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.

The humble microdot is a hard-to-beat package when you want speed  without adding a lot of weight to your firearm. The venerable 30mm 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 30mm 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 25mm Red Dot been equipped with our next generation ruggedized mounting system. We’ve upgraded everything about the mount from materials and finish to the design to create a mount that will not just clamp securely to your rail, but stand up the rigors of real-world use. Integrated recoil lugs help lock your mount in place against the heaviest recoil while large diameter crossbolts give you significantly improved clamping power and will hold up to significant torque. The included riser is the perfect height for AR-15s and AR-10s, but can be easily removed to for installation on AKs, shotguns, and more.
The SLx 25mm red dot includes the low base, a standard riser, and two different height spacers, as well as appropriate mounting hardware. With just the low base, a central height of 0.96” can be achieved. Add the standard riser for 1.41”. With the riser and thin spacer, your central height will be 1.54”. Using the thick spacer will place the optic at 1.64” height. With these options you can easily configure your optic to perfectly match your firearm and shooting style.

Is the viewing window bigger than a Bushnell TRS-26 or a trijicon MRO?
