They shim your barrel device.

Does the job. Used the different shims to get my muzzle device straight. Recommended.

Yes they are shims. Yes they will help get your device clocked. They seem over sized a bit. The edges stick out a bit from the barrel and they are sharp.

Much better than crush washers. You can use the different thickness washers to dial-in the perfect tune.

This is a good kit. It allowed me to time my compensator. I wish it had some thicker washers so I didn't have to use so many but I don't expect to be taking it off and on much so it's really not a huge issue.

If you need to get that muzzle device tight and oriented just right, then a set of shims like this are just what you need. Easy to mix and match to get things lined up just right.
