This AR-Stoner M4-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 light to medium weight projectiles of up to about 69 grains. The barrel’s M4 Contour sheds excess weight and bulk. This barrel is an excellent choice for a low budget, general purpose AR rifle build that’s perfectly suited for use at the range. Barrel extension and locator pin are both included and factory installed.
