Mepro USA MPO Pro-S 1x30 Red Dot Sight with MOA Bullseye Reticle and RMSc Mount

The Mepro USA MPO Pro-S 1x30 red dot sight brings proven military-grade durability to shooters who demand an optic that won't fail when it counts. Built on Meprolight's legacy of rugged enclosed optical systems, the Pro-S pairs a compact, impact-resistant design with a clean 3 MOA dot and 33 MOA bullseye reticle—a combination that works equally well for close-quarters shooting, defensive carry, or mid-range precision. Whether you're running a rifle, pistol, or shotgun, this sight adapts to your environment with automatic brightness adjustment, manual backup, and 10 daylight plus 2 night-vision compatible settings.

The enclosed design keeps dust, debris, and weather out of your optical path. At just 1.4 ounces, the Pro-S adds minimal weight to your setup while delivering the field of view and targeting clarity you expect from a quality 1x optic. The RMSc footprint mount means compatibility with modern pistol optics cuts and lets you swap the sight between platforms if needed. Single-MOA windage and elevation adjustments give you the precision dialing you need, and the ±30 MOA travel provides enough room for point-of-impact shifts across distance or hold-over shooting.

Battery life stretches beyond 20,000 hours on a single CR1632 cell, so you're not swapping power regularly. IP67 waterproofing and fog-proof construction keep the sight running in rain, humidity, and temperature swings. If you want a no-nonsense optic built to take hits and keep delivering accurate sight pictures, the Mepro Pro-S earns its reputation.

Frequently Asked Questions

Will the Mepro Pro-S mount on my pistol or rifle?

The Pro-S uses the RMSc footprint, which fits modern optics-cut slide platforms and adapter mounts designed for that standard. If your firearm has an RMSc-compatible cut or you use an RMSc adapter block, yes—this sight will work. Check your platform's specifications to confirm compatibility.

Does it work with night-vision devices?

Yes. The Pro-S includes 2 night-vision compatible brightness settings in addition to 10 daylight-level modes, making it functional with NV equipment when needed.

How long does the battery last?

The CR1632 cell will run the sight for 20,000+ hours on a single charge. That's roughly 2+ years of continuous operation, so battery changes are infrequent under normal use.

What's the reticle design, and what size is the dot?

The Pro-S features a 3 MOA red dot centered in a 33 MOA bullseye ring. This 3-segment reticle design gives you a fine aiming point for precision while the outer ring helps with rapid target location and speed shooting.
