Designed to mount behind a reflex sight or red dot to increase magnification, the Sightmark XT-3 Tactical Magnifier allows shooters to engage targets at further distances with a 23mm objective lens and 3x magnification. Compact and lightweight the Sightmark XT-3 features a flip-to-side mount, providing a rapid transition between your gun’s optic system, and 4” eye relief, improving overall comfort for shooters. External adjustments eliminate the need for tools for reticle alignment while fully multi-coated optics and rubber-armored housing increase the XT-3 Magnifier’s image clarity and durability. EOTech® and Aimpoint® compatible, the Sightmark XT-3 is quickly mounted and removed via a locking, quick detach mount.
