I just said “WOW!” a few times while watching this:
Like Hickok says you shouldn’t be afraid to take guns apart. I’m kinda odd as I like to field strip guns, but I get mighty timid as soon as it comes time to drive out roll pins and get down to the small parts. (I’ll have you know I’ve never had a really bad experience tearing down a gun in detail I just don’t like it)
Still I’ve taken a bunch of guns apart, and I’m at a point where it takes something odd for me to see something truly new.
Now I knew that the Vz-58 locks up via a tilting bolt face like an SKS or an FAL. So after reading that and looking at the gun’s bolt carrier from the outside, and knowing its Eastern European lineage I suspected they might look a little bit similar.
I wish he’d taken the bolt off the carrier now!
Didn’t really see the striker, I half expected it to look like the assembly on a bolt-action. Certainly the trigger bar looks the part.
Also did you notice the piston tube is open on the bottom? I think that means as soon as the piston kicks the bolt carrier out of battery most the piston assembly opens up to the big wide world and dumps all the excess pressure.
Just super cool to see something new out there.
Great video!
It’s not a tilting bolt but a tilting locking piece that’s separate from the bolt.
I keep seeing the “striker” referred to as a linear hammer for this gun, it hits the firing pin that’s captive in the bolt.
I’d rate the gas cylinder as being very short and open at the top too, just covered by the handguard. He’s right about several piston AR’s using the same idea.

OK It appears that many of the technical pages I read about this gun were wrong, and now that helps me understand what that extra widget I saw hanging off the bolt when he tore down the carrier.
You have any similar pictures of Piston ARs that roll like that tore down?
No pictures, but I’ve seen several. Osprey, for one, operates this way. I can’t recall the name off the method top of my head, but that’s a very common form of running a gas system.
A very short expansion chamber to get the piston going and then it’s all inertia from there.
I’m not a fan of piston conversions, it’s fixing a problem that doesn’t exist and creating its own. If you feel the urge to have a different gas system you should select a different gun altogether.
Cool thanks for the info.
Yeah I’m also with you. If you don’t like the Stoner Gas System, then you really don’t like the AR/M16 platform.
That’s fine, there are other guns that do similar things that were designed around a short-stroke gas piston system. You should look at those.
That being said I’m totally thinking your argument for FNH to bring back the FNC rifle…especially given what a worthless turd the SIG 556 is turning out to be.
the FNC easily would be the 556 without the suck.
Plus every time I watch Heat, I WANT one.
Thanks for this, I’ve always wondered about the differences between these two guns.
Huge, isn’t it?
Coincidentally I was just watching a video on how to detail strip my Glock, but I’m with you Weerd. I won’t go farther than a field strip unless I’m pretty sure I know what I’m doing lol. I’m mainly concerned about knowing when I’m about to send any tiny pins or springs flying so that I’m not missing parts later on.
I think disassembling pistols is more intimidating personally, since the parts are generally smaller and jammed into a tighter space. Worst problem I’ve had was with my XD, where I got the barrel jammed somehow during removal, wasn’t too hard to fix though.
Glocks are pretty simple inside from what I’ve seen.
Still why bother if everything is clean and working?
“Still why bother if everything is clean and working?”
I’ve learned that the hard way before with other things *cough*mycomputer*cough*. If it ain’t broke don’t fix it. Still, curiosity is great, just make sure you know what you’re doing or have a backup plan if you screw up lol. I’m not too prideful to ask for help if I make a mistake.
LOL the Optical drive on my old computer NEVER worked right. But I never needed it enough to bother to pop the case and possibly open a can of worms.
To be fair however, by making mistakes I’ve learned what I can and cannot do. I’m much better at diagnosing problems now and can usually tell if it’s software vs hardware, and if it’s even fixable.
I don’t like flying blind, but I’ve learned that you have take risks sometimes and make that leap to get ahead.
First thing I do after buying a new gun is take it apart. Especially if I’m unfamiliar with the make or model.
I do this 1 for my own educational reasons, 2I want to clear off any cosmiline from storage and lube it for operation. An ounce of prevention is worth a pound of cure in the maintenance department.
Takes time, but if it’s your tool you should know how it works, operates, and how to clean it.
I remember taking my Garand completely apart. There are some assemblies that are a lot easier to get apart than back together if you don’t have the special tools. Like the extractor.
Whenever I get a chance to break down something just so it can be scrapped or more easily fit into a dumpster or a garbage truck I often use this maxim: “It’s fun taking stuff apart if you aren’t going to put back together.”
When I’m tearing something down I’m always looking for points where I may find a pitfall putting back together, and sometimes it does me no good, other times I miss all the original configuration (like pulling the trigger group out of a Mossberg, or driving out the pin that holds the sear and disconnector on a 1911…you’ll need a drawing because gravity is going to drop those innards on your bench).
BTW this also translates to surgery vs dissection. Dissection is all kinds of fun because I’m just taking apart, and the remains are getting junked when I’m done. SURGERY this little baster is going to have to bounce back from all of this. NO FUN!
