AR15 BARREL 556 16IN STRAIGHT FLUTED 1/8

Chambered in 5.56 NATO for full compatibility with surplus MIL-SPEC ammunition, this straight flute barrel is constructed of 4150 chrome moly steel and finished in nitride for excellent surface protection. The 1:8 twist rate is great for stabilizing most bullet weights from 55 grains up to 77 grains and the carbine-length gas system is optimal for reliability and reduced recoil.
