People pay me to install them and I try as best I can to talk them out of one.

There are too many other good alternatives to a muzzle brake that help tame the felt recoil with out making yourself deaf in the process.

I was once four benches down from a guy firing a 30-378 out of a MK-V with a brake on it and even with hearing protection it would make me jump a little bit. The muzzle blast is almost unimaginable with some cartridges. What's really funny is he bought the gun specifically for the purpose of a black bear hunt. I asked him how long of a shot he would have and his reply was he was hunting over bait so he expected 75 yards or less. A 30-30 would have been just as effective at that distance.

Basically, if it kicks hard enough that you need a brake to shoot it then sell it and buy something that kicks less.
