Hey guys so i just converted another Saiga 7.62x39 and it turned out beautifuly. What i was wondering is does the thing need to be broken in and the reason i ask is because as the piston makes it way into the gas block it kinda stiffens up. I think its because the piston is still stiff and hasnt loosened up yet as they do after about 500 rounds or so. I hope I explained this good enough for some good input. Thanks.
