Machined in our shop from 4140 rifled blanks!  These are stamped 7.62 U.S.A. for 922r Compliance!  No other US made barrel has any markings.

Non Chrome Lined.

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.
