The X7 M-16 Foregrip is a free-floating grip that attaches securely to your marker without the use of set screws, compression rings or adapter sleeves that can damage your barrel. As a member of the comprehensive family of X7 mods, the M-16 foregrip is an interchangeable grip made from extremely resilient glass-filled nylon composite with an integrated aluminum hub, so its one-piece construction is capable of withstanding the intense demands of repeated woodsball play.
