Cost-Effective Way To Mount A Vertical Foregrip, Flashlight, Or Other Tactical Accessory

The GG&G UFIR Under Forearm Integrated 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. It has a three-point mounting system that ensures a solid, rugged mounting platform.

Vertical foregrips and other accessories mounted at the 6 o’clock position on shoulder-fired weapons have become prominent in military, law enforcement, and civilian. This under forearm rail mount will allow the installation of accessories such as flashlights, lasers, and vertical grips that attach to a Picatinny-style rail.
