If you haven't' heard for Meprolight you definitely need to check them out. An Israeli company making a wide variety of both iron night sights and optics from reflex sights and magnifiers to traditional optics with ranging capabilities. Their products are heavily in use with the IDF (Israeli Defense Force) and with many military, police and civilian shooters around the globe.
The Meprolight Tru-dot night sights are the best on the market, providing the brightest dot system available, as well as certain colour combinations to suit your needs.
The M21 reflex sight system uses no batteries, just fiber optic and tritium to provide you with an aiming system no longer dependent on how good the batteries are, as well as offering different options in reticles
to suit the needs of any shooter.
The MOR system takes the M21 and adds an additional battery illumination system and either a visible laser or both a visible and NV laser to the package.
