The Arisaka Defense Offset Picatinny Adapter bridges the gap between modern handguard mounting systems and Picatinny-rail accessories. If you're running M-Lok, KeyMod, or CMR slots on your rifle but need to mount lights, lasers, or other Picatinny gear, this adapter solves that compatibility problem without forcing you into a whole new rail ecosystem. It's a straightforward solution: attach it to an Arisaka Offset Scout Mount or Side Scout Mount, and you've got a Picatinny surface ready for your existing lights and optics.
Built from 6061-T6 aluminum and hard coat anodized to MIL-A-8625 Type III spec, the adapter is tough enough for duty use and light enough not to throw your balance off. It's a slim 1.76 inches long and weighs half an ounce, so it tucks in nicely without creating a bulky setup. The design is CNC machined for precision fit—no wobble, no surprises when you mount critical gear.
This is a purpose-built piece of the Arisaka mounting ecosystem. You'll need one of their Scout Mounts (either Offset or Side, in M-Lok, KeyMod, or CMR) to use it, but once you pair them together, you've got a rock-solid mounting solution. Everything ships with the hardware you need—two 8-32x3/8" Torx flat head screws—and it's made in the USA.
