I've got a Bushmaster Y-Comb on my AR and it works but the thing is LOUD!!!  Is there a brake I can put on there I can coyote hunt with, without bursting my eardrums?  I don't want the bare muzzle nuetered look.

Bushmasters catalog lists quite a few types of brakes and supressors.
I take it you have a preban rifle,i`m stuck with
a postban bush with the same brake on it and i hate it. Looks like it will be exspensive to change mine.

Any brake that is effective, and that is the point of a break, is going to be loud.  The louder it is, the more gas that is being redirected lessening the recoil. I have shot the y-comp and is it damn LOUD, but it does make follow up shots much easier on a lighter weapon. No matter what you will have to spend some cash to have it removed and a bunch more to have a new one installed.  Just think, if we did not have this pre-post Bravo Sierra you could just unscrew it and try a different one (although it would most likely be an FS).
