It's amazing how much information I get from your channel. I have been learning everything I could about firearms for 25 years and I thought I knew a lot. I've read a tremendous amount about guns, and I own many guns, but I still learn so much from your videos. I hope you don't stop anytime soon.

Thank you PJ Nelson - I'll keep going : )

I finally know what the straight pull attachment in battlefield does. Thank you

[@stefanschug5490]

Heym rifles were always one of my favorites for hunting wild boars in Germany. I used to hunt with a SR 20 but the concept of the SR 30 which is still in production is fantastic. One point though is that with the recoiling rounds usually used for wild boar hunting any advantage you get from the straight pull actions is minimal. Especially for fast running pigs it matters more that you have a well fitted stock and lots and lots of practice with your rifle to make that first shot count.

[@user-gd7fx4jf5c]

Blaser, Mauser, Sauer, Merkel and Steyr are definitely great companies with amazing Rifle’s ⚡️

[@theronnelson3704]

The petals you are referring to, and indeed the whole part, is inspired by a standard machining piece called a collet, specifically an R8 collet. Still a genius move on the part of the designers, as collets have been around for almost a century, since the introduction of the Bridgeport milling machine. Therefore they are proven designs for reliability and accuracy of movement. The term you were searching for is called the "collar" of the collet.

[@maverickpaladin4155]

That Blaser system looks to be essentially a modification on the flapper lock system as used on, among others, the Degtyarev machine gun designs. The same basic idea was employed by CETME and later HK in their roller lock designs. My guess is that these straight pull rifles by Blaser and Heym took that basic concept and made the system radial instead of horizontally opposed. These are really cool designs. It's a shame that more companies don't employ them.

[@diegofianza3525]

Amazing analysis. I’ve been searching for a straight bolt design to apply to a slide action. I’m glad someone is looking for the same.

Speaking of German guns, the ball bearing lug design on the Heym, is similar to the HK41/G3/91 or their sporter versions 770 etc. all with semi-auto bolts. The HK design is "old school" now but genius...solid, but in the instance of Heym, the lock up is bolt handle actuated instead of cartridge pressure. Thanks for sharing about these amazing and beautiful machines!

Mike, those are much like what we call in aviation, “expandable pins”. Which have been used in many forms to lock in and attach things from gearbox mounts to helicopter rotor blades and I’m sure in many other forms, although this a different orientation and application of a similar theory of course.

I'm currently looking at a SR30 as well (in 8x57IS), what I found especially pleasing about the Heym is that it's affordable (I'm Dutch after all)... Around 2,000 euros depending on which options you select in their configurator. That's a bargain.

[@normanmallory2055]

I have always wondered how that action locked up, great close up view of the lug pedals in action... Some years back Colt came out with the Colt Sauer bolt action which had 3 large pedals that locked into the action, it's one of the slickest actions i have ever handled ... Oh around 1980's to early 1990's Colt brought that action out.... I have not seen one for years now where i live and shoot..

[@martinstiastny7679]

Colt just marketed the rifle in America. That rifle is pure German. Sauer designed it and sold it as a Sauer product; the model 90. Of note, the Colt Sauer rifles all have glossy stocks like Weatherby rifles. The Sauer model 90 is mostly found with an oil finished stock. The Sauer model 90 was discontinued in 2006 or so, but you can find them on Gun Broker and Guns America.

[@karldegroot3131]

Cool. Looks like an R8 machine collet (operating in reverse) and actuated by mechanics similarly found in a ball-lok pin.

[@kamelthorn]

Nice review. The flaring lock system is very strong as the ballistic forces are distributed throughout the lock surface within the barrel, and not as rotating lock where the forces are distributed on 2 or 3 points within the locking mechanism.

[@UnitedStatesOfGuns]

Thank you and I agree - the R8 and R93 are amazing and absolutely strong. I just ordered a another barrel for my R8 - I find myself liking the R8 more and more.

