The ARCA Rail Grabber is a tool-less push-button adapter designed for the Spuhr SICS forend. To attach accessories, the Rail Grabber has an ARCA Swiss interface in addition to a Spuhr Interface. An ARCA bipod/tripod can be attached directly, or a short Spuhr picatinny rail can be mounted to the Rail Grabber. The Arca Rail Grabber can be rapidly – and securely – moved between positions along the Spuhr SICS rail. With a push of a button, the grabber releases a set of pins to allow movement along the rail. Once the button is released, the pins will lock into the desired position on the rail.
