AR-Stoner Barrel AR-15 Pistol 5.56x45mm NATO Medium Contour 1 in 7" Twist 10.5" Chrome Moly Melonite Coated
The AR-Stoner pistol barrel features a 5.56x45mm NATO chamber for full compatibility with surplus mil-spec ammunition or commercial 223 Remington ammunition. Constructed of chrome moly steel with a threaded muzzle, the barrel is Melonited for ultimate surface protection. The melonite coating 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.
