You love them or hate them it seems. The guy next to you at the range will love or hate it as well.
I've never seen a shooter positioned adjacent to someone shooting a braked rifle that loved the experience. Assuming your fellow shooters might appreciate being slammed with the pressure wave from your rifle is ridiculous at the very least.
IMO, a .308 Win doesn't warrant a brake. There are numerous options available to reduce the already fairly light recoil that won't generate so bloody much noise.
