i've been thinking about making some parts for a few projects myself and had a couple of questions for you guys. i was going to start with the rear tang, because it is fairly straight forward and not too critical of a part. my question is what would a good steel to use for it? i'm not sure how mild steel would hold up to constant battering of recoil, so i was thinking of 4140 pre-hardened. IIRC it has a rockwell of 30-35, but can still be machined fairly easily and i won't have to send it out to be hardened. thanks for any input you can give.

its not worth it
you can just buy 1 for 20 bucks and it wont count as a us part

if your looking for somethin to make make some hinge blocks for a krink
those are in vary high demand and would bring come good coin
they are also fairly simple and dont need to be hard :)

4140 would be an excellent material to use. It shouldn't need heat treating, as you mention. The RW is already good. I also agree with Candyman on sellability. Pistol trunions are pretty straight forward and there is a demand for them, too. Also, you may already know, but the rear tang is not on the 922R as a replacable part.

you guys can read my mind! Side folder krink/ ak100 rear trunions are part of my plan also. yeah i know they are not needed for 922r compliance, just have a need to tinker. down the road i would like to build a 100% U.S. made stamped AK(with most of the parts made by me). it'll probably end up costing around $10,000, but who cares. it's about the Ak and not the money, right?

The rear block is not a listed part anyway, it isn't a 'trunion'

Some people call it a rear trunion, some call it a stock tank and still others call it a rear block. Take your pick :grin:
