i kind of forgot about this thread, started tinkering with my blowback ak now that 7.62x25 is again on the market. i think mine is going to feed fine with the 43 mags though my mags are as far forward as possible with a factory feed ramp in my front trunnion, i also pressed the barrel back a touch so the bullets have a shorter distance to the chamber. i just need to finish modding the pps-43 bolt and weld it into an akm carrier, rivet the trunnions into my receiver then lots of function testing
