X400U-A-GN) pairs a 1000-lumen LED with a green laser in a single gun-mounted unit from Surefire, built to fit Picatinny, Weaver, and Glock accessory rails without an adapter. Running the light and laser together gives a shooter both target identification and a fast aiming reference from one activation point.
