If you search "saiga adjustable gas plug" you will see CSS who sells an aftermarket one that is nice, and another company that sells an autoplug which doesn't need as much adjustment

Probably around $40

First texture it with a soldering iron to make it rough, and then add the epoxy. Go bigger than you need and grind it down for fit. It will work for filling space but it won't be reliable for structural strength

If the grip mounts to a picatinny rail, I would just mount a short section of rail under the handguard with recessed screws and nuts. If that is not possible, post a picture of the handguard and I can advise further

It depends on which version of S12, the earlier ones with the long barrel were full choke with no threads

It's around $1,200

If you do a search on here you can find most of that. Also, I think it will fire folded

Who is that?

Maybe around $650

The things that will be hard to find are already hard to find. Basically anything specific to S12 that can't be adapted from an AK rifle

It won't match up exactly with a rifle receiver, but with modifications it should be possible to build. I think a 1.5mm receiver would be a good starting point.

It is not unusual for mags to need fitting. You have to figure out where the interference is and file off a little bit. Just do a little bit at a time. When you get it to lock in place with some effort, stop there because it will loosen up over time and you don't want it to be too loose.

Yeah, I part of the mag release will be behind the sight lever lock, but it is the thin part so it should work

If your are saying that the mag inserts all the way and seats properly, you can stop. But more likely that you will have to continue hogging out until you match the interior boundaries of the magwell

You do have to hog it out to the full interior boundaries of the magwell. It is scary, but people have done it and it works If you look around on here, there are examples of people who have done it

You have to start with the retainers that you can buy for AK handguards and then severely modify them with dremmeling and cutting, fabricate mounting clips or tabs etc, then do TIG welding, detail grinding and finishing. If you look around on here, you find examples of guns that people have done. You could also contact a guy named Dinzag, he has manufactured some of the parts. At one time, he had a bolt-on kit. It's actually not hard, it is just a lot of detail work, like building a model airplane or something

Thanks bro. So TIG welding is strong enough in this application?

Somebody with this type of barrel hood, can you please measure this dimension?

I don't think the magwell will interfere with a folding stock. The SGM magwell will work better with some mags over others, you would have to search on here for what others have tried that worked. Most mags can be modified to work in the magwell. Also, the magwell mags like the VEPR12 will work, although anything you do will require some fitting

There is a gas puck in there, it is like an intermediate gas piston to cycle the bolt. A regular AK doesn't have that. So it could be that had been stuck before with dried grease and you just loosened it up. Why not just take off the gas plug and pull out the puck and see if that was it.

You will first grind off the rivets holding your old trunnion in, and if the new underfolder trunnion is designed to fit that gun, they should have holes lined up with your receiver holes. If they don't, you would drill new holes in your trunnion to line up with your receiver holes. Don't drill new holes in your receiver

These guns should always be restored to their original AK design. The "sporter" importation configuration is goofy and an embarrassment, and nobody wants that. It's also easy to do and parts are available, so there is nothing to stop you

The shroud is cosmetic, so maybe just forget it? Put a brake or flash hider on instead

It is amazing that those parts hold up but the geometry of that is different and the forces have more dampening. With the magazine, the geometry of it relative to the recoil and the shockwave having no dampening, it puts the material is at a big disadvantage

Not 12 gauge. Also, that mag broke after that video
