This scope features a tubeless design with 33mm reflex lens aperture which gives the user a wider field of view - Great for those CQB situations. Another cool feature is the Multi-Reticle & Green/Red Color Option.
BATTERY Your sight is powered by 3x LR41 cell batteries. Should your reticle grow dim or not light, you will need to replace your battery. To install battery, unscrew battery cover and insert the new battery + side up, and replace the cover.
** THIS SIGHT DOESN'T COME WITH BATTERIES**
MOUNTING Your sight includes an integrated rail that fits standard, dovetailed bases. This is suitable for most application. Set the rail onto the base so that the rail claw aligns with the crosscut grooves. Work the claw into the base until the cross-bolt seats into the groove. Secure the locking screw with an allen wrench included with the sight.
