed my opinion. Field conditions over the course of weeks in hot sandy areas will slow a rifle down. Maintenance for sure helps but when you have been crammed in the back of a Stryker with a section of dudes and you can barely move your arm with all the gear required to be in there let alone dissemble and clean your rifle proper maintenance will get stalled. Putting heavy amounts of sand and dirt into/on a gun will stop it, pounding a forward assist wont do anything but make it worse. However, slow accumulation in shitty conditions will slow the whole rifle down and the weapon wont always have the oompf to close the bolt. In these kind of field conditions, not some test to simulate conditions will you learn how your weapon truly works. I have used the forward assist in these conditions enough that I feel it should be a legitimate part on any combat rifle.

What a learned in the Army was the forward assist is used when you need to load the rifle in silence because if you load very slowly, without making noise, the bolt wont lock without make a push with the assist buton. In 5 years in service I probably used a couple of times. Just curiosity.

I'm a Marine since 2007 and although we trained with the forward assist, I never had to use it not once. Now civilian side my first AR was the M&P15 Sport Gen1 I got in 2011 and it has no forward assist or dust cover; it has been in the deserts of Arizona to the snowy mountains of Idaho to the coast of Oregon and it has been doing fine. I'm in West Virginia now and it's holding up to environments I go out with it in. All I replaced so far in it is add a stock saddle, Magpul MOE handguard and pistol grip, and added a Springco heavy buffer spring. Everything else is stock aside from replacing the gas rings and the cam pin on once a couple years ago. So fun.

The only time I have to use my forward assist is when I baby the carrier home. Never in a firing situation, though.

[@MCXL1140]

A properly set up and tune AR-15 the bolt should never get stuck even if you really slowly baby the carrier home. If it does not go into battery when riding the charging handle forward your gun is not properly tuned or is dirty and fouled.

[@thepinkplushie]

@@chickenfishhybrid44 the counterargument is that while there's some issues where forcing the bolt into battery is the solution, there's many more where that isn't, and there's a few where that will make things significantly worse. While the forward assist has theoretical uses, what it actually acts as is a massive glowing neon sign saying "HIT ME" when anything goes wrong, whereas the best bet is usually to open the bolt and look for obstructions or fouling. And sure, in combat this is difficult, but while there may be one hypothetical scenario where hitting the forward assist saves a soldier's life, I can think of one just as likely where hitting the forward assist exacerbates the problem, and now you've got a bricked rifle in an emergency. You could argue it's an issue of training but it's just human instinct to click the "might fix it" button in the heat of the moment, rather than going through the steps to actually assess the issue.

I agree with your position on the forward assist, what gets forgotten is that it was an 'oh, shit!" button for a rare, "oh, shit!" situation which was being face to face with the enemy and needing that one round to go, no matter what with a carboned up/dirty chamber not letting that round fully sear into battery. Any "properly maintained" rifle with properly made ammo shouldn't need a button. I fully understand all the bad stuff involved and that you're probably not going to get a second round working after actually having to use the button but, when you've got an eighteen yr old kid with a dirty rifle faced with either dying for sure or pushing "the button" and possibly living, they installed the button. I get it.

[@tangero3462]

Nothing stomps out myths like cold hard fact The only changes that needed to happen to the original Colt were the mag release fence, the new ejection port cover, the empty case deflector, and the A2 compensator. The clamshell handguard replacing the triangle is also sensible, as it is both more comfortable and easier logistically. Perhaps the rear sight could have been redesigned as a 4-position rotary flip like the CETME instead of a 2 position just to accommodate a little extra potential range with the rifle. Perhaps 300m ghost ring, 300m fine, 400m fine, and 500m fine apertures could have been the configuration (maybe 450 and 600), though the original design is more than serviceable.

