With due respect, if you're having the issue using the Miculek brake, I question how much any brake is going to solve your problem. The Miculek brake is pretty aggressive reducing recoil - more so than a BattleComp (which I use pimarily). Something ported on the top and closed on the bottom will reduce the muzzle flip, which the BattleComp does quite well. The main thing is to be behind the gun squarely and solidly. If you're shooting offhand, that means shoulders squared up to the target, dominant shoulder rolled forward slightly and weight forward to drive the gun. If your shooting prone, get as square as possible, again with dominant shoulder rolled slightly into the gun driving it. At matches, it's often hard to be optimally positioned to manage recoil most effectively, but the AR-15 is pretty forgiving. My guess is that you are somewhat bladed in your position and the muzzle flips up and to the right. On my match rifle, I time the brake a little off-center to counter this tendency. (This only works with a brake with closed bottom and ported top.) Overall, I like the BattleComp, especially if you are shooting from an odd position on the ground like urban prone. The Miculek brake and others like it will excavate a hole often blasting dirt back into the face, which the BattleComp won't do. The BattleComp, on the other hand, does not reduce felt recoil quit as much, but is almost as effective. Good luck!
Edit: Also, if you shoot at night, the muzzle flash with the BC is almost nil. The Miculek, Surefires and such will produce spactacular fireballs!
