BCM upper with a 14.5” carbine gas socom profile barrel. These are highly regarded as exceptionally accurate barrels. Has a Knights Armament MRE (Modular Rail Extension) handguard that is very rare and can be $500-600 by itself. The 3 knights rail covers, stubby tangodown QD grip, forward controls keymo compatible muzzle device, radian raptor CH, and bcg are all included with the upper. Does not include a rear sight. The handguard does have some wear marks and is missing one screw on the left hand side of the rail extension so I am only looking for $800 cash, no trades. Text 21095468twotwo if interested.