[@thepinkplushie]

All good points, though I'd say the sight changes are by far the least important for the average grunt. If you're firing at those kind of ranges you'd hope you'd have enough time to adjust your aim by eye, regardless of sights. And at that range suppression becomes more important than trying to get precise hits on target. Then again, I suppose 500 should be accounted for as it is on the higher end of what I'd consider "practical" range for a standard rifle, so I sorta see where you're coming from. I just worry cause I see a lot of rifles trying to account for various ranges and it often degrades the quality of the sight itself. Looking at pictures of the CETME rearsight, it looks mediocre, though obviously I'd have to fire it to know for sure.

[@tangero3462]

@@thepinkplushie they're functional at best. The general gist was all I was getting at, not simply grafting one onto another.

I have a question: how does the stoner 63 factor in the convrsation? Do you think that some elements from THAT project could be transferred to the WWSD2020? Or do you think that the two projects are ultimately too different from each other to meet each other in any significant way?

[@JanTuts]

Yeah, the way I see it, the design goals / constraints were simply completely different. The goal of the original Stoner M69W wasn't "a light-weight carbine" like the AR-15, but something that could basically handle every small arms role, including sustained fire in the belt-fed machine gun configuration. And so it was initially designed in 7.62x51 NATO, because militaries at the time would definitely want their (L)MGs in that caliber. And as a result, it was also designed to be very robust. But then lo and behold, by the time it became the actually commercially available Stoner 63, Stoner and co had changed it to 5.56x45 NATO (also making it one of the first 5.56 belt-fed MGs), and gave it a plastic stock and grips (i.e. lightening it where possible). What really hammers it home is, when you look up what he then did later on in the LMG space with the Stoner 86 and 96, it all reads "light-weight LMG", "weight reduction", etc etc

Spend weight where it is needed and remove it where it isn't. #2, My favorite: If you want light weight you just need to hit the gym more, hurr durr durr! Uhh, given equal gym time, every UNNESSCESSARY ounce removed is an ounce of something else I can carry, like a few more rounds, an extra battery, extra anything. Esspcially as those replacement items can be carried on the body and not the rifle, it is a big advantage.

In the Army when we were trained on remedial action, the acronym we were taught is SPORTS - slap, pull, observe, release, tap, shoot. The "tap" in that was smacking that forward assist a couple of times. So it certainly was part of training. I will say I never had a need for it. The only time I ever used it is if I did a press check, I always felt better tapping it after because in my brain it might not have gone all the way back into battery.

[@drownthepoor]

The talk of the forward-assist is kind of interesting. If you need it you have a problem that needs to be fixed, not a workaround right? Well in combat you do not have the time to troubleshoot and fix a rifle when trying to get a round off. If the assist can get you one bullet into a combatant it did it's job. Removing it is insanity in my opinion. I've used my forward assist once, and then fired hundreds of shots and never had another failure to chamber so the underlying problem was an anomaly, and the forward assist was the solution.

Im still curious weather Stoner prefers the 556 over 308, like u say, its true he basically designed the 223-556, but he only did so to meet the military specs, not HIS specs.

[@colemanmoore9871]

He spoke about the weight reduction, recoil reduction, and the nearly identical effect on target at normal combat distances. If he still preferred the .308 after that, then he was an idiot. And we know he wasn't an idiot, so I believe he preferred 556 in the standard combat rifle. But it is about the right tool for the job. When shooting further, or shooting at concealed or hardened targets, then you need the bigger hammer. Hence, the DMR he designed was in .308.

[@DonMeaker]

One must, with caution, note that there has been significant learning since the 1950s, and that leads to heavier weight 5.56mm bullets, modern propellant that gives good velocity from a shorter barrel, and enables the other improvements from Stoner's contemporary design. That learning also took place in other countries, leading to widespread deployment of body armor, night vision devices, and silencers, which affect the environment in which a modern rifle would be used.

[@brawlnoob7791]

I think I would keep the aluminum lower receiver just for the sturdiness. The rest of it fully agree.

