Primary Arms SLx MD-25 Microdot Red Dot

The Primary Arms SLx MD-25 microdot is a hard to beat package when you want speed and a lightweight optic. The venerable 30 mm red dot is a great option for shooters who prefer to have speed AND a wide field of view through their optic. The SLx MD-25 is here to offer the perfect balance between the two with a compact design that weighs barely 2 ounces more than a standard microdot, yet offers the same field of view as a 30 mm red dot! Add in super bright, daytime illumination, a 50,000-hour battery life, and our next generation ruggedized micro mount and you’ll see how we’re pushing the envelope for fast, lightweight optics!

The SLx optics are the heart of our lineup. The trusted optics that have built our reputation through the years. Although many SLx optics will be familiar to Primary Arms fans, we are always pushing forward with new generations and adding even more options in response to the demands of our loyal customers.
