Weighing in at 4.8 oz. and measuring 3" in length, the black nitride coated steel Big Timber Brake was designed to not only be an outstanding muzzle control device but also to eliminate the gap between 15" handguards and 16" barrels. The BTB is counterbored .75" allowing the brake to slide over lightweight and HBAR sized barrels, giving the shooter's rifle a smooth, clean appearance while virtually eliminating muzzle rise. The BTB is available in ½ x 28 tpi and 5/8 x 24 tpi allowing it to fit on most AR platform barrels. MSRP $99.99.
