The MRS-1 is Colt Optics’ micro red dot sight – a 1x optic built around a crisp 3 MOA dot and engineered to do one job flawlessly: put an aiming point on target the instant you need it. It mounts on the industry-standard Acro footprint and weighs just 2 ounces, so it rides as easily on a pistol as it does on a carbine or a PCC.

Power is something you’ll stop thinking about. A single CR2032 drives the dot for up to 75,000 hours on the middle setting, and built-in motion activation wakes the sight the moment you pick up the firearm and stands it down when you set it aside. Twelve brightness settings – eight for daylight, four for night vision – keep the dot dialed in from bright sun to no-light work behind NODs.

Simple, repeatable, and built to take a beating: 1 MOA windage and elevation clicks, 35 MOA of travel in each axis, and a sealed body designed to hold zero and shrug off impact. No clutter, no second-guessing – just a dependable dot when it counts.
