Flash hiders/muzzle devices affect on accuracy?

Good points, StoneHendge. Before my Grendel I had a few 5.56 rifles with the standard A2 style bird cage on, didn't do much to keep the gun steady in prone and it did move my scope a bit when I would shoot for distance (Nothing exceptional, out to 300 yards or so at the most).

Thanks for the response Klem, that's a handy data table you posted. If you don't mind me asking, what brake did you go with? I'm content sticking with the Warcomp, as it suppresses flash and tames recoil exceptionally, but I am open to any and all suggestions.
