This Primary Arms MicroPrism is part of the SLx optics line. SLx optics have built a reputation for innovation, reliability, and value. All SLx optics undergo rigorous field testing during development to best serve you in any environment. For precision without compromise, the SLx 5x MicroPrism adds extended range to this lightweight, ultra-compact design. Weighing only 8.5 oz with a 3.31″ 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 distances than the 3x variant. Even in close quarters, the optic’s wide field of view and forgiving eye relief make it easy to snap on target.
