Recoil is basic physics. The easiest way to reduce recoil, or minimize the effect, is to either add weight to the rifle, or use a muzzle break. Whether or not you want to add weight to your rifle depends on how you use it. If you shoot from the bench, additional weight is not a problem; you can add a buttstock weight or weights under the hanguards. If you use your rifle for more tactical shooting, a muzzle break is preferable. I believe the one you are describing is the Y-comp/Mini Y-comp from Bushmaster. It is a very efficient break and does an excellent job of keeping the muzzle down and reducing felt/perceived recoil although it increases muzzle blast. If your rifle is a Pre-ban, you might consider a silencer. The silencer works the same way as a muzzle break(redirecting gas) to reduce recoil and elimates the muzzle blast. Keep in mind that unless your using sub-sonic ammo that the .223 will not be quiet. IMHO your best bet is to get some professional instruction. You state that you have trouble controling the Bushmaster with an AK break. The .223 has very little recoil in a semi-automatic rifle, and with a muzzle break(AK,Y-comp,Levang) has almost none. This leads me to believe that the problem may have as much to do with technique as with recoil. Please don't take this wrong, just trying to help.
