Works great 02/06/2018
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.
WOW 21/10/2017
These are great. No more vise blocks to remove the barrel device. No more put it on, take it off to clock it. Uses a 3/4 wrench so it is the same diameter as my flash hider. Has a nice matte finish that did not scratch during install on 3 rifles. I will be getting some in 1/2" soon. You will not be disappointed.
