Biggest difference is in flash reduction. The Surefire puts out a huge bright flash to front and sides, and the MAMS makes a small muted ball similar to, but larger than a KAC 3T. I've shot it in a class and none of my classmates griped about the concussion like they do with the MB556K. It also brings my barrel length to about 16.2 inches when P&W'd.
