AR-STONER Barrel AR-15 223 Remington (Wylde) Heavy Contour 1 in 8 Twist 20 Fluted Stainless Steel

The AR-STONER AR-15 .223 Remington (Wylde) Heavy Contour Barrel is perfect for use in competition where accuracy and reliable function are important factors. This barrel is chambered in the popular and versatile .223 Remington (Wylde) which has a longer throat than the SAAMI spec for .223 Remington allowing 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 Remington (Wylde) an ideal compromise that retains the benefits of both chamber options.
This heavy contour barrel is manufactured from 416R stainless steel and button rifled. It is fluted along its length for greater stiffness, faster cooling and reduced weight. Additional features include M4 feed ramps and 1/2″-28 threaded muzzle. Barrel extension and locator pin are both included and installed at the factory.

Features:

• Chambered in .223 Remington (Wylde)
