Fast, Reliable, Battery-Free Reflex Optic
The Meprolight M21 Reflex Sight is a rugged, combat-proven optic designed for shooters who want fast target acquisition, dependable operation, and a simple point-of-aim system. Featuring a 1X magnification and 12 MOA reticle, the M21 provides an intuitive sight picture that is especially well suited for close- to medium-range applications.
One of the M21's standout features is its battery-free illumination system. The sight uses fiber-optic technology to collect available ambient light and illuminate the reticle, while a tritium element provides illumination in low-light conditions. This means the optic is ready when you need it without relying on conventional batteries.
The 12 MOA reticle provides a highly visible aiming point that allows shooters to acquire the target quickly, making the M21 an excellent choice for defensive firearms, carbines, and other platforms where speed and reliability are priorities.
