Straight Shot Gunsmithing
another good one : Defensive Edge ... Covering your 6
A baffle style brake usually has slots cut in the sides. No holes on the pottom. Some have a small hole or two on the top as well to reduce muzzle jump. The BOSS on the other hand is like a sieve, with holes everywhere.
I don't personally see the noise as an issue. You will never shoot it at the range without ear plugs. Only perhaps 1 in 4 hunting situations don't allow time to put in ear plugs. Frankly, I never bother with ear plugs while hunting. I don't find the noise of 1-3 shots bothersome.
Freebore has a good point about it being something of a collectors piece. Although Winchester is basically back. I don't personally think a nice brake would detract from it's value. But, something to consider...
