i have an AR with a surplus arms & ammo upper and lower receiver duracoated a FDE, m4 collapsable stock. complete -charging handle. upper has a 14.5" barrel (says BCM) with muzzle break that has vise grip marks on it (no not from me) i took the barrel in on trade and was gonna switch out the brake and have a new one pinned and never got to it. so the upper and lower will be separate so there wont be any trouble. easy fix thats why the price. all parts are new unfired except the barrel. $550
