5.56 and .223 AR-15 Barrels
5.56 AR-15 barrels from Ballistic Advantage, Faxon, Rosco, and many more to fit your build no matter your budget. Most barrels you’ll see are Black Nitride finished, which is a corrosion-resistant treatment that preserves the accuracy of the rifling. Stainless steel barrels tend to be more accurate, made of milder steel that’s easier to cut precisely. Chrome lined barrels also offer excellent corrosion resistance, and are typically used in military barrels for toughness in harsh conditions and high volumes of fire.
