Unfired. KAC URX4 13 inch handguard, BA hanson 13.7 melonited barrel with pinned gas block, aero precision upper receiver, melonited gas tube. Perfect fit for snug suppressor mounting with minimal gap. Really really cool build. Upper was assembled using magpul bev block and everything is torqued to spec. Urx4 is timed perfectly. 650 shipped. Just need to raise funds for another project. no trades please. Gas block was pinned with zero modification to the handguard and both set screws are loctite as well. Thanks for looking. Urx4 is cerakote 50/50 mix coyote tan and burnt bronze
