but why would you wanna aow if its presently OTC?  i emailed K-usa and they said their receiver is the "gun"  i think the s-12 is the front trunnion, what about the vepr? 

It can be made a lot shorter and lighter by doing a 6.5" or 8" AOW with the gas system relocated. It will also run much better on a wide range of loads. It is indeed cool, but some people want more than what it offers as-is in the envelope of 'other'.

 

Wherever the serial number is the 'gun' is. Vepr-12 serial number is on the trunnion.

interesting...  the aow route never aligned with my state/localities masters so i never pursued it...

 

i asked the question over in the sbs section, but couldnt a longer carrier piston be used, bore a hole through the puck, and let the carrier piston extend through the front of the gas block, like an AA-12?  wouldnt need to weld the tab on.  and maybe could reuse your pistons etc, instead of fabbing a new one?  seem like it would be a bit more work, but i dont weld...(barrel hood, for when carrier comes out of gas tube/guide

My 6.5" carrier comes well out of the gas tube. I'm sure you've seen it run by now. I have a means of addressing it.

 

Where is this tab you are talking about?

so whats keeping it aligned?  ive seen it run, but havent seen your fix...

 

watched a buncha your vids but didnt see detail

The tab is typically welded to the front underside of the dust cover.  The carrier bounces up as the rod stub leaves the tube.  The tab reduces the amount of pry and resistance the bounce can cause against the rails and also keeps the stub down low enough that it doesn’t crash into the the upper edge of the tube on it’s return.  

Ill have to get me one of those Spetz and check out what they are doing.

Oh yeah, that tab. I don't do it so quick and dirty. Mine isn't that simple or a welded shim and takes a lot longer to do, but works extremely well.

There is a cause to everything. From here, it looks like the pin was drilled at an angle instead of horizontally. Where this pin is visible on the outside of the gas block does it look like the hole is much higher on the left side of the gun than the right side. If it is in there at an angle and the cause of the thread issues a tap should cut threads in the pin just fine, but if the pin is ever removed it is going to have to go back in exactly like it came out or you will need to run a tap through it again.

I have a pretty busy day today, but if I can remember I'll check a Saiga-12 gas regulator and see what the threading is.

It looks like it is at an angle. Kind of a redneck test but putting in the plug a couple a couple times when clean it looks like the lead thread on the gas plug gets folded over a tiny bit so I'm guessing its hitting the pin as it goes all the way in. New gas plug and a bit of thread chasing should fix it.   

   After 300 slugs on position 1 (150 each range visit) gun is running ok but won't feed more then 5 rounds out of a magazine and dosent like the drums at all. Position 2 felt over gassed with same slugs. Guessing to much drag with mag tension. Dont want to smooth anything out till I figure out the muzzle threads since AWS is very clear that warranty is void if you do just about anything to it.

The number 2 setting is way too much gas for some high brass rounds.  The number 1 setting is not enough for most.  It is a poorly thought out gas plug.  Better than the original Saiga-12 gas plug though.

I have a dph plug in it right now, ran 100 rounds though it today and I could get it out, the knurling on the dph is almost 3 times as high as the I'm guessing lynx plug.  It's the pin not straight in the gas block that hangs it up. During my full teardown today I also noticed my gas block is off of a different gun. Evey other part is stamped 935 then the gas block is stamped 944
