The Mepro M21 Reflex Sight is a cutting edge tactical reflex sight from Israel. Designed to be a sight capable of operating in day or night, using no batteries, the M21 has quickly established itself as the best option for elite forces around the world. WIth the use of tritium gas, the reticle of the M21 will appear bright and clear in any environment and remain so without the need to use batteries or external power sources.
Meprolight designed the M21 through close consultation with the Israeli Defense Force special operations teams. This all-light reflex sight is illuminated by a fiber optic collector system during the day and uses the tritium gas at night. There are no switches or changes necessary to move from day to night operation, everything operation is self contained and selected by the M21. The Mepro M21 will allow shooters to acquire targets accurately at any range, in any situation, with both eyes open.
