Availability: In Stock
The Faxon Firearms Muzzlok .450/.458 Caliber 3-Port Muzzle Brake is engineered for shooters running large-bore AR builds who want serious recoil management without the field-swap hassle. Built in steel with a durable salt bath nitride finish, this brake threads directly onto 11/16"-24 barrels and uses Faxon's proprietary Muzzlok system—a timing adjustment feature that eliminates the need for crush washers or shims entirely. Whether you're running .450 Socom, .458 SOCOM, or smaller cartridges through a short or mid-length barrel, the three-port design captures and redirects propellant gases to the sides, meaningfully reducing felt recoil and improving control for faster follow-up shots and better target acquisition.
What sets this brake apart is the Muzzlok nut itself: rotate it to dial in your muzzle device's timing without fighting a crush washer, then torque to spec (20–25 ft-lb). That simplicity matters when you're running drills at the range or out in the field. And because there's no crush washer binding the device, you can remove and reinstall it on the same barrel as needed—no permanent installation, no accessories left behind. At just 3.2 ounces with the Muzzlok nut, it won't add unnecessary weight to your muzzle.
Faxon built this brake for the shooter who values reliability and practical engineering over marketing fluff. It's the kind of accessory that works the same way on the first shot and the thousandth, with no fuss and no surprises.
