The Arisaka Defense Rail Slider takes a standard 1913 Picatinny rail and turns it into something far more useful: a multi-position sliding mount that lets you move your bipod exactly where you want it without fighting slot spacing. Instead of being stuck to fixed rail notches, you slide the mount to your ideal spot, drop the push-button recoil lug into place, and you've got a repeatable, solid seat. It's a simple idea executed really well, and it's the kind of upgrade that quietly makes a precision setup easier to run.
The detented tension knob is the star here. It sets how freely the mount slides, and because it adjusts clamp tension, it'll happily grip rails that run a little out of spec instead of leaving you with a loose fit. That same knob lets you open the clamp and drop the slider onto (or off of) the rail without sliding it past the end, which is a genuine time-saver on longer rifles or when you've got a hand stop or other static gear already mounted up front. Snug it down when you want everything locked for accuracy.
Built around the ARMS 17S pattern, the slider works with the bipods most precision guys already own: the Atlas PSR, Atlas CAL, MDT Cyke, and Magpul 17S all drop right on. Running a Harris swivel bipod? Add Arisaka's 17S Harris adapter and you're set. There's also a whole ecosystem behind this thing, including tripod ball head adapters and barricade stops, so it grows with your kit.
This is CNC-machined from stainless steel components paired with MIL-A-8625 Type III hard coat anodized 6061-T651 aluminum, and it's made in the USA. At roughly 2.2 ounces it adds almost nothing to your setup. Installation is straightforward with the two included 10-32 socket cap screws, a 5/32 Allen wrench, and about 30 inch-pounds of torque. If you shoot off a bipod and hate hunting for the right rail slot every time, this solves the problem for good.
It uses the ARMS 17S pattern, so it directly fits the Atlas PSR, Atlas CAL, MDT Cyke, and Magpul 17S bipods. If you run a Harris swivel bipod, you can add Arisaka's 17S Harris adapter to make it compatible. That covers the vast majority of precision bipods out there.
Yes, installation requires a 5/32 Allen wrench, which is not included. Use the two 10-32 socket cap screws that come in the package and torque them to about 30 inch-pounds. Once it's on your bipod, adjusting position on the rail is done by hand with the tension knob.
That's one of the best parts. By opening the clamp with the detented knob, you can install or remove the slider directly onto the rail without sliding it off the end. This is a real convenience on longer rifles or when you already have a hand stop or other static gear mounted up front.
Yes. The detented tension knob adjusts the clamp, so it accounts for rails that run slightly out of spec instead of leaving you with a sloppy fit. You can dial in the sliding resistance you want and then tighten it down for a locked, precise hold.
