Yes sir, that's why we have them :Dd piece of american weapon freedom in the middle of the Europe, that is CZ.

Any gun manufacturer with faith in their product should be more than happy to have people shoot their products. If they work flawlessly, then that's great marketing. If issues occur: ample opportunity for ironing out kinks to further perfect the product.

At least attempted!

@@sevenproxies4255 true. This is a 40 year old prototype that never made it to production, so critique away. But there is a lot of cool design to learn from off that little thing.

@@CrashRacknShoot I like a lot of design elements of it. And as far as the full-auto problems Ian had on the range, like you said, it's a prototype. And in my expience, misfeeds and trigger reset failures usually bottles down to the piece just needing some more machining. Some material needs to be added or taken off. But that's part and parcel of gunsmithing after all. This gun clearly doesn't need that much work to function flawlessly.

Mag should be in the grip tho

@@j.yossarian6852 not if it affects the design and functionality but an extra mag holder in the grip could be nice tho

@@j.yossarian6852 Exactly my thought. With that, a longer barrel would be possible. But the upper reciver must be extended to make room for the bolt but if you extend the upper the lengh of pull could also be improved. But the gun would not be as compact as befor.

Really reminds me of the pp-91, minus the lever delayed action, it’s remarkably similar

ΧD kekw ~~~ so true....

Also the Hungarian Kiraly 39M/ 43M submachineguns

@@jakubdolezal665 oh yeah, almost forgot about that one

Your user picture brings me back. Thumbs up.

The AA-52 is the French GPMG since 1952.

@@garthenar nice to find a fellow fan of the show on here

It is, isn't it? I was thinking the same thing

I was just thinking looking at the thumbnail, there seems (at least to me) to be a running theme of "cool looking" firearms becoming failures for one reason or another. Its shame, because these firearms are cool obviously 😅

Agreed, it's a simple design perfected and made elegant as an result.

Looks like russian smg PP-91 KEDR

It looks like a M3 Grease Gun that got caught in a vice.

That is very high quality for a one of its kind prototype! I'm impressed!

I'm no gunsmith, far from it, but I could see a couple of improvements that would have helped the ejection - like filling in that big empty space above the chamber a loose shell can fit into and a deflector to make sure the casing has only one place to go during ejection. Also, I wish Ian had worked the selector switch back and forth with some "emphasis" to make sure it was fully seated in the auto position.

I suspect that CZ did not pursue this design because they figured it won't be possible to make this thing out of stampings.

The problem isn't the magazine, I think, because Ian wasn't having trouble with an empty chamber.

Maybe it’s because he’s holding the magazine too tightly

Yesss, the skorpion stock looks right at home here.

It also looks like there's not enough kinetic energy in the cycle to do everything it's trying to do. Might be cause the main spring is too cold, not quite as responsive as it should be.

@@jono3952 I was thinking that maybe the chamber isn't fluted, that could rob the action of necessary momentum, the H&K delayed blowback guns all have fluted chambers to stop the case from sticking in the chamber...

I believe extraction is fine, because it works in semiauto. Ian also attempts "to recock the hammer without losing the round." So I believe he's ejecting unfired cartridges, rather than empty fired cases that failed to extract. The hammer possibly follows the bolt down too gently/early, not striking the primer hard enough to fire. So now you have a chambered round and uncocked gun. In semiauto, the disconnector prevents the hammer from "following" and it works fine.

Agreed. It looks like it has the possibility of being a handy pdw type of gun.

Maybe it is the ammo. Sadly Ian didn't mention what he used and if he tried different types or if this is the rated ammo.

@@wurstelei1356 Czech republic produces ammo, so it is unlikely to have variations in quality due to change of supplier. I mean, they run gun testing in the factory, not a shooting range for tourists.

@@Pyrochemik007 yup.. Sellier & Bellot being one of the oldest and well established ammo manufacturers in the world is located in Czech

Its Findorak work as well, same like CZ 805 and others rifles

If I am not mistaken this is also L. Findorak's work based partially on Baryshev's design.

@@CzechoslovakGunStories Yes it is

@@CzechoslovakGunStories Do you know of any videos or other media about it? I'm really interested in it, yet the only thing I managed to find is a low quality test fire video.

@@adh615 I will see what I can do :)

Yeah, the only one I knew of before googling it was the FAMAS, and there aren't very many at all. I remember reading that H&K tried making a lever-delayed SMG (an early MP5 or UMP prototype, or maybe the MP7?), but gave up. It seems to have some inherent problems that just make it hard to get right.

@Peter smith The ammo is the easiest thing to rule out. No repairs, no modifications, just different ammo. I'm not sure if hotter or lighter would be better, but I am somewhat disappointed that it wasn't investigated here. My gut says hotter, but who knows?

I agree, because I used to have the same issue with an older Century C308 that I had. I went too long without cleaning it once, and it had trouble with hammer follow and I'd get random 2 or 3 round bursts out of a semi auto rifle. And then after that 2nd or 3rd round I'd have to charge it again and reset the hammer because it was following the bolt. Needless to say I cleaned it every time I shot it after that happened.

I guess it's because it is a prototype rather than a production model that's had all the bugs worked out.

From what I can see in the footage, it appears that the trigger axis pin was too short and walked to the left little bit, which would cause an alignment issue with the trigger. It would still be able to effectively fire, but resetting would be problematic and prone to errors in that case (same with an AR15, or any other gun that has a very "neat" trigger group without a lot of horizontal space to shift aroudn in).

Maybe the magazine springs were weak? I was thinking the magazine wasn't able to keep up with the bolt.

A little more R&D and they may have something. The delayed action is a good idea in a small SMG. What’s old could be new.

The Skorpion is already that gun, albeit in a small caliber.

Me too. Did the lever delay system ever fit into a 9mm pistol? When I'm bored I try to imagine a delay system that would only minimally add to the complexity of a straight blowback design, i.e. keep cost and parts count and manufacturing time to a minimum.

@@donjones4719 I’m not sure, I think I heard about one on forgotten weapons before but maybe I’m just imagining things hahah, if there were I’d assume it was Czech or maybe Chinese before communism

Yeah, you are right. That is why Ian corrected himself that it is a delayed, not a locked system. I guess it is formulated in this (a little) incorrect way to make the explanation a bit simpler and shorter - the bolt movement prior to the lever retracting is small enough to support the case enough to prevent detonation and thus not as important to the overall picture. On the other hand, I can see that in this case, it may confuse someone, for instance, if they are well familiar with levers and not so much with the chamber - case - bolt - not-blowing-up setup. I wonder if there are more people benefiting from the amplification or if more people would rather have the full picture... I think Ian has some short videos explaining basic operating principles.

That's exactly what it is

a lot like a kedr

It would also allow you to have a longer folding stock with a locking tab at the front rather than the wonky push down to fold out action. It would still retain its small folded frame and probably be a very nice little SMG.

That would have increased the weight by quite a lot.

@@alltat Nah, don't think it would've been a problem.

I heard every Swiss has an assault rifle locked at home, in case of war. How about voting to allow soldiers to pick any Nato standard rifles? Then you can have Bren 2.
