Putting clean white LED light alongside the hair-splitting accuracy of a green laser makes a lethal combination. The Sightmark® LoPro Mini Combo delivers both in a compact top or side mounting unit. This Class IIIa green laser and 300 lumen LED light can be mounted on a Picatinny or weaver rail of an AR-15, either in front of your rifle scope without interference, or on the side of the quad rail. The Tactical Light has 3 settings (low, full, strobe) that adjust with a simple twist of the bezel. The laser is offset to clear the front sight post and finger-adjustable windage and elevation knobs help you zero-in quickly.
