GG&G AR-15 UFIR Direct Thread Picatinny Rail 4.5"

Not every rifle needs a quad rail. The GG&G UFIR (Under Foregrip Integrated Rail) adds one short Picatinny section at the 6 o'clock position of an AR-15 forearm, which is all you need for a vertical foregrip, flashlight or bipod.

This direct thread version is 4.5" long and machined from aluminum. It sits very low, installs with hand tools, and uses a three point mounting system to stay put.
