Meprolight USA M21 1x 30mm 5.5 MOA Dot Reflex Sight - Black

The Meprolight M21 is a self-illuminated reflex sight built for instant all-light aiming without the need for batteries. Developed for the Israel Defense Force and trusted by militaries and law enforcement agencies worldwide, the M21 uses a combination of tritium and fiber optic illumination to deliver a bright aiming point in any lighting condition — always on, no switches required, and completely maintenance free.

Featuring a large 30mm objective lens and an unobstructed 1x sight picture with unlimited eye relief and an unlimited field of view, the M21 allows rapid target acquisition with both eyes open. The 5.5 MOA dot reticle is well suited for close- to medium-range engagements and remains clearly visible in daylight, low light, and total darkness, making the optic compatible for use with Night Vision Goggles or magnified scopes.

Built to MIL-SPEC standards and finished in durable matte Black, the M21 measures 4.48" long, weighs 13.12 oz, and mounts via a quick-release Picatinny interface. Adjustable windage and elevation allow the user to zero the optic to the host platform, while weather-resistant construction keeps the sight operational in adverse conditions. Made in the USA by Meprolight, the M21 is a rugged, battery-free combat optic ready for duty use.
