Sightmark T-5 5X Flip Magnifier 23mm Matte Black

The Sightmark T-5 is a 5x magnifier that mounts behind a reflex sight or red dot to provide an absolute co-witness and extend effective engagement range. The unit uses a flip-to-side LQD mount to let shooters switch quickly between 1x and 5x while keeping a low, snag-resistant profile. Constructed from aluminum, the T-5 is IP55 water resistant and rated shockproof up to .308 caliber rifles, and its fully multi-coated optics improve brightness and resolution.
