1. BCM M4 Upper receiver / Douglas 5.56 NATO 1:7 twist SPR Profile barrel 1/2-28 threaded muzzle - chambered by Compass Lake Engineering - 1,500 - 2,000 rounds of 77 grain down the pipe, slow to moderate precision firing schedule. Will accept Allen Engineering Brake/collar for AEM5/OCM5 suppressors. Shoots nice tight 3/4" MOA groups with 77gr factory match ammo. Slightly better with reloads. Upper receiver face was lapped prior to barrel install; barrel extension bedded with Loctite 620 for a very tight and uniform mating surface. You're not separating the barrel from the upper without getting it extremely hot...therefore I'm selling this as a pair ------------------$300
