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 magnifiers streamlined, low drag design prevents it from snagging on clothing and equipment and makes the T-5 .7 shorter than the magnifier its replacing. 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-5s 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 magnifiers point of view.
