AR-STONER Barrel AR-15 Pistol 223 Wylde Government Contour 1 in 7" Twist 7.5" Chrome Moly Phosphate

This AR-STONER™ AR-15 Pistol Barrel is fully chambered and ready for installation onto a host upper receiver. The barrel uses the popular and versatile 223 Wylde chamber, which has a longer throat than the SAAMI spec for 223 Remington to allow for the safe usage of 5.56x45mm NATO ammunition and enhanced reliability. However, accuracy potential is also greater than a 5.56 NATO chamber due to slightly tighter tolerances, making the 223 Wylde an ideal compromise that retains the benefits of both of the other two chamber options.  The 1 in 7" Twist Rifling is capable of stabilizing light to medium weight projectiles of up to about 69 grains. This is the perfect barrel for a value 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 defensive carbines and/or PDW's. Barrel extension and locator pin are both included and factory installed.
Please Note: An "AR-15 Pistol" barrel is less than 16" in length. Pistol barrels are only for use on AR-15 pistol lowers and legal Short-Barreled Rifles. Other configurations may violate Federal law.
