Vertical foregrips, which can trace their history back to the famous Model 1921 Thompson submachine gun, have recently leaped into prominence once again in military, law enforcement and civilian arenas. When attached to a compact, shoulder mounted tactical firearm they provide the operator with several important advantages from substantially diminishing muzzle climb during burst-fire sequences to simply offering a more comfortable shooting stance. With the recent introduction of the Surefire M900, a combination flashlight and vertical foregrip, the operator can acquire a product that fills both requirements.
However, not every agency or individual for that matter, can afford or justify the purchase of a large, expensive forearm assembly surrounded by multiple rail assemblies, when all they want to do is add a vertical foregrip or flashlight to the weapon. Over eight years ago, GG&G introduced an inexpensive Under Forearm Integrated Rail (UFIR) that permits instant installation and removal of a number of different vertical foregrips on the M16/AR15 weapon series, as well as flashlights and numerous other accessories. The GG&G UFIR can easily be installed onto the underside of an M16/AR15 foregrip, standard or M4, using simple hand tools and a small amount of Loctite 262. The three point mounting system insures a solid, rugged mounting platform. Installation does not require permanent alteration to the foregrip. Detailed instructions and all of the parts required are supplied in the kit. The UFIR is manufactured from 6061 T6 Billet aluminum, is Type III hard-coat anodized matte black per mil-spec and is machined to MIL-STD-1913 specifications. It is a lightweight accessory-only 1.6 ounces.
GG&G also offers a vertical foregrip for your use. It is CNC machined from a solid piece of black acetal polymer. This rugged vertical foregrip is 4.5? in length and 1.250? in diameter. The threaded core offers a secure and dry environment to store batteries or other small items.
