The upper assembly comes equipped with a chrome lined, diamond fluted 4140 chrome moly steel barrel, 1 in 7" twist rifling and M4 feed ramps. This unique barrel profile is complemented by YHM's lightweight, free floating rifle length Diamond handguard. At 12.58" in length, the Diamond forearm bridges the gap between the barrel nut and the upper receiver's flat top rail for a clean, monolithic look, and also accommodates any number of tactical accessories via its 4 full length Picatinny rails at 12-, 3-, 6-, and 9-o'clock. Additional features include an effective Phantom 5C2 flash hider, a set of flip up iron sights, a low profile gas block at the carbine gas position, a commercial bolt carrier group, charging handle, forward assist, brass deflector and ejection port door. Made in the USA.
