<div data-cycle-hash="bg16-arup-bcm" data-cycle-desc="BCM Uppers: All of the BCM flattop uppers feature laser-etched “T” marks to make consistent remounting of sights and accessories easier. Standard uppers match or exceed GI specs, with 1-in-7-inch twist, chrome-moly barrels with chromed bores and 5.56mm NATO chambers. The barrels are subjected to the M197 high-pressure test load, rated for 70,000 psi, and then undergo magnetic-particle inspection to detect any possible flaws in the barrel's surface.
