Description
The Ballistic Advantage Modern Series is a 12.5-inch government-profile replacement barrel chambered in 5.56x45mm NATO for AR-15 platform rifles. It is intended for builders and owners who want a carbine-length barrel with a threaded muzzle and a QPQ-finished steel body.
The barrel is machined from 4150 chrome moly vanadium steel and finished in black QPQ for corrosion resistance. It uses a 1:7 twist rate, has a 1/2-28 tpi threaded muzzle, and weighs 22 oz (1.38 lbs). It is supplied without sights and includes a QPQ-coated M4 feed ramp extension. The barrel is designed for a carbine-length gas system and fits AR-15 receivers. Ownership rules for barrels used on short-barreled or machine gun lowers apply, so check federal regulations before installation.
