The TacFire Slim Float Handguard (TacFire part no. HG26-4) is a 4-inch free-float M-LOK handguard machined from 6061-T6 aluminum, giving AR-15 builders a lightweight, slim-profile fore-end for short-barrel or pistol-length builds. A full-length Picatinny top rail runs the length of the handguard for co-witnessing sights or mounting optics, while M-LOK slots on the remaining sides give you direct-attach points for lights, lasers, and foregrips. TacFire finishes the handguard in a Type III Class 2 hard-coat anodized black finish, which stands up to the wear and corrosion that come with regular range use.
