The MEPROLIGHT MEPRO M21 is an innovative, self-illuminated reflex sight, designed to provide unmatched tactical superiority. Originating from the Israeli Defense Force, this red dot sight is a result of advanced Meprolight® tritium technology, employed globally by militaries and law enforcement agencies.
The M21 is powered by fiber optics during the day and Meprolight® tritium at night, offering all-light aiming without the need for batteries. This seamless transition between systems ensures high contrast between the aiming dot and the target area, enabling optimal visibility in all light conditions. Its tritium luminance is warranted for ten years.
The sight boasts a wide 30mm diameter lens, providing a large field of view for rapid target acquisition. Its versatility is further enhanced with five different reticles – MOA or 5.5 MOA dot, Triangle, 4.3 Bullseye, and X – increasing your accuracy and speed under pressure.
Engineered to withstand harsh conditions, it meets rigorous MIL-STD-810 standards, proving its reliability in extreme weather conditions. Compatibility with Night Vision Goggles or scopes, including those with GEN III tubes and magnifying scopes such as the Mepro MX3F/T, adds to its functionality.
With no need for batteries or switches, the MEPRO M21 is always ready, making it a dependable choice for those in demanding tactical scenarios.

Customer Questions & Answers
Will this work on 45 colt long rifle?
- If your rifle has a flattop upper receiver with an M1913 picatinny rail. If not, then you'll have to mount the optic over the hand guard with some different hardware.
Would this handle recoil from a 12g ok?
- It probably would but it is really not designed for use with a shotgun.
I live in a dark area w/ few lights. With the Night Reflex part of the sight; how well do you see in complete darkness, full moon & suburbs w/ lights?
- The dot will show in almost total darkness but unfortunately your target will not. But the m21 is awesome when paired with a night vision scope like a PVS-14. The dot is bright but not too bright and needs no special setting for night vision like some other red dots.
How long does the tritium last and is it replaceable? If so, how much does that cost?
Mepro claims 12 years but in my experience you can expect 9 to 10 years of life from the tritium vial. Yes, you can send it in to Mepro for replacement. I can't tell you how much it costs or what turnaround time is though.
If you buy this optic get the 4.3 MOA dot. Don't get any of the other reticles. They are too big.
