The DSMR is designed to quickly attach/detach from standard size handgun/rifle with Picatinny/Weaver rails. Tubeless design with 33mm reflex lens aperture provides a wide field of view, suitable for rapid-firing or shooting of moving targets besides normal shooting. Multi-reticle 4 patterns or Variable Dot are installed. Parallax corrected and unlimited eye-relief. Allen head screw type windage and elevation click adjustments, with locking screw. Built-in mount (integrated rail) for standard bases, no need to rezero when mounting the dismounted sight. Very light weight, waterproof and shockproof. Low power consumption for long battery life.
