Available in Red/Carbon Black or Blue/Carbon Black. These grips are additively manufactured using premium Engineering grade Carbon Fiber reinforced polymer. The unique internal compound lattice structures of the SG-1 & SG-2 grips enable these unique grips to be almost 80% air on the inside. No other method of manufacturing can construct a grip like this. Typical weights are 1.3-1.6 oz without screw. Which is a full half ounce lighter than any other production grip ever made. This makes Future Forged second lightest type of grip. Like all Future Forged Grips, the inside features a complex structure similar to what you would find in advanced aerospace materials. No injection molded type grip can achieve this level of strength to weight ratio. The lines that are present from the additive manufacturing process are designed to increase grip with both gloves and bare hands. Compared to “skeletonized Aluminum” grips that freeze your hands in the wintertime these Carbon and Glass fiber polymer grips help keep your trigger hand warmer in the winter when the shot really counts! Ditch the boring and heavy old “blob of rubber” grips or expensive machined skeletonized metal grips that scratch easily and freeze your hands in the cold. Get a Future Forged Hybrid carbon fiber polymer grip and make your AR rifle or pistol stand out!
