Built for shooting versatility, the SightMark T-5 is a magnifier that mounts behind a reflex sight or red dot and provides an absolute co-witness. Instantly change the magnification of your close-range optic from 1x to 5x by using the T-5's flip-to-side mount. The streamlined low-drag design of these Red Dot Sight Magnifiers prevents them from snagging on clothing and equipment. Ideal for stretching your AR engagements out to 200 yards, an included LQD mount allows for rapid attaching/detaching in intense shooting situations. The T-5's aluminum construction is shockproof up to .308 caliber rifles and provides IP55 water-resistant protection. Brightness and resolution are improved from fully multi-coated optics, and external windage and elevation adjustments help shooters align the reticle of their red dot/reflex sight to the center of the magnifier's point of view. The Sightmark T-5 includes flip-to-side LQD mount adjustment tools and a manual.
