The Meprolight Mepro 21 is a dual illuminated battery free red dot sight. It was first issued to IDF SF in late 1990’s. In 2002 Meprolight won the IDF contract for a new standard issue red dot sight, and it was issued to both SF and regular units replacing the Elbit Falcon and the Trijicon Reflex.


In late 2015 the Meprolight M5 won the IDF bid for its future standard issue red dot sight and has been replacing the Mepro 21 since. 


  • Gen I - single fiber optic located on top of the objective lens.

Key features:

  • Large 30mm aperture, providing a wider field-of-view than the Trijicon Reflex 24mm aperture.

  • Integrated light collecting fiber optics located around the top and front portions of the sight, collecting more ambient light and project a stronger aiming dot the Trijicon Reflex single fiber optic, which is located just in front of the lens.
