GG&G AR-15/M16 UFIR Under Forearm Integrated Rail 1055 not only meets all military standards, but is also the most cost effective way to mount a vertical grip, flashlight, or other accessory to your AR-15's fore end. The inexpensive but mission ready GG&G Under Forearm Integrated Rail permits instant installation and removal of most vertical foregrips, flashlights and numerous other accessories on the AR15/M16 weapon systems. The GG&G UFIR AR-15 Bottom Adapter Rail can easily be installed onto the underside of an AR15 or M16 forearm (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. Because this handguard rail mount follows the Picatinny Rail (MIL-STD-1913 or NATO's STANAG 2324) standard you will have no problem with accessory compatibility. Installation of this GG&G Rail does not require permanent alteration to the forearm. GG&G supplies detailed instructions, and all of the parts required are supplied in the kit. The UFIR is manufactured from solid 6061 T6 billet aluminum alloy and is Type III hard-coat anodized matte black per mil-spec to provide combat durability. The GG&G UFIR is four inches long, provides eleven mounting cross lugs and machined to MIL-STD-1913 specifications so as to provide tactical flexibility in accessory mounting. If you or your agency can't justify the cost of a forearm assembly surrounded by multiple rails when all you need to do is add a vertical foregrip or flashlight to the weapon, the GG&G Botton Fore End Rail is for you!
