Ruger made waves with the introduction of its American Ranch Rifle in 450 Bushmaster, a big-bore caliber that's popular with hunters across the country. However, the recoil of this large, powerful round can make range time tiresome, and nobody wants a flinch that can throw that one shot that counts. To combat this, Next Level Armament developed its NLX-11 450 Bushmaster Brake specifically for the Ruger American Rifle. Each Next Level Armament NLX-11 Bushmaster Brake is precision-machined from 4140 stainless steel and features the 11/16-24 TPI thread pitch needed for the large barrel. Due to the large size of the Bushmaster barrel, Next Level Armament includes a crush washer that's pretty thin compared to other crush washers. To install, simply hand-tighten the brake and then index to no more than 1/3 of a turn. The Next Level Armament NLX-11 Bushmaster Brake measures 2.5 inches long, .88-inch in diameter and is purpose-built to keep your gun on-target and ready for a fast follow-up shot.
