Helpful Positive Review Death to batteries! by Legacy Reviewer, Verified Owner, May 24, 2012
I just got this, and I already like it better than my Eotech. No batteries, built in qd mounts, built like a tank. When there is sunlight, the reticle is bright, very bright. It is dimmer indoors during the day, but still pleasant and clear. The ...

Helpful Positive Review M21 optic review by Mac, November 10, 2023
Built like a tank. Haven’t sighted it in yet. Only draw back is reticle is quite dim in low light, was hoping it would be similar to Trijicons in low light. For the price, it’s a fantastic sight. If you are looking for a fiber optic sight that’s grea...

Helpful Positive Review Mepro light m21 by Austhee, November 21, 2023
Optic is well built and glass is crystal clear. Reticle is bright enough to visibly see under day time or night time conditions but I have not tested it while using a weapon light at night.

Product Info for Meprolight M21 Self-Powered Day & Night Reflex Sight w/ Dust Covers

The MeproLight M21 Self Powered Day/Night 1 x30mm Illuminated Reflex Sight provides constant, all-light aiming capability, without the need of a battery supply. Reticle illumination on these Red Dot Sights by Meprolight is achieved by a protected fiber optic light collector system during the day, and by a miniature self-powered tritium light source at night. Night vision compatible, the Meprolight Self Powered Reflex M21 Tactical Sight features a large 30mm diameter lens that provides rapid target acquisition with both eyes open. This Meprolight red dot sight has a quick-release Picatinny mount that perfectly retains zero. Designed through close collaboration with Israeli Special Forces, the Meprolight Self-Powered Red Dot Reflex Weapon Sight is the first reflex sight in the world designed for close quarter combat.image
