Viridian’s new HS1 is the world’s first AR hand stop with an integrated laser sighting device. Featuring M-Lok mounting, grip activation buttons, adjustable windage and elevation, and an ergonomic design, the HS1 is the ideal accessory for your tactical firearm. The uniquely positioned pressure-activated button makes the HS1 perfect for use on AR-style firearms, as the laser can be activated regardless of grip style. The shooter benefits from the protection of a hand stop while using a highly visible green laser sight for aiming.
