Product Description The Primary Arms SLx MD-25 Rotary Knob 1x25mm Microdot Reflex Sight is a compact, lightweight, and battle-ready red dot optic engineered for fast target acquisition and all-day reliability. Built on the trusted SLx platform, this microdot features an exclusive ACSS-CQB red dot reticle, a hardcoat anodized aluminum housing, and an enclosed emitter design that delivers durability in demanding environments. The MD-25 now includes AutoLive technology, a motion-activated on/off system that powers the dot the instant you pick up your firearm and conserves battery when the rifle sits still. Despite its compact 25mm objective lens, the MD-25 offers a field of view that rivals larger 30mm red dots, making it an exceptional value for both duty and recreational use. The RMS footprint provides broad compatibility with popular pistol slide cuts and mounting solutions. Product Highlights AutoLive Motion Activation: Automatically powers the red dot on when the firearm is picked up and shuts off to conserve battery when motionless, ensuring the dot is ready precisely when you need it. Exclusive ACSS-CQB Reticle: Purpose-built for close-quarters engagements, the ACSS-CQB red dot reticle enables faster, more intuitive target acquisition at any shooting distance. Compact 25mm Enclosed Emitter: The enclosed red dot emitter in a 25mm objective lens package delivers a wide field of view comparable to larger 30mm optics while keeping the overall footprint small and lightweight. Aircraft-Grade Hardcoat Anodized Aluminum: The rugged aluminum construction with a hardcoat anodized finish ensures long-lasting resistance to wear, corrosion, and harsh field conditions. RMS Footprint Compatibility: The RMS (Rear Miniature Sight) footprint ensures broad compatibility with a wide variety of pistol slides and mounting platforms right out of the box.
