Built for stability and made of fiberglass-reinforced polymer to improve the impact resistance, the HFG front grip provides an internal storage place for storing items such as batteries. In relation to its weight, it is one of the most stable front grips on the market. It is compatible with MIL-STD-1913 rails. It can also be used on M-Lok systems when used in conjunction with Hera's M-Lok polymer rails.
