I've never felt the need to tame any recoil on a .223/5.56 rifle. That being said, I put flash reduction as the main priority when choosing a muzzle device. There are many options out there as I am sure you know. I have always preferred the Yankee Hill Machine "Phantom" myself. While it might not be quite as good as the Vortex design, I do like the looks better and it does work quite well.

My 2 cents.
