Battle Arms Development Lightweight 16" 9mm AR Barrel – 1:10 Twist, AR-15 Pattern

The Battle Arms Development Lightweight 16" barrel converts AR-15 pattern rifles to 9mm Luger operation, offering reduced weight without sacrificing accuracy for pistol-caliber carbine builds. Engineered for blowback 9mm uppers, this barrel delivers consistent performance for competition shooters and home defense applications where maneuverability and reduced recoil matter.

Manufactured from 4150 chrome moly steel with a black nitride finish for corrosion resistance and barrel life. The 1:10 twist rate stabilizes common 115gr to 147gr 9mm projectiles. Requires a dedicated 9mm bolt carrier group and magazine block or lower receiver. Standard carbine-length gas system placement allows flexibility in handguard selection.
