The Meprolight Mepro M21 reflex sight with a 4.3 MOA bullseye reticle (brand part no. 626110) is a self-illuminated sight that never needs a battery. Fiber optic illumination works by day and Meprolight tritium by night, so the sight is always on and always ready. Meprolight originally developed it for the Israel Defense Force, and it remains in active duty with militaries and law enforcement agencies worldwide. A 30mm lens gives a wide field of view and the sight is parallax free. It is a rugged option for carbines, duty rifles and defensive firearms.
