Overview

Designed for standard KeyMod handguards, this light mount offers a secure way to position a tactical light without removing the mount from the rail. Its vertically anchored ring system comes in two sizes, giving it compatibility with light bodies from 0.84" to 1.03" in diameter. The offset layout is intended to help maintain clearance with most front sights, making it a practical option for rifle setups that need both illumination and unobstructed sight use. At 1.0 oz., it keeps the mounting solution compact while still allowing easy light installation and removal.

Pros

  • Vertically anchored ring system provides a secure attachment method.
  • Two ring sizes accommodate a wide range of light body diameters.

Considerations & Trade-offs

  • Fits standard KeyMod handguards, so it is not a universal solution for other mounting systems.
  • Light-body compatibility is size-specific: the large ring fits 1.00" to 1.03" bodies, while the small ring fits 0.84" to 0.88".
  • The offset placement is designed to allow clearance with most front sights, but compatibility still depends on the specific light and sight setup.
  • A light can be installed and removed without removing the mount, but the ring-based design requires matching the correct ring size to the light body.
