Light Mount Compatibility & Fitment Guide

 

Choosing the right mount is essential for ensuring your weapon light sits tight to your rail and clears your iron sights or laser aiming devices. Use this guide to determine if our Arisaka Offset M-LOK Mount is right for your setup.

1. Does it fit my light?

The Arisaka Offset Mount is designed for "Scout-style" light bodies. This means any light that features the industry-standard two-hole mounting interface on the base.

• Cloud Defensive: All REIN® series (including Micro and 3.0).

• SureFire®: Scout Light® series (M300, M600, M640 Note: Pro models require the removal of the swivel mount).

• Modlite: All PLH and OKW handheld-to-weapon light bodies.

• Streamlight®: Protac® Rail Mount 1, 2, and HL-X.

• Arisaka: 300, 600, and 18650 Series.

2. Does it fit my firearm?

To use this specific mount, your firearm must have an M-LOK compatible handguard.

• Placement: This mount is an "Offset" design. When mounted to the 3 o'clock or 9 o'clock M-LOK slots, it will cant the light at a 45-degree angle, tucking it into the "corner" of your rail (the 1:30 or 10:30 position).

• Clearance: Because the mount is ultra-slim (0.20” thick), it is designed to clear most top-rail mounted laser designators (like a PEQ-15 or DBAL) or backup iron sights.

3. Critical Installation Notes

• Torque Specs: * Light-to-Mount: 20 inch lbs (with a drop of blue Loctite).
