The Steiner MPS-C 1.6 MOA Red Reticle Reflex Sight 8700000039 is the enclosed emitter reflex sight from Steiner built for duty, defensive, and competition shooters who need a compact, reliable red dot that protects the emitter from the environmental conditions that open emitter designs are vulnerable to — moisture, debris, and physical impact that can compromise optical function at the worst possible moment. The MPS-C delivers Steiner's optical quality and construction standards in a compact housing that works equally well on pistol slides, carbines, and professional duty platforms. The Steiner MPS C enclosed-emitter design keeps the LED and optical system protected inside a sealed, rugged aluminum housing — no exposed emitter to collect debris or moisture, or to sustain impact damage during hard use. For duty and defensive shooters who carry in varied weather conditions and cannot accept optical system failures due to environmental exposure, the enclosed design removes that failure mode entirely from operational considerations. The MPS-C 1.6 MOA illuminated red dot provides a precise aiming reference that leaves maximum target visible around the dot at any engagement distance — a smaller, more precise dot than many competing compact reflex sights offer, making it the natural choice for competition shooters who engage smaller targets at distance and duty shooters who need the most precise aiming point their compact optic can deliver. The 8700000039 multiple brightness settings include night vision-compatible levels that cover every lighting environment, from bright daylight through complete darkness, with NV devices — the full lighting spectrum that serious duty and defensive shooters operate across. Features: Enclosed emitter housing — protected from debris, moisture, and impact 1.6 MOA red dot for maximum precision and target visibility Night vision compatible brightness settings for full lighting spectrum coverage Motion-activated illumination for extended battery life Rugged aluminum construction for hard duty and field use Steiner MPS-C 1.6 MOA Red Reticle Reflex Sight 8700000039
