Great brake, terrible shim kit - Rugged Suppressors 7.62 3 Port 5/8 X 24 Muzzle Brake

The brake itself is fine. The quality and finish are fantastic. I'm taking away one star because the shim kit is completely useless. Because this is a suppressor mount brake, it needs to be shimmed instead of using a crush washer, but the shims that come with the brake only come with 3 different size shims for which the smallest adjustable angle is 30 degrees. So basically if your barrel threading isn't timed exactly correctly, you can't get the brake timed correctly (my barrel threading made it so my options were either 5-10 degrees too far past the correct timing or 20-25 degrees short of the correct timing). Additionally, even if you are able to get the shims to time the brake correctly, the outside diameter of the shims is so much wider than the brake that you can't get an armorer's wrench onto the brake to give it the last little bit of torque needed because the shelf on the brake for the armorer's wrench is so short.

Now I am left to buy a different shim kit before I can correctly install the brake. More money and more time waiting. I have never had this issue with my Lantac Keymo mount brakes.
