Product Information

This AR-Stoner AR-15 Pistol 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 9" Twist Rifling is capable of stabilizing light to medium weight projectiles of up to about 69 grains. This is the perfect barrel for a budget AR Pistol build, keeping length and weight to an absolute minimum while still offering a significant ballistic advantage over any of the traditional pistol chamberings found in common use in defensive carbines and/or PDW's. Barrel extension and locator pin are both included and factory installed.
