These grips are the lightest grips ever made for the AR-15 platform. No other grip offers superior versatile ergonomics and strength in such a lightweight and stylish design. Future Forged SG series grips utilize design principles inspired by the aerospace & exotic materials industry. The Vektor SG's unique design achieves a surprisingly high strength to weight ratio when compared with traditional molded polymer or machined metal grips. The SG-1 grip features a longer front pommel and a rear tail for added maneuverability. While the SG-2 has a more compact outline for maximum weight savings and anti-snag shape. Product weights: SG-1 styles are 1.3 oz, SG-2 styles are just 1. Mfg: Future Forged Ltd