The ball bearing locking mechanism is a logical extrapolation of the old CETME delayed roller locking system. Maral is a large central asian deer; wapiti plus in size. There is another popular straight pull rifle made in Cologne (Köln), called the Steel Action, which has been around for about 3 years.

There is also the Lynx from finland which is almost a heym sr30 but with steelbars instead of ballbearings.

love how you said the Merkel could be a pump. I LOVE pumps. There are so few made now. And would love to see more. PS. My favorite pump is a IMI Timberwolf in 357.

[@UnitedStatesOfGuns]

I missed that one! I tried to buy a Timberwolf at an auction - no success. How does it lock?

[@bobgarr6246]

I don't know if I'd say it was my favourite. I do love my Winchester M-62. And have an affinity for the Savage 170, Remington 760 and 7600, and the Colt Lightning. I was never crazy about the Browning BPR though. But that IMI Timberwolf .357 mag is as tough as nails , slick as snot and with that heavy barell is dead on accurate. With a little Aimpoint red dot on top it is super fast to handle and sight. The trigger and fire control group are 100% Remington 870, 760, 7600, 1100. Completely functional and proven. The adjustable butt stock is a great idea that works well. If I had to find a detractor I would most adamantly have to say it was the integral top rail. Of the Picitinny rail style but milled as part of the receiver it fails as having tolerances that fit Weaver style rings correctly.There is way to much slop between the milled cuts to properly accept rings with any precision. In every mounting instance and combination they have had to be shimmed. If the rifle was not so sought after, and holding such a premium I would mill off the rail and drill and tap for conventional rings and bases. And probably recess crown the muzzle. But I agree, it is a GREAT rifle !!!

[@bobgarr6246]

@@UnitedStatesOfGuns Hey Buddy, I just came across your post. If you don't already know, this is how the IMI Timberwolf locks up. If you are familiar with firearms of the Remington 870 family you will see that the entire fire control package is the same for the Timberwolf. As for lockup, the bolt has a milled cut up thru it's center for a freely moving up and down locking block, the bolt and block sit on the bolt carrier which is connected to action rails/arms that go to the forward pump/grip. When pumped, the bolt and bolt carrier move forward or rearward and slide across one another. A pad on the bolt carrier raises or lowers the bolts locking block as they slide across one another. This allows the locking block to engage the cut in the receiver roof for positive lock up or drop down to cycle the action. If you are at all familiar withe the Remington 870 family you will see that this is identical in design and function. Again, I appreciate and enjoy what you do. Bob

[@bobgarr6246]

Most long guns could be converted to pumps, and many have to avoid legal restrictions. There is an AR- 15 clone sold that is a pump. But semi autos are the easiest to adapt and convert to pumps. Bolt actions can readily be done, however overcoming the mechanical advantage the cramming surfaces the bolt handle has is an issue with a pump. John Browning converted a lever gun to semiautomatic, and Bill Ruger converted a Savage 99 to semiautomatic. So it can be done, but is easiest for semiautomatics to be made into pumps. I would have to say that trying to convert an O/U or S/S shotgun to a pump would be an exercise in futility and one he'll of an engineering challenge !!! But there is ALWAYS some gunsmith willing to try.... just not me !

[@CharlesinGA]

Mauser, in the late 1990's made a M96 which is a straight pull action with 16 locking lugs divided into two rows of 8 lugs, thus the head of the bolt need only rotate a small amount compared to most normal rotating bolts or straight pull rotating bolts such as the Steyr.

[@UnitedStatesOfGuns]

Hi CharlesinGA, I have been looking for one for a long time. The bolt handle is far forward - which is always interesting to me. Thanks for mentioning.

Hi, love your videos. The content and variety of rifles from around the world are incredible. I appreciate your sincerity and humbleness. Have you acquired the Browning Maral? If so how would you rate the Browning Maral in the straight-pull bolt action category? I would love to get my hands on a Maral mainly because I'm a big fan of John Moses Browning. When I graduated from college in the early 80s and could afford a good shotgun I bought a Citori Lighting and have been a loyal Browning customer since. I have seen a couple of Aceras in great condition and reasonably priced but I agree on the length or stretch to manipulate the bolt is too long.

