GG&G UFIR Handguard Rail (Under Foregrip)

The GG&G UFIR (Under Foregrip Integrated Rail) provides a compact MIL-STD-1913 dovetail mounting option for the lower handguard of AR-15/M16 rifles. It installs into the vent holes of the lower handguard without removing the handguard and requires no backing bushings, nut-serts, or other fasteners. The integral camming attachment system allows installation and removal with a flat tip screwdriver and avoids alteration to the handguard. Constructed from 6061-T6 aluminum with a Type III hard-coat anodized matte black finish, the UFIR is a lightweight, durable solution for mounting lights, bipods, and other accessories.
