these mags were partially mod by rpbusa and wasn't told for what gun, the mags had the front of the mag ground down ,so i put a weld to put it back into original configeration, with robinson followers, and a 922 compliant saiga
just mod a few bakealite mags .223 with a welded feed ramp just like the factory mags and not one jam or feeding promlems, just wear a welding helmet, f*ck I burned my eyes mith the mig.
i just finshed my convert, but was wondering other options for the aluminium binding post for a home hobby guy, they seem very soft and would like steel
spoke with someone at rpbusa today an they said that no longer carry the tapco saw249 pistol grip. he said that the grip has the trapdoor in it and that a short screw was required and that people had complained that the grip would move around on them. so i bought an ERGO grip with SURE GRIP from brownells. it cost a bit more but looks cooool.
