Frequently Asked Questions

What tools are needed to install an Olight OSight XR on a Glock 45 Gen 5?

You'll need a sight pusher tool (like Wheeler Engineering's) for the iron sights, and a torque wrench (like the Wheeler F.A.T. Wrench) to properly tighten the optic mounting screws to the manufacturer's specifications.

What are the benefits of suppressor-height sights with a red dot?

Suppressor-height sights provide a lower third co-witness with a red dot optic. This means if your red dot fails, you still have functional iron sights visible through the optic window for aiming.

How bright is the Olight PL-X weapon light?

The Olight PL-X weapon light delivers a powerful 1,200 lumens of output and has a throw distance of up to 300 meters, making it effective for target identification in various lighting conditions.

What reticle options does the Olight OSight XR offer?

The Olight OSight XR features switchable reticle options, allowing users to choose between a precise 2 MOA dot for focused aiming or a 32 MOA circle for faster target acquisition in dynamic situations.
