A slide-to-side mount engineered for use with holographic, collimated reflex and other compatible sight systems to provide shooters with the versatility of a reflex sight and scope in one. Use of the magnifier enhances target recognition and acquisition at medium range. Extended eye relief and a wide field of view team with high-quality, multicoated optics to improve visibility and image clarity. Slide it to one side when its 3X magnification isn’t required. Light, waterproof, fogproof and shatterproof frame makes it ideal for operations in any weather. Easily mounts on most Picatinny- and Weaver-style tactical rails and works well with EOTech, Aimpoint, Trijicon and similar reflex sights. Dimensions: 4.73" x 1.89" x 1.77". Weight: 6.7 oz.
