The BT Rip Clip Paintball Loader for BT, TM-7 and TM-15 paintball guns is a great addition to those markers. The BT Rip Clip will slightly offset the loader to the side of the paintball gun, allowing for more visibility over the top of the gun. The Rip Clip Paintball Loader is based off of the Halo Paintball Hopper, a trusted and fast paintball loader!