The "petals" on the Blaser are what are known as collets in English-speaking machine terminology. In this specific instance, they are acting as an internal collet since they spread outward to grasp the interior of another part instead of clamping inward to grasp the exterior.

[@tomfuller4205]

Collets is actually a French word (actually collettes) transliterated as tabs so petals could be an actual translation. Similar to the French sabot meaning shoe.

Straight pulls are probably my favorite after slide or pump action rifles, but the straight pulls are probably more rugged and practical.

[@denisleblanc4506]

I don't see how some of them could have a strong primary extraction of stubborn cases using a simple straight pull action. I'd also be worried about durability if you rely on a couple or more ball bearings but then if HK can make semi-auto's with only 2 rollers to delay the opening, I suppose a few ball bearings could do it. I think my favorite would be the Helix. If they are willing to stand up to those huge boars with them they must be reliable.

Please Answer me , the matching locking recesses in the Heym SR30 are six individual spheric holes or a single ring machined in the receiver? Thanks from Brazil

[@ragnar338]

What is missing about the Blaser Radialbungverschluss: real 360 degreee locking and not in a collar but directly in the barrel so maximum possible accuracy also retaining point of impact when shot hot (this might be something worth paying for - it sure cost more to manufacture). The R93is said had issues with magnum cardridges overpressure so they redesigned the locking collar. The Trigger under the magazine is not only a safety measure but it is somehow overlooked it has a teleskoping bolt like a Mauser 66 since the trigger is under the magazine and the bolt has not to be guided by the system when behind the magazine the overall length of the rifle is reduced by the length of the magazine. The helix can lock up with dirt or bad rounds since the machanism increases the movement of the bolt but at the same ratio reduces the force applied heard from owners having problems with cheap practice ammo - a pump action is a great idea, no legal issues but German hunters are really stuck in their traditions.

[@UnitedStatesOfGuns]

Good comments Ragner! The R93 has a more sloped locking collar and the R8 has a larger and sharper shoulder. I think they wanted to be sure that the mechanism would open when the collar was allowed to collapse to its original size by moving the bolt handle backwards on the R93. So they made the locking edges more rounded. The R8 is more certainly locked and since it is a larger bolt overall - they can use a more severe lockiing ledge. I like the design of the Blasers - the lock is more or less a circle of flat springs - quite clever.

[@michailpanchev9952]

Actually, the term, that suits that kind of locking most is collet locking.

[@joepalouka1]

Can you take a Remington 742, 750, type, and alter it to be a straight pull bolt, by removing the springs, etc.

You talked about straight pulls and didn't mention the K 31?! 😱😱😃 The Browning is a really interesting idea that I'm surprised no one else has tried. Great solution to places that restrict semi autos. I don't know if it applies, but the Winchester sxp pump shotgun uses a rotary bolt, so that the pump travels much less to achieve the same effect. It's a shotgun, not a rifle, but it does what you were talking about. Thanks for the vid. A couple beauties there

[@UnitedStatesOfGuns]

Great point Jim - sorry. I also forgot the Ross and others. I guess I was thinking of commercial and sort of recent rifles.

[@jimf1964]

USOG Yes, I could see you were. No worries. I was just slightly surprise you did t throw one in, just for the heck of it, but you were obviously showing high end sporting guns.

[@DMX-PAT]

I was thinking how there's several different type of straight pulls, you've got the stationary straight pull such as the Merkel & Browning (where the bolt doesn't move) Then you've got the pivot or turn-pulls such as the Heym, Mauser 96, Blaser & Chapuis where the bolt as to perform a minor preliminary movement in order to unlock it...

It is a fascinating area - I'm still waiting for my Steel from Germany. So many developments and new rifles. Fantastic.

