PRO MAG AR-15/M16 FLIPUP A2 REAR SGHT-

The PM202 M16/AR-15 A2 rear sight can be used as a co-witness iron sight with most red dot and holographic sights or, as a stand-alone sight. Weighing in at just under two ounces, it features the standard military A2-style double peep aperture which allows for a known point of impact. The sight is low profile so that when in the down position, it will clear most optics. This sight base and body are molded from high strength, heat, and impact-resistant proprietary blended polymer. It is mounted to the rail via a locking bar and secured with a cross slotted, knurled thumb screw.
