Product Summary

The Arisaka Ring Light Mount provides a flexible yet secure way to attach handheld lights to your handguard. Available for KeyMod, M-Lok, and CMR interfaces, it uses a vertically anchored ring system that comes in two sizes to accommodate a wide variety of lights.

The clamping ring will accept light bodies with a diameter from 1.00″ to 1.03.” A light can be installed and removed without having to take the mount off your handguard.

The offset placement of the light while using the mount is designed to allow clearance with most front sights. For example, a 1.03″ light like the Surefire G2 will work with the Magpul Gen 2 MBUS on a Noveske NSR, which is one of the thinnest handguards at 1.48″ wide.

  • Weight: 1.0 oz.
  • The mount is CNC machined from 6061-T6 aluminum
  • MIL-A-8625 Type III hard coat anodized.
  • Requires a 3/32″ Allen wrench for installation (not included).
  • Made in the USA.
