Whether you've got an AR-style pistol or a short-barreled rifle that needs a new barrel or a brand-new build that demands a high-quality barrel, Colt's M4CQB OEM barrel is available as a dedicated add-on or replacement component straight from the same line that produces barrels for Colt's factory guns. Each Colt AR-15 M4CQB Barrel features six-groove rifling with a 1:7-inch rate of twist. The barrels include M4-style feed ramps and have a chrome lining that prevents corrosion. Each barrel is set up for a carbine-length gas system and features 1/2"-28 TPI threading at the muzzle. Colt's M4CQB Barrels are available in 10.3-inch lengths and can be had as a stripped barrel, complete with barrel extension, or as an assembly that includes a barrel nut, front-sight tower and post.
