AOK | Surefire X300-B Offset Key

The ATLAS AOK (Offset Key) is an enhanced rail key designed to improve weapon light positioning by shifting the Surefire X300-B rearward for a tighter, more intentional fit.

Many setups especially on the Ruger 22/45 platform leave the X300 sitting too far forward, creating unnecessary gap and inconsistent alignment. The AOK corrects this by bringing the light back into a more natural position on the rail.

Manufactured from durable PA12, the AOK is lightweight, impact-resistant, and built for consistent fitment.
