Well, this has been a little project that I have been working on for a little while. I got a "ak parts kit" for Christmas. The kit is basically an ak-47 with the receiver torch cut so that it can be legally imported into the US. You can buy 100% complete us legal semi auto receivers and re-assemble it into a functioning gun, as long as there are no more than 10 imported parts. On an AK-47, there are 16 total counted parts, so I replaced the pistol grip, the fire control group(hammer, trigger, and sear count as 3 parts), the muzzle brake, and of course the new receiver.
Instead of buying a complete receiver and having it transferred through an FFL, I decided to try to bend one from a "flat". A flat is considered an 80% complete receiver by the ATF, therefore doesn't have to be transferred by an dealer.
The process is fairly simple and I think the pictures will show it pretty well. You can buy bending jigs to use on a press, but I came up with something a little different using stuff out of the scrap pile and something that doesn't require a press since I don't have one.
On to the pictures...
the flat as it comes, cost is about $13:
My home brew jig:
How it works:
The bent receiver:
Test fitting before bending the top rails:
Assembled and test fired:
I still have to refinish the stock, but otherwise it is complete.
*Not shown is welding or screwing the receiver to the front and rear trunnions and welding in the lower rails for the bolt carrier to ride on.
;D
