I just picked up the $799, folding stock, Vepr 12. I have a few untouched Saiga 12, AGP Gen 3, rock-and-lock 10 rounders, so I decided to convert them to work in the Vepr 12 instead.
I wanted to show you guy what I had to do to make them work in case anyone wants to attempt the same. The picture will be referring to the text above it.
The front lip/lug needs to be removed, obviously. I took it to just a hair or two past flush with the magazine.
The two ribs on the back of the magazine needs to be removed to be flush with the back of the mag.
This is where the LRBHO lever hangs. I took it about 90 degrees instead of the slope on the left side. (Mine isn't perfect in the picture)
Regarding the next two pictures. The rear wall of my magazine, right behind the real lip/lug, is a lot thicker than the factory 5 round vepr magazine that came with the gun and the LRBHO lever does not go past it. I had to remove some material so that the lever could sit in an unengaged position. Be cause of this thicker wall my LRBHO will not engage on the follower.
Lastly, this is what kept my magazine such a snug fit. The material for the screw housing needs to be removed a couple hairs until the mag will smoothly go into the mag well.
The magazine fits very snug, but like I said, mine will not engage the LRBHO.
The mag also does not currently eject itself from the magwell when the mag release is pressed. However, Mullet Man suggests splitting the magazine and opening up/raising the follower channels, and this will fix that. I have yet to try it, but it appears legit.
I haven't had time to shoot the magazine, but I see no reason why it shouldn't work.
Feel free to throw up any questions or comments. Hope this helps anyone that wants to attempt this!
