Viridian HS1 Features The Viridian HS1 combines a traditional AR hand stop with an integrated red laser sighting device giving shooters a dual purpose accessory that reduces weight and frees up valuable rail space compared to running separate components. Grip activation buttons let the shooter turn the laser on naturally as they establish a firing grip working across a variety of hand positions and grip styles common on AR-style rifles. Adjustable windage and elevation allow the laser to be zeroed precisely to the point of impact and the wide angle peripheral beam helps the shooter see more of the surrounding environment in low light. This combination of ergonomic design and integrated aiming support helps improve recoil control and maneuverability during dynamic shooting. Mounting to a Picatinny rail the HS1 installs easily on most AR-style rifles already equipped with a standard accessory rail. Powered by a CR1/3N battery with an estimated 1.5 hour run time the polymer-built HS1 is finished in black to blend in with most rifle builds. Its resistant waterproof construction holds up to field conditions while the pressure activated button design makes it ideal for shooters using a variety of grip styles under stress. For AR owners who want the protection of a hand stop along with the fast target acquisition benefit of a laser sight the Viridian HS1 is available for sale at GrabAGun.
