recoil reducer by luke, Verified Owner, September 5, 2024
I bought a Mossberg patriot 450 bushmaster before deer season of 2023. I let my dad use it to see if he wanted one. He said he loved the gun and the knock down power, but the recoil was just to much for him. I told him before he bought a smaller cali...

Product Info for Next Level Armament NLX-11 Muzzle Brake

Designed the NLX-11 to mitigate muzzle rise and recoil. The awesome stopping power of the .450 Bushmaster delivers heavy recoil in the AR15 platform. Tame the beast with the best brake available! We precision machine each NLX-11 450 Bushmaster Brake from 4140 stainless steel raw stock and Nitride finish for a durable, long lasting part. Specifically designed to reduce recoil and muzzle jump, the NLX-11 enables the operator to achieve greater accuracy and deliver better followup shots. Whether hunting hogs or hunting deer, your rifle needs the best brake in the industry. Your shoulder will thank you!image

Notes: Due to the large diameter of the 11/16 x 24 .450 Bushmaster barrel threads, the crush washer is relatively thin compared to traditional .308 and 5.56 crush washers. We recommend hand tighten, then index using no more than 1/3 turn. If you over-tighten past 1/3 turn, you may snap the crush washer. Due to different thread points between barrels, do not try to index simply by our logo. We designed our brake to have a solid ridge up with port holes at 11 and 1 o clock.
