These unique vertical pistol grips are 100% molded carbon fiber and weigh in at just 2.2 ounces. The grips themselves feature ambidextrous thumb shelves so they are suitable for either left or right handed shooters. Being lighter than any other pistol grip designed for airguns on the market, these help to shed weight at the rear of the rifle to improve overall balance. Our Carbon Fiber Vertical Grips are compatible with most airguns that accept AR-15 style grips. They come packaged with an included split washer and an external toothed lock washer that will need to be used on the factory grips screw to ensure that the grip has no play when installed.