[@frankholub4673]

At least as far as I've seen, you haven't really talked much about the gas system when discussing the WWSD project, was that ever a consideration when figuring out which barrel, gas system length, gas port size, and gas block to choose? Faxon barrels, at least in my experience, are significantly overgassed with a 16" midlength gas barrel having a whopping 0.081 sized gas port as per the manufacturer. That thing would fling cases almost straight forward, and bottom the buffer out harder than necessary. Swapping the upper to a 16" midlength gas (0.076 port size) completely changed the ejection pattern to 3-4:00 with the same ammo and the same lower/buffer setup.

[@phillycheese2542]

I think the main reason for the oversized gas port is that people don't fire the same ammo. With a military adopted rifle, you know exactly what ammo is being fed into the rifle and you have a defined pressure range at the gas port, so the port size can be tuned for optimum function. With a commercial barrel, you have zero control over what goes into the gun, so you have have to size the gas port to function with the shittiest ammo on the market, otherwise you have people complaining that their guns don't work when they feed it Tula .223 and posting on forums and stuff that your gun is a piece of garbage when it's really their ammo that's garbage.

[@tangero3462]

I haven't measured the port but my experience mirrors yours. On a WWSD-esque build, a Faxon pencil mid length was ridiculously overgassed; ejection was like 1 o'clock with the basic carbine buffer shipped with the KP15 (also, really guys? Spend five bucks more on an H1), barely any less with a Geissele Super 42 and H2. I had to put an H3 in the damn thing to get it running right, which really should only be reserved for suppressed guns and rather worn barrels. It's making a product for the lowest end of the bell curve, ignoring that the vast majority of people buying a not inexpensive component won't be running the weakest possible ammo through it.

[@frankholub4673]

@@phillycheese2542 I definitely agree that the reasons you stated are the reasons why so many manufacturers overgas their rifles, but it's not a compelling argument imo. Colt builds 16" midlength gas barrels with a 0.071 port and Daniel Defense builds their 16" midlength gas barrels with 0.072 ports. Neither suffer reliability issues on commercial ammo. That's a whopping 0.009-0.010 smaller port size than a Faxon. For a different gas system length example, Geissele builds their 10.5" barrels with 0.068 ports, which is 0.002 smaller even than Crane spec, yet they're very reliable. An AR doesn't need to be overgassed to be reliable, it needs to be properly gassed. Otherwise people have to resort to messing with buffer weights and adjustable gas blocks just to make their rifle function as intended without beating itself to death due to premature parts wear.

[@Full_Otto_Bismarck]

@@lucastonoli3256 Yeah i have no interest in a full stock either as the length of pull is always too long for my taste and body armor can affect the length of pull needed as well.

[@DrewishAF]

I don't usually bring it up because it's a bit of an esoteric point, but the AR-15 is really more of a hybrid between DI and piston gas system. From the chamber, the gas goes down the barrel and a bit is tapped off to the gas block. The gas then moves rearward towards the carrier by way of the gas tube and the gas key (bolted and staked onto the carrier.) That is a DI system. But at the carrier, the gas gives the carrier a rearward push via the key. Then, the carrier unlocks by twisting the bolt. The bolt has 3 piston rings at the back which helps keep the system sealed until the bolt twists 45° to unlock. The gas is then able to exit the side of the carrier by the ejection port through a couple holes on the carrier. The system then cycles from rearward into battery to be fired again. That part is actually much more built like a piston system. In a normal DI system, the gas presses directly into the breech block and there's no pressurized, sealed system once the gas forces the bolt/block back. In a gas piston system, the gas pushes against a piston (a larger surface area requiring more gas at a lower velocity) which then is either attached directly to, or impinges on by a separate component on an "engagement surface," the breech block/bolt. And no, it doesn't particularly matter how you would classify the specific system in the AR-15 platform because it works great. All of the different designs for cycling systems in firearms are going to have variances between how they work. Nothing is going to fit directly into a category unless the category is made specifically to describe it. This is more of an abstract consideration on the matter because THIS is the channel where those abstract/esoteric matters have a bit more value.

