  • Information
This AR-Stoner SOCOM Contour AR-15 Barrel is fully chambered and ready for installation onto a host upper receiver. The barrel features a true 5.56x45mm NATO Chamber for use with both commercial and military surplus ammunition, 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. Barrel extension and locator pin are both included and factory installed.
