Barrel Length:

Updated design for 2018.
This barrel no longer requires the use of a two piece gas block, the low profile muzzle device allows the use of any gas block with a .750" inside diameter.
This 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 features a permanently attached Low Profile Flash Hider (YHM-24-A) that brings the overall length of the barrel to a legal 16".

    As the title suggests this barrel is all about quality. The barrel itself with its fluting is a work of art. It’s light And it’s seamlessly married to the muzzle. I’m looking now to add a YHM barrel in a different caliber.
