The Meprolight Mepro M21 reflex sight with a triangle reticle (brand part no. 626410) is a self-illuminated red dot style sight that never needs a battery. It uses fiber optic illumination by day and Meprolight tritium by night, so it is always on and always ready. The sight was originally developed for the Israel Defense Force and remains in service with militaries and law enforcement agencies worldwide. A 30mm lens gives a wide field of view with both eyes open, and the sight is parallax free. This version ships with a Picatinny adapter and dust cover.
