Posted 15 Sep 2017 (edited) From what I can discern, this is a .40 cal barrel (threaded) with matching mag. Barrel is stamped "40" and that's a .40 round in the muzzle. Mag locks up in a standard AR-15 lower so I assume it goes with it. Im glad to provide specific pictures to interested parties. No sales where prohibited.
