Description
This ultra-compact solar-charging rifle sight eliminates battery replacement concerns while delivering precision red dot performance for rifles and carbines.
Never worry about dead batteries again. The Holosun SCRS RD 2 combines innovative solar-charging technology with a rechargeable internal battery to provide unlimited runtime when exposed to natural or artificial light. Its compact 20mm tube design weighs just 2.45 ounces while maintaining the durability and precision needed for serious rifle applications, from competitive shooting to hunting and training.
Key Features
- Solar Failsafe Technology: Multi-directional light sensors charge the internal battery while simultaneously powering the optic, ensuring reliable operation with up to 50,000-hour battery life in night vision mode
- Shake Awake Function: Automatically activates with the slightest movement and powers down after 10 minutes of inactivity to conserve energy while keeping the sight instantly ready
- Three Operating Modes: Choose between Auto Mode for automatic brightness adjustment, Manual Mode for precise control across 12 settings (8 daylight and 4 night vision compatible), or Lockout Mode to prevent accidental changes
- Ultra-Compact Construction: CNC-machined from 7075 T6 aluminum with an anodized finish, measuring just 1.7 inches long and weighing 2.45 ounces for minimal added weight to your rifle
Important Compatibility Notes
- Rifle Use Only: This optic is NOT designed for handgun mounting, despite using the 509T footprint—handgun slide reciprocation will damage the optic
- Comes with a lower 1/3 co-witness mount (1.63″ height) for Picatinny rails
- Compatible with 509T footprint mounts, including offset configurations from manufacturers like ADM, Scalarworks, and Reptilia
Why We Carry It
The SCRS RD 2 represents a significant advancement in red dot technology by eliminating external battery dependence. While traditional red dots require battery replacement every 1-2 years, the SCRS maintains power through solar energy collection and an internal rechargeable battery. According to multiple field reviews, the optic can remain stored for extended periods and achieve full charge with approximately 50-60 hours of exposure to direct sunlight or artificial light. This innovation particularly benefits shooters who maintain multiple rifles or those concerned about battery availability during extended use.
Frequently Asked Questions
How does the solar charging system work in low-light conditions?
The SCRS features both solar collection and an internal rechargeable battery. In bright conditions, the solar panel powers the optic while charging the battery. In low-light or indoor environments, the optic runs on stored battery power. The system seamlessly switches between sources, and the 50,000-hour battery life rating ensures extended use even without regular sun exposure.
Can I use this sight for close-quarters shooting on AR-15 pistols or PDWs?
Yes, the SCRS works excellently on AR-15 pistols, personal defense weapons, and short-barreled rifles. The 2 MOA dot provides sufficient precision for close to medium-range engagements. However, do not mount this optic directly to a handgun slide—it’s designed specifically for rifle and long gun applications where the optic remains stationary relative to the barrel.
What mounting options are available beyond the included lower 1/3 mount?
The SCRS uses the 509T footprint, providing compatibility with numerous third-party mounts, including quick-detach options, offset configurations for use alongside magnified optics, and alternative height risers (absolute co-witness, 1.93″, etc.). Popular manufacturers like American Defense Manufacturing, Scalarworks, and Reptilia offer compatible mounting solutions.
