I picked in trade this 300 Blackout upper that I remove the Krylon camo paint from and had it Cerakoted Graphite black. I don't know the round count but the rifling looks clean and crisp. 1x8 twist, no bcg or charging handle. YHM quad rail forearm. For a local sale I'll include 40 rounds of ammo I picked up for this but never shot. 1 box of 220 grn and 1 box of 120 grn Hornady. $250 local, I would ship it minus the ammo for my cost FedEx ground.
