Steiner MPS-C Ultra-Compact Red Dot Sight

RMSc Footprint - 1.6 MOA Dot - Enclosed Emitter Design The Steiner MPS-C is purpose-built for the demanding environments faced by law enforcement professionals and protection-minded citizens alike. Carrying forward the proven durability of the original MPS, the MPS-C delivers performance in a compact RMSc footprint optimized for slimline pistols and everyday carry. A fully sealed, enclosed emitter shields the optic from debris, moisture, and environmental contaminants, ensuring consistent performance in real-world conditions. The hard-anodized Class III aluminum housing with reinforced sidewalls delivers exceptional impact resistance at just 1.13 oz (32 grams). Featuring a crisp, fast-acquiring 1.6 MOA red dot and exceptionally low-profile design, the MPS-C supports rapid target transitions and intuitive, both-eyes-open shooting—delivering the speed, precision, and confidence serious shooters demand.

Ultra-Compact RMSc Footprint

Specifically engineered for slimline and subcompact pistols, the MPS-C features an RMSc mounting footprint with exceptionally low profile that integrates seamlessly with modern slide-mounted platforms. The compact design minimizes visual obstruction and mechanical interference, proving ideal for concealed carry pistols like the Glock 43X/48, SIG P365, and Springfield Hellcat. The low-profile height maintains compatibility with suppressor-height iron sights for co-witness capability.

Fully Enclosed Emitter Housing

The sealed optical system protects the LED emitter against dust, dirt, moisture, and impact. Unlike open emitter designs that can be compromised by debris or environmental contaminants, the fully enclosed housing ensures the optic maintains a clear dot regardless of conditions. This sealed design proves critical for law enforcement duty use, concealed carry, and competition shooting where reliability cannot be compromised.

1.6 MOA Red Dot

The fine 1.6 MOA dot offers perfect balance between speed and precision. Bright, sharp, and clearly visible under all lighting conditions, the small dot enables lightning-fast target acquisition without obscuring the target at extended ranges. This dot size proves ideal for both rapid close-quarters engagement and precise shot placement at distance.

Intelligent Shake Awake Technology

Integrated motion-sensing technology automatically activates the optic when movement is detected and conserves battery life when at rest. Users can select between always-on operation or 13-hour automatic shutoff for added power management flexibility. The shake awake feature ensures the optic is ready when needed while extending battery life during storage or carry.

Extremely Lightweight - 32 Grams

Weighing just 32 grams (1.13 oz), the MPS-C is up to 40% lighter than comparable red dots. This reduced weight minimizes slide mass, enhances pistol balance, and shortens slide reciprocation time. The lighter reciprocating mass translates directly into faster follow-up shots and improved control during rapid strings of fire.

Class III Hard Anodized Aluminum Housing

The housing is machined from aluminum and treated with Class III hard anodizing for exceptional surface hardness and corrosion resistance. Reinforced sidewalls deliver exceptional impact resistance, protecting the optic from the abuse of daily carry, duty use, and competition shooting. The robust construction withstands drops, impacts, and the battering recoil of compact pistols.

50 MOA Windage and Elevation Adjustment

The MPS-C provides 50 MOA total adjustment range for both windage and elevation with 1 MOA per click. This adjustment range accommodates zeroing across various ammunition types and shooting distances while the 1 MOA clicks enable precise sight-in without excessive adjustment.

Unlimited Eye Relief

The non-magnified optic provides unlimited eye relief, allowing comfortable shooting with any head position or presentation. This feature proves particularly valuable for both-eyes-open shooting technique and rapid target transitions during dynamic shooting.

CR1632 Battery Power

Powered by a readily available CR1632 battery, the MPS-C delivers extended runtime. The shake awake feature and optional auto-shutoff maximize battery life, while the common battery type ensures replacement batteries are easily sourced.

Proven MPS Platform

Built on the same trusted foundation as the original MPS, the MPS-C brings Steiner's renowned durability and optical quality into a format optimized for slimline pistols. The optic delivers rugged performance and intuitive operation now tailored for concealed carry and compact pistol applications. The Steiner MPS-C delivers professional-grade performance in an ultra-compact package—proven reliability meets modern concealed carry requirements.
