For precision without compromise the SLx 5x MicroPrism brings an extended range to this lightweight ultra-compact design. Weighing only 8.5oz with a 3.31in overall length the SLx 5x MicroPrism is comparable to many red dot sights though its crystal-clear glass and 5x magnification offer improved precision at even longer distance than the 3x variant. Even in close-quarters the optics wide field-of-view and forgiving eye relief make it easy to snap on target.
