Match grade 16inch chrome moly fluted 1/8 Wilson barrel. A2 bird cage flash hider. YHM lightweight FF handguards. YHM gas block front flip sight. A3 flat top T marked upper receiver. Bolt and charging handle included. The charging handle also has an Ameetec tac latch. Approx 100 rounds fired. I'm just tired of having to buy match grade bullets for this since I will probly never shoot in a match. Asking $550 shipped. Or will trade for a 14.5 m4 profile flat top upper with rifle length free float handguards. I'm wanting the dissipator look.
