Muzzle brake shims

Hello. I have a Sako TRG 22. I purchased and just received a suppressor and muzzle brake for it. I am not sure what size shims I need for the brake or where to get them. Any ideas? Thanks

 

Why do you need to "shim" the brake?

 

It's a thunder Beast compact brake and it has to be timed correctly.

 

By timed, I assume you mean indexed in a certain position so the ports are located in the right position. If so, try the Ace Hardware (or similar store) specialty nut, bolt, screw dept. They have an assortment of very thin machine & spring washers with various ODs & IDs. You will probably have to file to needed thickness or use more than one to get them to work. It's a trial & error fitting process. The other option is to have the shoulder machined so the brake indexes where you want it & never have to worry about the washers getting lost or damaged, which is what I would do. I use a spring washer (without modification) with my suppressors as it makes them easier to unscrew after extended use, but suppressors don't need to be indexed.

 

Thanks for the ideas. I'll probably try to have it machined so I don't have to worry about it

 

Many breaks use crush washers to enable correct indexing. If you plan to put it on and leave it on, a crush washer should negate the need to machine the barrel shoulder to suit the brake.
