Great device - ODIN Works ATLAS Compensator

works as advertised really cuts down on the muzzle rise for fast follow up shots. you don't want to be on the side of the muzzle when this thing goes off lots of blast wave but for the shooter it's great! simple easy install love not dealing with a crush washer and timing this device, didn't even need to adjust after the initial install, however some of you may but so simple you couldn't ask for anything more.
