Sleek and Lightweight 11.3 AR-15 Pistol Barrel

With only a .625″ gas block journal and the balanced Hanson profile, this barrel from Ballistic Advantage takes weapon handling to the next level.  This barrel makes your AR incredibly easy to handle, while preserving reliability with adequate dwell time and top-notch machining.  The barrel’s nitride finish also preserves the bore, which has a 1:7 twist for stabilizing heavier, match-grade ammunition.

If you’re planning to run a suppressor on your build, consider what muzzle device is best-suited if you want quick detachment.  The Gemtech Quickmount Flash Hider, or the Dead Air Keymount Muzzle Brake are both solid candidates.  Be sure to check out our full selection of muzzle devices for one to suit your build.

All Performance Series Barrels feature a Nickel Boron Coated Extended M4 Feed Ramp Extension.  Hanson Series Barrels also include a lo-pro gas block and coil pin, ready for permanent and secure attachment. These barrels are not designed to work with aftermarket piston kits.
