The bore and chamber are hard-chromed to resist corrosion, simplify cleaning and reduce long-term wear. Button rifled from 4150 chrome moly vanadium steel, these barrels are chambered in .223 Wylde, ensuring compatibility with both .223 Remington and 5.56x45mm ammo. With a 1:8 twist, they handle everything from 55gr FMJ to heavier 77 gr rounds.
