The Crimson Trace MVF-515R Foregrip is an innovative advancement in weapon technology that combines a dedicated tactical foregrip, an aim-improving red laser sight and a 150/200-lumen LED light to produce a new standard in shooting accuracy. The laser and light operate on Crimson Trace's popular pressure-activated switch, which turns on instinctively as the weapon is gripped. The master switch acts to turn off either component if desired. The laser is factory sighted to show a 0.5-inch dot at 50 feet and can be easily user-adjusted for windage and elevation. Because it is a modular rail attachment, it features an ambidextrous activation switch and can accommodate a separate green or infrared laser if required.
