Coming along well! I started from the back and I'm working forward. Don't ask.
I'm making this a bullpup, and I've modelled the buttstock after the OC-14 Groza (my favorite!) and I'm modelling the bullpup action after it as well:
I didn't get it in the pic, but I have a rear sight block partially converted for a pistol build I never completed. Well, a little modification and presto I have salvaged it for the "mounting block" that will support an AKSU-style hinged top cover. The cover was beat up some, and I had to peen and flex it back to some semblance of parallel sides.
As you can see, I'm nearly finished with the buttstock. The buttstock will have a rubber pad as soon as I find something suitable. Not sure where to get rubber that thick, and it is larger than all the rubber stock pads I have. The buttstock, when locked, keeps the top cover from coming loose in the back. Sling swivel is coming soon. The hinge didn't turn out exactly as I'd planned, but it works anyway so I'm not complaining... just looks a little odd!
YES - that is a home-built magazine well! It works! As you can see, I haven't wire brushed it or sanded it all nice and pretty yet. I haven't even pinned the latch retainer pin into place yet - kept it loose while I was fitting all the pieces in place!
It is flared to help magazine loading. It will need only a rear locking lug, the clearance is just enough so that I don't need anything on the front. The front spine of the well doubles to cover up the opening of the original magazine well... it was big enough that I didn't want it exposed.
That's a Saiga receiver cover plate, I just cut it down and riveted it in place to cover up the trigger opening.
I also spring loaded the firing pin:
I'm going to use the original Saiga sear and disconnector, and the bullpup will use an original trigger I had laying around. That puts the parts count up one more for me to 17 as I'm building it, but I'm covered any way you slice it with the buttstock, magazines, barrel, and muzzle brake. I think I have 9 US parts total.
Next on the list is chambering the barrel, adding the gas block, the bullpup assembly, and loading up some rounds
