My first attempt at the AK pistol caliber conversion.
This one is 7.62 x 25, Using the old Bulgarian 50's surplus.
It does operate well. I do have the occassional hang-up.
But, overall, it shits-and-gets. This is blow-back operated.
I used a bunch of left over parts. Threw in an FAL FSB
The head of an AK gas piston serves as a charging handle.
The magwell and mag is a PPS-43.
