Great product...perfect for indexing muzzle brakes. Set it up once, and forget it. Saves time and frustration.
Makes clocking a brake a breeze

So much easier than a crush washer. The design is really nice also and doesn't look stupid if the jam nut's flat sides don't line up like other ones on the market that only have 2 flat sides. Decided not to use any loctite on this as I planned to test out some other devices. However even without any loctite it still hasn't moved after several hundred rounds. Easy on and easy off, simple to tune device. Great service from PA, but I am sure everyone knows they are one of the best companies to do business with! Always my first stop when shopping for parts.
