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:
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.
