I do not have a brake on any of my 308s, but I did put a brake on my ar15 to settle it under rapid fire. I did a bit of research and found a brake that, while not the most effective at reducing recoil or muzzle rise, was among the best in a large side by side test but only cost $17 (at the time I bought it). they make the same brake for .308 (which I was sent accidentally the first time) the brake is available on amazon and goes by various names. to find it, search ".308 muzzle brake" and look for the one around $20 called "competition muzzle device brake". I cant say I would put one on a .308 bolt gun, but on my AR, I got it tuned to let me stay on target much easier for follow-up shots. it does howl like a banshee though.
