The Promag PM007 AR-15 vertical foregrip attaches to forend rails, quad-rail forends or any Picatinny rail on an AR-15 or M16-pattern rifle. It is a Swiss-pattern vertical grip that gives your support hand a natural hold and puts weapon-mounted lights, lasers and other accessories within easy reach. The grip is made from injection-molded, Zytel-based black polymer. It needs no tools or extra hardware to install. Features: Swiss-pattern vertical foregrip for AR-15 / M16 rifles Fits forend rails, quad-rail forends and any Picatinny rail Injection-molded, Zytel-based black polymer No tools or hardware required Natural support-hand grip for operating lights and lasers Mount it far enough forward to clear your magazine well during reloads, and make sure it locks fully into the rail slot before you shoot. Legal note: Under federal law, adding a vertical foregrip to a handgun, including an AR pistol, can make it an "Any Other Weapon" (AOW) under the National Firearms Act. Install it only on a rifle unless the firearm is registered for it, and check your state and local laws.
