New Pistol Optic Addresses Market Demand for Universal Mounting Solutions
Primary Arms Optics has expanded its mini reflex sight lineup with the introduction of the SLx RS-10R, a compact pistol red dot engineered around the industry-standard RMR footprint. This strategic design choice ensures broad compatibility across numerous optics-ready slide configurations and aftermarket mounting systems, addressing a key market requirement for versatile optic solutions.

SHOT Show 2025 Debut and Market Availability
Following its official debut at SHOT Show 2025, the RS-10R is now commercially available through Primary Arms' direct sales channels and their network of authorized dealers at a competitive price point of $209.99, with an MSRP of $234.99.
Advanced Construction and Materials Engineering
Premium Aluminum Architecture
The RS-10R utilizes aerospace-grade 7075 aluminum construction, providing exceptional strength-to-weight ratios essential for demanding applications. This material choice ensures the optic can withstand the repetitive stress cycles associated with both concealed carry scenarios and professional duty use.
Optimized Optical Performance
At the heart of the RS-10R's performance lies its precision-engineered 23×19mm multi-coated lens system. This optical configuration delivers clear target acquisition while maintaining the compact profile necessary for concealed carry applications. The 3 MOA dot size provides an optimal balance between precision shooting capabilities and rapid target engagement.

Power Management and Battery Technology
Extended Runtime Capabilities
The RS-10R incorporates Primary Arms' AutoLive® motion-sensing technology, delivering an impressive battery life of up to 40,000 hours. This advanced power management system automatically adjusts operational states based on detected movement, maximizing efficiency while ensuring the optic remains ready when needed.
User-Friendly Battery Access
The sight features a convenient side-loading CR1632 battery compartment, enabling quick battery changes without removing the optic from the firearm. This practical design consideration reduces downtime and maintains zero retention during maintenance procedures.
Performance Specifications and Features
Compact Profile and Weight Distribution
Weighing just 1.1 ounces, the RS-10R maintains an ultra-lightweight profile that minimizes impact on weapon balance and handling characteristics. This careful attention to weight distribution makes it particularly suitable for both everyday carry and extended duty applications.

Daylight Visible Illumination System
The optic incorporates "Daylight Visible" illumination technology, ensuring reliable dot visibility across varying ambient light conditions, from low-light environments to bright daylight scenarios. This consistent performance eliminates the need for brightness adjustments in rapidly changing lighting conditions.
Design Philosophy and Market Response
Addressing Customer Feedback
According to Stephen Morgan, Director of Product Marketing at Primary Arms Optics, the RS-10R represents a direct response to user requirements identified through market analysis of their original SLx RS-10 model.
"When the original SLx RS-10 released, we received a lot of feedback about its footprint," Morgan explained. "By fitting the RMR mounting pattern, we're giving users more flexibility without compromising on durability or value."
Universal Compatibility Advantage
The adoption of the RMR footprint standard significantly expands the RS-10R's compatibility across multiple firearm platforms and mounting solutions, providing users with greater flexibility in their optic selection without sacrificing performance or reliability standards.
Target Applications and User Base
Professional and Enthusiast Appeal
The RS-10R's feature set positions it as a versatile solution suitable for both professional end-users and civilian enthusiasts. The combination of robust construction, intuitive controls, and extended battery performance creates a practical option that meets diverse operational requirements.
Concealed Carry and Duty Optimization
The optic's compact dimensions and lightweight construction make it particularly well-suited for concealed carry applications, while its durable materials and reliable performance characteristics ensure it can handle the demands of professional duty use.
