Very cool laser for your ar - Viridian OpticsPlanet Exclusive HS1 Laser Hand Stops

The first one I purchased didn't work. Optics Planet made the return super easy and before I knew it I had a new one delivered. The laser is extremely bright and visible. It installs fairly easily on your M-lok rail but I recommend adding a drop of locktite to both bolts to avoid it rattling loose. This is exactly what you need for your AR especially for home defense. Great if you want to shoot from the hip, just point the laser on your target and pull the trigger. No awkward on/off switch, just grip it and the laser turns on.
