The sound will be greater to the shooter with either the flashhider, or muzzle brake as gasses from both are vented up, and out, so is the sound.
If your going to cut your barrel, the muzzle brake probably won't improve the accuracy anymore than the flashider, as cutting stiffens the barrel, but it would help with muzzle jump. If you arn't going to cut the barrel, a brake will probably help accuracy more. A lot of members use the BW double muzzle brake, same as the John Mason. Cost $19.95, and we install it ourselves. Pins over the front sight.
Either way if you have open holes or slots in the bottom, and shoot in the prone position, you may get blasted with sand, and dust.