[@philippefrater2000]

The Swiss K31 is also a very Interresting straight pull riffle. I have to say the Browning "Marral"? with its automatic return locking system is calling me... 🖖🏻🇫🇷😎🇫🇷😇🇫🇷😎 (I'm a Browning owner)...

[@martinstiastny7679]

I'm not sure where the beginning is with straight pull rifles. Though I've only handled one ONCE, the 1895, 6mm Lee Navy was an interesting firearm.

Best rifle Lynx from Finland

[@UnitedStatesOfGuns]

Hi Kari - you may be right! I've been trying to buy one for years - no luck so far.

What does the suffix R mean at the end of a chambering such as 9.3 x 74R

[@CCV60202]

Re: the locking mechanism of the Blaser Bolt, I am familiar with electrical terms and those fingers are similar to what is mounted to the contact points of medium and high voltage circuit breakers. In that field they are referred to as rosettes the gripping area is aided by coil springs wrapping the neck of each contact point very similar to what you are displaying there. I was recently attracted to the Merkel . I currently am interested in the Kreighoff pump called the Semprio did you do a video on that model by any chance?

[@UnitedStatesOfGuns]

Hello - That's interesting about the circuit breakers! Yes - we had a Semprio - quite and amazing system. The video is somewhere on the channel. The Semprio is hard to find these days - I wonder how many they are building and selling. Cheers.

I own a small collection that is mostly out of production. I have an SHR 970, Sigg with two barrels currently wearing the 2506 and I have the 3006. I have a savage 99 and 308 with the brass internals it’s currently wearing your favorite iron sights not the original. It has the front site but the rear has been replaced with a red field micrometer Hunter peep intact very good condition. I had it reloaded and colored FN 300 supreme in 270 it shoots Walmart ammo touching holes at 100 yards I haven’t taken it to 200 yard range yet that is scoped. I have a savage 10 ML two muzzleloader, which was the one that was made to shoot smokeless powder it’s very accurate, I feel it shoots better with nose bullets than it does with plastic pointed bullets. And I have one rare pump the browning BP it’s not made anymore but it has a unique cantilevering pump action. Maybe if you have one of those you can do a video on that And I have a Remington 7600 which actually gave me a lot of problems when I first bought it but I since had them all resolved it’s currently wearing avoid stock that I bought from Cabela’s to replace the original synthetic stock. Of my disappointments in the 7600 model is, it is front they replace the center slide tube with two sliding rails but it’s still front heavy and I have a car with the 18 1/2 inch barrel. It is a love-hate relationship because I really would like to get rid of it however, it just keeps shooting straight, I can’t stand it! I am looking forward to getting one of those semipros. I also want one of those Helixes.

[@Kman31ca]

I still love my K31. lol But the day I can afford one of these, especially the Blaser, I will be a touch poorer.

[@UnitedStatesOfGuns]

Hello - your K31 is excellent - as you already know. If you do buy the Blaser - you won't be poorer - you'll have a Blaser worth more than the money you exchanged it for - which is paper at best and in and of itself, useless, and can't shoot. : )

[@noumanxd537]

All guns and rifles will be export quality.

[@eirik101]

Tried to look up a Brownin Maral for sale in US, could not find it, on Brownings EU site, it was all the rage. Any info on this.

[@moritzs.2895]

Please try some innogun rifles. They‘re amazing but get less attention than the other brands.

[@aaronbuckmaster7063]

A short throw pump action. 🤔 interesting. That could be done with a traditional internal operating rod replacing the bolt handle. What about the forearm. In my mind I see a forearm that moves within or maybe outside of itself. Being as short as 2.5 to 3 inches.....I’m thinking of how that could be configured in an elegant design. Having an independent forearm would be easy enough, but how to configure it to appear as a traditional one piece stock. This is interesting. You know, what about reversing the function to create a short throw push - pull action like the Krieghoff Semorio. That rifle has my interest in that you are pulling the rifle into a shooting position as you close the action. It’s much like a return to battery configuration. Imagine how fast that rifle would be with a three inch throw. Oh I like that. How does that sound.
