The Viper Ergonomic Fore Grip was developed using innovation and feedback from combat veterans. This grip is made from advanced polymer which is very strong and will definitely take a beating. The shooter can use different grip techniques and still have a secure and comfortable grip in any situation or position. It features a ridged front face that allows you to brace the rifle against a table or a wall. Because it is ridged, it will prevent any sliding during the recoil kick. Another unique feature is the Viper hood. It acts like a heat shield that will prevent the heat from going to your hands and gives your lead hand an ergonomic platform to use. The rear portion of the Viper Grip can function as a hand stop. One advantage that the Viper Grip has over its competitors is the friction lock design. Material has been removed from the center so that when tightening the Main Screw during installation, the grip will form to the rail system. This prevents wobbling due to loose fitment or overuse of the grip. The Viper Fore Grip is slim and low profile, which makes it very lightweight. It is very ergonomic and economical.
