The Ballistic Advantage Classic Series 5.56 NATO 16-inch Heavy Barrel (HBAR) is a precision-machined rifle barrel built for the AR-15 platform. Constructed from durable Chrome Moly Vanadium (CrMoV) steel, this barrel features a chrome-lined bore and chamber for enhanced corrosion resistance and extended service life. The manganese phosphate exterior finish provides an additional layer of protection, while the phosphate-coated M4 feed ramp extension ensures smooth and reliable feeding. With a 1:7 twist rate and mid-length gas system, this barrel delivers excellent accuracy and reduced felt recoil across a wide range of 5.56 NATO ammunition types. The 1/2x28 threaded muzzle allows easy attachment of muzzle devices, and the heavy HBAR profile is prominently engraved for quick identification. The .750-inch gas block journal accommodates the most widely available AR-15 gas blocks, making this barrel a versatile and dependable upgrade for any build.
