What you want more than recoil reduction is muzzle rise reduction. A couple ports on top of the muzzle device help tremendously.

Even so, I can put two rounds within an inch of each other at 25 yards or less, in less than half a second or so, with just a cheap muzzle brake like the Miculek design.
