The TacFire 10.5″ Unassembled 5.56 NATO Pistol Build Kit (brand part no. PK556-LPK-10) bundles every part needed to finish a 5.56 pistol build around a lower receiver you supply yourself. Made by TacFire, the kit includes a 10.5″ barrel, low-profile gas block, pistol-length gas tube, A2 flash hider, bolt carrier group, M-LOK handguard, upper and lower parts kits, pistol buffer tube, and buffer and spring, all finished in black anodize.
