There a number of effective brakes out there, and most of the good ones have similar design. Although it's kind of large, the Badger FTE brake works well. The MSTN/PRI "QC" comp is also effective. The various JP brakes work well but are very loud. I prefer the brakes that do not require a torque spec to "time" because they are easier to remove and replace (e.g. for cleaning) and the only one I'm aware of besides the proprietary AI brakes is the FTE. There are a lot of other brakes available for bolt rifles, and I'm not aware of many of them. Just about any competent gunsmith with a lathe should be able to thread the muzzle and install a brake.
