The Ballistic Advantage Modern Series 12.5-inch .308 Win AR-10 Barrel (Ballistic Advantage part no. BABL308008M) is a short, carbine-length barrel for DPMS-style .308 builds. It uses the Tactical Government profile and is machined from chrome moly vanadium steel with a QPQ corrosion-resistant finish. A 1:10 twist and a 5/8×24 threaded muzzle make it ready for a flash hider or suppressor mount. For a compact 308 pistol or short rifle build, it keeps the package light and handy.
