Arisaka Picatinny ARMS 17S Rail Slider Bipod Mount

The Arisaka Defense Rail Slider is a Picatinny-mounted support adapter built around the A.R.M.S. 17S pattern used by many bipods and shooting-support accessories. It lets a compatible support move along the rifle rail without requiring the entire accessory to be removed and reinstalled at each position. The sliding arrangement is especially useful when the preferred support point changes between prone, barricade, bench, or tripod-supported positions.

A push-button recoil lug and adjustable sliding tension allow the base to move when desired and then clamp down firmly for use. The 17S interface supports compatible bipods and adapters, while the Picatinny base keeps the system centered on a standard rifle rail. Because rail dimensions and accessory footprints matter, confirm that the rifle rail is in spec and that the attached support uses the A.R.M.S. 17S pattern.

The Rail Slider is more than a fixed bipod stud because it gives the shooter a controlled way to reposition a support along the rail as the firing position changes. It also provides a common mounting point for compatible bipod and tripod accessories built around the 17S footprint.
