This SOCOM Contour AR-15 Barrel is fully chambered and ready for installation onto a host upper receiver. The barrel features a 5.56x45mm NATO Chamber, while the 1 in 7″ Twist Rifling is capable of stabilizing virtually any 5.56 bullet. The barrel’s SOCOM Contour is similar to the standard M4 Contour, but eliminates the M203 cut, giving it a more streamlined appearance. This barrel is an excellent choice for any low budget AR project.

Chambered in 5.56 NATO for full compatibility with surplus MIL-SPEC ammunition or commercial .223 Remington. Constructed of 4140 chrome moly steel and finished in nitride for excellent surface protection. The 1:8 twist rate is great for stabilizing most bullet weights and the mid-length gas system is optimal for reliability and reduced recoil.
