These foregrips are compatible as either a Keymod angled foregrip or M-Lok foregrip thanks to the patent-pending LINK system from Strike Industries. The innovation doesn't stop there, this AR 15 foregrip is designed to be adaptable to almost any kind of scenario. The front face is ridged to allow extra stability when bracing the rifle. The rear curve allows it to be used as a handstop in addition to being a completely functional AR 15 forward grip. Instead of plastic, these are durably built out of billet 6061T6 aluminum, keeping them lightweight but tougher than many of the others available on the market today. The variety of colors, including black or FDE, allow you to match the AR foregrip to your rifle's current finish, or make it stand apart with the red or blue options.
