YHM 20° 1:7 Fluted Target Crown Melonite QPQ AR-15 Barrel

This Yankee Hill YHM barrel features a 5.56x45mm NATO chamber for full compatibility with surplus mil-spec ammunition or commercial 223 Remington ammunition. Constructed of 4140 chrome moly steel, 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 especially in states that do not allow a threaded barrel. It is perfectly suited for use at the range, in a 3-Gun match, or in the field pursuing game.
