Description The Sightmark Mini shot M-Spec Solar Enclosed M4 brings serious innovation to compact red dot optics. Built on a rugged ACRO® footprint and crafted from durable 6061-T6 aluminum, this enclosed reflex sight is ready for rifles, shotguns, and handguns alike. With a generous window size, shooters get faster target acquisition and better situational awareness compared to other Mini shot models. The Mini shot M-Spec Solar Enclosed M4 offers a versatile reticle system—users can cycle between a precise 3 MOA dot, a fast-acquisition 32 MOA circle, or a circle-dot combination. Its advanced shake-awake technology powers down the sight after 5 minutes of inactivity, instantly reactivating with movement, while the solar panel extends battery life and ensures reliability in the field. Running on a single side-mounted CR2032, this optic delivers up to 105,612 hours of continuous use. Built for harsh environments, the Mini shot M-Spec Solar Enclosed M4 is IPX7 waterproof, fog proof, and drop tested to 5 feet. It features 12 brightness settings, including three night-vision compatible modes, making it mission-ready day or night. Whether you’re a hunter, competitive shooter, or professional operator, this optic combines endurance, adaptability, and cutting-edge tech in a compact package.
