Bolted right onto mossberg 930 jhm pro - Nordic Components Picatinny Rail for Barrel Clamp

Perfect way to attach a light to my Mossberg 930 JHM Pro. Found out the barrel clamp this is compatible with came stock on my shotgun and purchased this to throw a picatinny light on. Fits snugly against the barrel clamp. Screw and threads matched up perfectly. Rail was a exact match to the picatinny light mount. I put blue loctite on the screw and it hasn't backed out in several boxes of bird shot and a couple tubes of buckshot.
