Meprolight M21 1x 30mm 4.3 MOA Red Dot Reflex Sight
The Meprolight M21 Red Dot Sight, originally developed for and still in active service with the Israel Defense Force (IDF), represents a robust application of Meprolight’s tritium illumination technology. This dual-illuminated 1x reflex sight is engineered for sustained operational reliability and rapid target engagement across diverse combat and tactical environments. Its design priorities focus on consistent performance without reliance on external power sources.
Key Features
Dual Illumination Technology
The M21 employs a sophisticated dual-illumination system, utilizing both fiber optic collectors for ambient light and a self-contained tritium light source. This engineering ensures consistent reticle visibility without batteries across all lighting conditions, from bright daylight to total darkness. The 4.3 MOA red dot reticle provides a clear and immediate aiming point, optimizing target engagement speed.
Optical Clarity and Field of View
Featuring a generous 30mm objective lens, the M21 delivers an expansive field of view, which is critical for maintaining situational awareness and accelerating target acquisition in dynamic engagements. The 1x magnification provides a true-to-life sight picture, eliminating distortion or parallax common in lesser optics.
NVG and Magnifier Compatibility
Engineered for operational versatility, the MEPRO M21 maintains full compatibility with Night Vision Goggles, including those equipped with GEN III tubes, and various magnifying scopes such as the Mepro MX3F/T. Its optimized design facilitates seamless integration of a magnifier in close proximity to the optic, ensuring no decrease in the field-of-view and without compromising convenient switch operation.
Operational Reliability
Validated through rigorous military deployment and active service with the IDF and global law enforcement agencies, the M21’s design prioritizes durability and consistent performance under extreme conditions. Its self-illuminated nature removes dependence on external power sources, mitigating potential points of failure inherent in battery-dependent systems and ensuring readiness in critical situations.
