Meprolight M21 Reflex Sight - Bullseye Reticle
The Meprolight M21 is a self-powered day/night reflex sight. The M21 features a large 30mm diameter lens that provides quick and instinctive accurate shooting. Designed in cooperation with the Israeli Special Forces, the M21 is battle tested and easy to use day or night. During the day, the M21 is illuminated through its fiber optic collecting system and by a self-powered tritium light source at night. The transition is instantaneous due to no batteries or switches, and the durable optic housing means the M21 can be operated under all temperature and weather conditions. Comes with a quick detach mount, dustcover and bullseye reticle.