In any system using gas pressure, there is ALWAYS something acting as a piston and something acting as a gas cylinder, whether in "conventional" DI, Stoner-type DI, or even direct blowback (the cartridge case itself acts as the piston). This hair-splitting as to whether the Stoner system is DI irks me somewhat - gas is injected into the bolt carrier, it's just handled in a more clever way than simply making the gas cylinder part of the carrier like in an AG42, or one of the French systems.

When I started looking at parts for my first AR build in late 2019- early 2020 and the wwsd Playlist really helped and made me really appreciate the ar15 design thank you.

Great video! However, I disagree about forward assists. Although they weren't originally supposed to be there, I like them. I've never had a problem chambering around if I pulled the charging handle all the way to the rear and let it go, but if I decide to let the bolt close slowly the bolt doesn't always close. That's when I use it. Primarily for hunting when I'm trying to be more quiet or for press checks and such. Besides I wouldn't want to just push on the bolt that may or may not be hot from shooting. If the gun had a charging handle that could be used to close the bolt, then it wouldn't matter.

[@speedindeemin]

That’s a good point, giving it a different use than originally intended. I can see how that would really help keep the noise down. Doesn’t matter if the bolt is slammed into battery, or walked in slowly and pressing the button. Locked is locked, it’s g2g

@Sauli Luolajan-Mikkola multiple uses... Read it again.

[@CQCMachine]

@Sauli Luolajan-Mikkola you're still not getting it. Multiple situations. Multiple uses. Figure it out.

[@stevegee218]

Diemaco also had some good ideas when making what would become the C7 rifle and pushed design ideas of the time.

[@michaelmorgan5734]

In regards to the forward assist I’ve been hunting and I don’t like to drive around with one in the chamber (in case I get pulled over by a game warden it looks better on me) so when I get out of my truck and chamber a round I have on a few occasions not slung my charging handle hard enough trying to be quiet. I always check and see if it gets sent home all the way and a couple of times it hasn’t, a good love tap with the forward assist sends it all the way and I have killed deer relying on it.

"We're soldiers, damn it. We need something to pound on to close our bolt." Military intelligence at it's finest.

@@RolandtheThompsonGunner yeah.... look at some old french rifles... they had a bayonet lock on them that was fashioned in such a way that you could use the bayonet lock to interlock two rifles together and be unable to seperate them....

Gene is a badass!!! I have been able to learn how the rifle was built and it’s final iterations to what we have now from plenty of information on Stoner but also from military guys as well. One of the best publications I have in my collection to date is a book written by David R. Hughes, “The history and development of the M16 rifle and it cartridge.” Mr. Hughes makes a point that the M16, while revolutionary, was a fresh mix of designs from other guns that had already been in production… for instance, the M16 embodied the following characteristics: 1. Hinged like a double barrel shotgun 2. Easy bolt removal and inspection like the European FN rifle or the Czech ZH 29 3. Bolt locking system like the Johnson Semi Auto of the 1940s. 4. Straight, in-line stock like the Harvey T-25 5. Integrated rear sight and carry handle like the British EM2 6. Hinged ejection port to keep out dirt and water like the German STG 44 7. A gas tube system that operates without a piston and op rod similar to the Swedish M42 and Ljungman rifle. Stoner originally designed the AR in 30 cal because Armalite knew the military wanted to stay with the large caliber round. Although the Army started the “Small Caliber High Velocity” program, they eventually ran out of money and had to stay with the 30 cal round without finishing testing on the small caliber program. Gene was the pioneer of the Rifle and there were many more people that we don’t speak of that helped develop the rifle from Colt and the Military! From what I have learned about the forward assist…. It’s number one benefit was quietly aiding in removing water from chambers and allowing soldiers to get the bolt locked back up in the Vietnam climate. Whether in water or the field. I don’t think Stoner anticipated that. That’s probably why he though it was useless. But his paycheck was coming from the military so we have forward assists!
