BCM factory built upper with all BCM parts (except muzzle device is a factory pinned/welded Surefire sfmb). Magpul MBUS Pro rear sight. BCM factory built lower. Trijicon TA31 RCO, red chevron and bcd hash-marks out to 600m. Will only separate if optic sells first. Optic is ballistically matched to m855 through a 14.5” barrel with 1:7 twist, which this upper is. All items are like new, only seen 50-100 rounds for zeroing and larping. Almost like the M4s issued in the Marine Corps, but parts are nicer, the barrel hasn’t seen 20,000 rounds, and it hasn’t been abused by 9 generations of LCpls. Looking at trades for FDE cqbl, ddc Geissele super precision 30mm scope mount, aimpoint t2 on black 1.93 mount, mpx-k. Prefer local buyer, but may ship depending on offer.
