Solar Failsafe™
Solar Failsafe Technology is one of many innovations featured on solar-equipped Holosun optics. With Solar Failsafe, if your battery fails you always have a backup power source when natural or artificial light is available. Solar Failsafe is activated while in Auto Mode where reticle intensity is automatically adjusted based on the amount of light the solar cell receives. In brighter conditions you have a brighter reticle and in lower-light conditions the reticle will step down in intensity to match any lighting conditions. On models equipped with a super capacitor, it is possible to run the optic, indefinitely, in daytime and night conditions, by maintaining a charge through the Solar Failsafe System all without a battery.

Unrivaled Protection: Holosun EPS Red Dot EPS-RD-MRS Enclosed Pistol Sight
Step into the future of handgun optics with the Holosun EPS Red Dot EPS-RD-MRS, a revolutionary enclosed pistol sight designed for shooters who demand a completely protected emitter for absolute reliability. As a next-generation optic, the EPS-RD-MRS combines the proven technology of Holosun’s Multiple Reticle System (MRS) with a sealed, full-sized housing, ensuring dust, moisture, and debris never interfere with your red dot. This is the ultimate enclosed red dot sight for duty, competition, and serious everyday carry (EDC).
Next-Level Features of the EPS-RD-MRS
The Holosun EPS Red Dot integrates a suite of advanced features, setting a new standard for pistol optics:
-
Multi-Reticle System (MRS): The heart of this optic is its versatility. Utilize the fast 32 MOA circle-dot for quick acquisition, switch to the fine 2 MOA dot for precision aiming, or use the 32 MOA circle alone. The vibrant Red Super LED provides 8 daylight and 4 night vision compatible brightness settings.
-
Solar Failsafe™: This key technology uses a solar panel to automatically adjust the reticle brightness to ambient light conditions and serves as a vital backup power source, maintaining functionality even if the CR1620 battery runs low.
-
Shake Awake™: Holosun’s smart motion-sensing system extends the battery life up to an incredible 50,000 hours by deactivating the LED during periods of rest and instantly re-activating it upon movement.
-
K Footprint with RMR Adapter: The Holosun EPS-RD-MRS utilizes the common Holosun K-series footprint for a direct, low-profile mount on specific pistols (like the Glock 43X/48 MOS and SIG P365 XL). Crucially, it includes an RMR-to-K adapter plate in the box, making it easily compatible with the widely used RMR footprint common on full-size pistols.
-
IP68 Certified: With an IP68 rating, this sight is completely dust-tight and fully submersible, confirming its readiness for hard use in any environment.

Arax systems is the best. I have bought about 6 or 7 EPS redots from here and zero issues even 2 years out so far. Shipping is quick, the pricing is unbeatable for holosun optics at least. Never had a issue. Found this site by pure chance and glad I did.
