See shipping and payment tab. Description copied from midway: This AR-Stoner carbine barrel features a 5.56x45mm NATO chamber for full compatibility with surplus mil-spec ammunition or commercial 223 Remington ammunition. These barrels are constructed of 4150 chrome moly steel with a threaded muzzle and barrel extension which features M4 Feed Ramps. Additionally, these barrels feature a melonite coating which provides a thinner surface than chrome-lining, so bore friction is reduced for better accuracy. In addition, melonite is harder than chrome-lining providing a longer wear life.
