mark9mmpThis is a mashup, Adams arms piston with KAK 762x39 bolt and billet upper meant for AK mags but will run with 762 AR mags as well. Midwest industries rail. A nice way to run 762 with ak mags in an AR. The piston makes it run way better suppressed too. The upper and handguard are cerakoted. Could be converted to 556 with new bolt and barrel Will trade/partial trade for 5.56 ammo.
