Winchester Guns 611108340 SX3 Rifled 12 Gauge 22 in 3 in Cantilever Scope Mount Blk TruGlo Fiber Optic Frnt

This YHM barrel features a 5.56x45mm NATO Chamber for full compatibility with surplus mil-spec ammunition or commercial 223 Remington ammunition. It is a 16" fluted barrel with 1:7" twist rate. Constructed of 4140 chrome moly steel with a threaded muzzle (1/2"-28), 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. This barrel is an excellent choice for a general purpose AR rifle build. It is perfectly suited for use at the range, in a 3-Gun match, or in the field pursuing game.
