Meprolight
The Meprolight Mepro MMX3 is a compact 3x magnifier designed to extend the effective range of your red dot or 1x reflex sight without adding bulk to your rifle. Weighing just 9.47 oz with mount, this micro magnifier attaches directly to any MIL-STD-1913 Picatinny rail positioned behind your primary optic, making it an ideal choice for shooters who want the flexibility to magnify targets when needed while staying mobile and fast on close-range engagements.
The MMX3's real-world advantage is its flip-to-side design. When you don't need magnification, a simple pushbutton lets you flip it out of the way without removing it from your rifle—no tools, no fumbling. That quick-access versatility makes it popular among tactical shooters, competition riflers, and hunters working variable distances where you might punch targets at 25 yards and then glass something downrange. The 7.2° angular field of view and wide eye relief of 2.65" support both-eyes-open shooting, keeping situational awareness high when speed matters.
Elevation and windage dials give you precise field-of-view alignment, and the diopter adjustment (±2.0) lets you dial in a clear image for your eye. The 18mm objective and 6mm exit pupil are optimized for the magnification level, while the compact 2.8" length means you're not adding much to your sight line. Build quality is solid—the MMX3 handles storage from -22°F to 76°F and operating temperatures from -4°F to 122°F, with IPX7 submersion rating for wet conditions.
If you're running a quality red dot and want to reach out farther without swapping optics or adding weight, the Mepro MMX3 delivers practical magnification in a lightweight, quick-flip package.

Yes. The MMX3 is designed to magnify red dot and 1x reflex sights. It mounts directly behind your optic on any MIL-STD-1913 Picatinny rail, and the 2.65" eye relief and flip-to-side design keep it compatible with most standard sight setups.
Exactly. The pushbutton-activated flip mechanism lets you move the MMX3 to the side without removing it from the rail. That means quick transitions between magnified and unmagnified shooting without tools or reinstallation.
The magnifier weighs 9.47 oz with mount and is only 2.8" long, making it one of the most compact options available. When flipped to the side, it doesn't interfere with your sight picture or add meaningful length to your rifle.
The product comes with the magnifier and mount ready to attach to MIL-STD-1913 Picatinny rails. We recommend verifying that your specific sight setup has adequate rail space for mounting.
