The Rex Silentium AR-15 Muzzle Lock Nut is a quality lock nut for the application of muzzle devices for the AR-15 platform. Using a lock nut makes timing and installing a muzzle brake much easier than it might be if you had to guess where to put a cone washer. Unlike crush and peel washers Rex Silentium's rifle Muzzle Lock Nuts are reusable and infinitely repositionable. The design of these nuts is such that they protect the threaded barrel area behind the muzzle.
All you need to do to apply your muzzle device using a lock nut is to apply the nut ahead of your device, and screw on the device after it. When the device is applied properly back the lock nut up to it and tighten the two together. The Lock nut and muzzle device will snug up against one another, creating a locking effect holding the muzzle device firmly in place. Some applications may require a bit of liquid thread lock.
The Custom Muzzle Brakes Muzzle Brake Lock Nut is finished in Mil-Spec black to blend into your build flawlessly. Made in the USA by American craftsmen, this hardened steel lock nut is the only retention accessory you’ll ever need.
