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 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.
