Description

The Proof Research 16” .223 Wylde Carbon Fiber AR-15 Barrel (143254) combines the versatility of the .223 Wylde chamber — which accepts both .223 Remington and 5.56 NATO ammunition — with Proof Research’s world-class carbon fiber barrel construction. The 1:8 twist rate stabilizes a wide range of projectile weights from 55 to 80 grains for outstanding versatility in competition, hunting, and tactical use. At up to 64% lighter than traditional steel barrels of similar contour, this carbon fiber barrel dramatically reduces rifle weight while delivering match-grade accuracy and improved thermal performance for sustained fire. Made in the USA by Proof Research in Kalispell, Montana.

Proof Research’s carbon fiber barrels move heat very effectively through the barrel wall — resulting in barrels that cool faster, maintain accuracy over longer sessions of fire, and exhibit no point-of-impact shift during high-volume fire. Reduced harmonic barrel vibration further enhances shot-to-shot consistency. The 5/8”-24 muzzle threads make this barrel suppressor-ready, and the mid-length gas system provides smooth cycling with a wide variety of ammunition. Features M4 feed ramps and a 0.75” gas block diameter for standard low-profile gas block compatibility. This barrel fits standard AR-15 platform rifles.
