A muzzle brake has obvious benefits even on light recoiling rifles- but also negatives. I double up on the ear protection- but am not shooting at a public range so don't need to consider the way it impacts other shooters.

The APA and ultradyne have worked good for me... but also have a $30 AR stoner off of midway that does fine. I prefer side ports over the radial but both work and you don't need to time radial. The only real recommendation I'd offer is a self-timing.... so you don't need shims or a crush washer- and 2 or 3 ports seems to be the happy spot.
