The BT-4 ERC™ comes standard with the BT Electronic Grip Frame and BT Rip-Clip™, which allows you to experience the fastest possible rate-of-fire. The Rip-Clip also features a built-in rip drive. The innovative BT Rip-Clip™ force-feed loader system mounts easily onto any BT-4 marker. Simply remove the standard feed elbow, slide on the Rip-Clip, align the feedport and secure with the thumb screws. If you have a need for speed, this is the marker that delivers.
