The LaserMax Micro Red Dot Sight (brand part no. LM-MRDS) is an ultracompact 4 MOA red dot built for RMSc-footprint, optics-ready carry pistols. Machined from aircraft-grade aluminum, the housing is sized to sit flush on a slide instead of adding bulk to an everyday-carry gun. An external light sensor reads ambient conditions and automatically adjusts dot brightness, while a shake-to-awake feature saves battery when the sight is holstered. A single CR2032 battery, included along with Picatinny mounting hardware, powers roughly 10,000 hours of runtime across 8 daytime and 2 nighttime brightness settings.

Key Specifications

• Reticle: 4 MOA red dot, sized for quick target acquisition on a compact-carry pistol.
• Adjustment: 1 MOA per click, for windage and elevation, fine enough to zero precisely without overshooting.
• Magnification: 1x, a true parallel-vision red dot with no magnification distortion for both-eyes-open shooting.
• Overall length: 1.60 inches, an ultracompact footprint built to sit flush on a slide without adding bulk.
• Optic coating: multi-coated lens, improves light transmission and reduces glare in mixed lighting.
• Eye relief: unlimited, so the sight picture stays consistent regardless of head position behind the slide.
• Housing: aircraft-grade aluminum, built to handle slide-cycle recoil on a daily-carry pistol.
• Light sensor: external ambient sensor, automatically adjusts dot brightness so you are not stuck resetting it by hand.
• Battery: CR2032, included, with a roughly 10,000-hour runtime and 8 daytime / 2 nighttime brightness settings.
• Footprint: RMSc mounting pattern, drops directly onto optics-ready pistol slides cut for RMSc-pattern red dots.
