The Sightmark Tactical Magnifiers increase the magnification of accompanying sights for greater sighting range and improve target recognition significantly from medium-range to long-range distances. Engineered to assist in quick target acquisition, magnifiers are offered in a variety of models including 3x, 3x Pro, XT-3, 5x, and 7x. All models are weatherproof to handle variable conditions, while the XT-3 is currently the only model that is fully waterproof. Sightmark Tactical Magnifiers feature a lightweight, shatter-proof frame that provides durability in the field.
