The officially licensed HERA Arms HFG Foregrip is built from ultra-durable fiberglass reinforced polymer and features a compact design that is both comfortable and functional. The grip securely mounts to picatinny/weaver rails and has a small internal compartment for holding small tools or batteries. The exterior is non-slip textured for maximizing grip and control.
This is a very great grip also is very comfortable. This grip fits nice to your rail with out any wobble and is also very compact. The compartment in the bottom of the grip is very nice and helpful for storing battery and tools.Riley
