I like many guys read through all of the muzzle brake shootout test and ended up buying a Precision Armament M4-72 severe-duty brake. The thing is absolutely miserable to shoot, a large amount of concussion and gas comes directly back towards shooter, not to mention a huge fireball. Someone I was shooting with suggested getting an adjustable gas block, so I did (Seekins at 2 turns out) but it was no help, the front 4 inches of my handguard are brown from it. This thing has got to go.
So what are people running that don't make shooting unpleasant but gives a major recoil reduction?
