Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

A1 & HBAR Factory Contours; Two Lengths To Choose From

Ready-to-install barrels let you customize your AR-15/M16/M4/CAR-15 or replace a “shot-out” factory barrel with one that preserves your gun’s original specs and appearance. Machined from 4140 steel, with a dark gray, military-type Parkerized finish. Button-cut, six groove rifling with 1:9 right-hand twist provides superb accuracy with most bullet weights. Barrel extension has M4-type feed ramps to help ensure smooth feeding and prevent jams. Barrel nut and handguard retainer cap included. Forged front sight housing has integral bayonet lug, and muzzle is threaded to accept the flash hider or compensator of your choice. Choose from Chrome Lined for maximum bore life or Standard (unlined) for an extra edge in accuracy. A1 has the correct dimensions and contours of the original M16A1 barrel in shorter, more compact 16" and 11½" lengths. Offers a substantial weight reduction (10½ oz. in 16" configuration) for carrying ease and faster deployment in combat, with accuracy equal to the heavier HBAR barrel out to 100 meters. Front sight housing is purpose-manufactured to fit the .625" forward barrel, not a modified .750" housing, to maintain correct appearance. All NFA rules apply to 11½" barrels.
