Just for reference in case anyone is wondering how it fits up against the Daniel Defense RIS II on a 10.3" barrel. The armorer (Robb Jensen from ESS) used a thicker washer from a Surefire kit just because he was concerned about the clearance. The muzzle device is a Griffin Hammer Comp.

Pure sex. You know, the YHM QD mount is a solid piece of gear but it just looks fucking goofy. I wouldn't care if it were an issued gun/agency purchase since functionality is all that matters in that case, but this is a personal gun, and this is like thigh-gap on a chick in a bikini but for gun nerds.

Anyways, just thought I'd share for the sake of reference.
