Perfect Solution
I ordered this Jam Nut for a Howa 1500 mini in 6.5 Grendel. I used it to clock the brake I wanted to install. It worked perfectly.

Jamb Nut Spacer
Installing a Area419 Sidewinder muzzle brake needed a quality .200 spacer on threaded rifle barrel. This jamb nut fit tight and flat with no change in shooting accuracy!

Obviously anything on Brownells I trust. This is the way to go when installing muzzle devices. Forget fussing around with shims. Do a YouTube look up and confirm how easy jam nuts are to use. Installed my suppressor adapter in 15 seconds! High quality threads and finish.

Works great
Ordered a precision armament brake and a shim kit. While the shim kit worked it took forever to get the correct timing on the brake. I didn't really like the look of it. This JP jam nut was faster and looks better in my opinion. Would buy again.
