The Arisaka Rail Slider with ARMS 17S Interface (brand part no. RS-BASE) transforms a standard Picatinny rail into a multi-position sliding mount with a push-button recoil lug. A detented knob sets the sliding tension, compensates for out-of-spec rails, lets the mount be installed or removed without sliding it off the end of the rail, and can be quickly and firmly tightened down for maximum precision when it’s time to shoot. Built around the ARMS 17S pattern, it’s compatible with popular bipods including the Atlas PSR, Atlas CAL, MDT Cyke-Pod, and Magpul 17S Bipod. Arisaka CNC machines the slider from stainless steel and MIL-A-8625 Type III hard-coat anodized 6061-T651 aluminum, and it includes two 10-32 socket cap screws.
