Steiner MPS Micro Pistol Sight Red Dot 3.3 MOA Black 8700-MPS

Overview of the Steiner MPS Micro Pistol Sight | 8700-MPS

Steiner has supplied mil-spec optics to armed forces worldwide for decades, and the Micro Pistol Sight (MPS) carries that same engineering to your pistol. Model 8700-MPS is one of the most compact, rugged red dot sights available for optic-ready handguns, built for law enforcement officers, military personnel, and serious armed professionals who need a sight that performs without compromise.

The Problem It Solves

Switching between iron sights and a red dot under stress costs time you cannot recover. The MPS places a crisp 3.3 MOA red dot at your dominant eye the instant you present the weapon, delivering fast target acquisition without any tunnel vision effect.

Why the MPS Stands Out

• All-metal body with reinforced extra sidewalls -- 1,000 G shock-rated
• 13,000-hour battery life at medium brightness, swappable without removing the sight
• Fully sealed and water pressure-tight to 10 m (33 ft.)
• 2.05 oz -- virtually no added weight on your carry pistol

WCUniforms stocks the 8700-MPS in black for professionals who trust their gear every day.

Key Features

• Construction: All-metal housing with reinforced extra sidewalls that fully enclose the laser emitter and produce a best-in-class 1,000 G shock rating; the angular matte black body keeps a low profile on any optic-ready pistol
• Optic Lens: Effective objective lens 20 x 16 mm with hard broadband anti-reflective coating; true 1x magnification supports both-eyes-open shooting and full situational awareness without any field-of-view narrowing
• Reticle: 3.3 MOA red dot for fast, precise target acquisition at distances from 10 to 150 meters; parallax-free at a fixed 25 m
• Brightness Control: 8 manual brightness levels -- 6 day/night modes and 2 night-vision-compatible modes -- adjusted with the rubber-coated + and - buttons on the right side of the housing; press both buttons simultaneously to lock the setting and prevent accidental changes
• Battery: Powered by a standard CR1632 3V lithium battery rated to 13,000 hours at medium brightness; the top-mounted battery compartment unscrews with the included T-handle tool so you can swap the cell without removing the sight from your pistol; a flashing red light signals low battery
• Auto-Off and Programmable Settings: The MPS defaults to a user-selectable 13-hour auto-off; hold both + and - buttons for 10 seconds to disable it (the dot flashes to confirm the change); hold both buttons for 5 seconds to engage button lockout and prevent any unintended mode changes; note that disabling auto-off also disables the highest brightness setting to protect battery life
• Weatherproofing and Care: Water pressure-tight to 10 m (33 ft.); the sealed design handles dust, rain, and snow without issue; the sight remains fully operational after submersion; if the MPS contacts dirty or salt water, rinse it with distilled water and dry with a soft optical cloth
• Adjustment: Elevation turret on top of the housing; windage turret on the right side, both clearly labeled with directional markings; 1 click = 1 MOA (approximately 1 inch at 100 yards); 90 MOA (50 Mil) of total travel in both axes
• Footprint: ACRO platform; mounts to optic-ready pistols using weapon-specific ACRO baseplate adapters; torque fastening screw to a maximum of 2.16 Nm (mounting plate sold separately)
• Temperature Range: Operational from -40°F to +140°F; storage rated from -40°F to +145°F
• Color and Finish: Matte black; hard broadband anti-reflective coating on the lens
• Warranty: Steiner Heritage Lifetime Warranty on mechanical components; 3-year warranty on electronic components for the original purchaser

Specifications

Compatibility

The Steiner MPS uses the ACRO footprint, making it compatible with optic-ready pistols that accept ACRO-pattern baseplate adapters. A weapon-specific ACRO adapter plate is required to mount the MPS and is not included.

Verified Compatible ACRO Adapter Plate Manufacturers (per Steiner)

American Defense Manufacturing, APEX Tactical, Arisaka, Dawson Precision, Forward Controls Designs, Jagerwerks, Overwatch Precision, Primary Machine (RMR-to-ACRO), Reptilia, Strike Industries (RMR-to-ACRO), Unity Tactical.

Common Compatible Pistol Platforms

The MPS works with any optic-ready pistol that accepts an ACRO-footprint mounting plate. Frequently paired platforms include the Glock MOS series, SIG Sauer P320 X-Five and X-Series optics-ready variants, Smith and Wesson M&P M2.0 OR, and other duty and competition handguns with milled slides or ACRO-compatible adapters.

Limitations and Exclusions

The MPS does not drop directly into RMR-cut slides without an adapter. It is not compatible with Picatinny rail mounts or rifle applications. Always confirm your slide cut and use only a matching ACRO adapter plate. Torque the fastening screw to no more than 2.16 Nm; over-torquing risks damaging the mount and shifting zero.

Intended Users

The Steiner MPS 8700-MPS is purpose-built for professionals and enthusiasts who carry or compete with optic-ready pistols and cannot tolerate equipment failure.

Law enforcement officers benefit most from the MPS's combination of rapid target acquisition and durable all-metal construction. The sealed emitter and 1,000 G shock rating mean the sight holds zero through the hard use of daily carry, vehicle exits, and force-on-force training. Officers making the transition from iron sights find the 3.3 MOA dot straightforward to pick up under stress.

Military and armed security personnel carry the MPS knowing the 10-meter water pressure rating and extreme temperature range from -40°F to +140°F cover nearly any operational environment, from humid tropical climates to dry desert heat.

Competitive shooters running USPSA, IDPA, or similar pistol sports choose the MPS for its true 1x view, lightweight profile, and accessible brightness controls. The low-profile housing eliminates any tunnel vision effect and keeps the sight picture wide and natural.

Concealed carry holders and prepared civilians who run optic-ready pistols appreciate the 13,000-hour battery life, which removes the need for constant battery monitoring. The user-selectable auto-off and programmable button lockout let you customize the sight to your carry routine without worrying about accidental changes.
