Works great on the DPMS Oracle kit AR that I built - just the right height and length for that funky gas block mount DPMS uses. Screws on easily by hand, but you'll definitely want to tighten it down further with an actual screwdriver to keep the thumb screw from backing itself off. Holds zero for 50 yards just fine, although the front sight post is wide enough that it almost blocks out a 6" target at that distance or anything farther. Would have been a nice bonus if this included a front sight post adjustment tool, as I wound up having to crank mine down about two full turns, but one could probably get by with using an empty .223 brass casing or something else to push in the little detent pin. All metal, too, so no worries about melting from the heat from the gas block where it's mounted.
