7.62x39mm 1:9.45 twist
Machined in our shop from 4150 rifled blanks! These are stamped CHF 7.62 U.S.A. for 922r Compliance!.
These have the extractor cut, handguard retainer cut, and barrel threaded 14-1 LH. We do not drill the gas port since it is easy enough to do with a 45 degree gas block with a hand drill.
These will fit Romanian, Polish Underfolder, MAADI and other 1mm stamped receiver kits. The chamber end of the barrels measure .908" to .9085".
