The tactical weapons community loves muzzle brakes. The problem with muzzle brakes is that most of them require correct timing to function properly and that part of the relationship can be a little strained. Crush Washers, Peel washers, and shims are all used to time and solidly mount muzzle devices to varying degrees of success. Some of them can be downright maddening when you need to remove a muzzle device. JP Enterprises offers a solution to all the hassle that those devices cause, the jam nut for muzzle brake. The JR Enterprises 1/2-28 Muzzle Jam Nut takes the hassle out of muzzle device installation and allows you to remove them with less hassle than other mounting methods.
Choose One to Match Your Build
Whether you prefer Mil-spec black or bright stainless components, JP Enterprises offers a 1/2-28 nut to work with your build. Choose your AR15 jam nut in clean stainless steel or with a magnesium phosphate finish. Either way, you get a quality muzzle jam nut that gives you an easy to time, solid mounting option for your threaded muzzle device.
Brake Installation Made Easy
Brake installation using a jam nut for muzzle brake is an easy operation. Thread the jam nut on your barrel first, then your muzzle brake. When the brake is installed at the proper timing, the jam nut should be tightened against it. The locking effect of the two parts against each other will secure the brake in place. The best part is if you change your mind, or your timing is a little bit off, you can loosen the jam nut and brake and 1/2-28 nut remove or start over and get it right without requiring an act of congress or another wait for the mailman.
