Primary Arms SLx MD-25 Rotary Knob 25mm Microdot with 2 MOA Red Dot Reticle
- IV8888 Reviews Primary Arms SLx MD-25
Available for Pre Order/Back Order ETA: Aug
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.

This is better than an MRO
by Chris Peterson
I have this on a Foxtrot Mike 16” 9mm upper and absolutely love it. Did a side by side with this an MRO, and the PA SLx blows the MRO away.
Nice little optic

<br>Target used at 200 yds was an 18" body silhouette. All hits were center mass. Great little optic. And a shout out to all at PA for the outstanding work and customer service during these Covid times.
Awesome red dot, best bang for the bucks

Pre-ordered this in May and it came in early June. I put it on my X95 right away and this thing rocks. Later I rattle can painted it to multicam and it looks even better. The 25mm objective lens make a big different when comparing to my Holosun red dots. Of course it is a bit heavier but who cares. I noticed that there's a small amount of blue-green tint to it, but it doesn't bother me. Over all great buy for the money, can't go wrong.
Great red dot.
Great red dot. I really enjoy the wider field of view and the mount is awesome. I'll definitely be getting another one for my other AR.
As someone who has used primary arms optics as my go to sights I am once again impressed. I wanted a larger window, great reliability and long battery life. This one hits all the marks. The mount seems heavy duty and gives you multiple options.
Equal to Trijicon MRO for a fraction of the cost..

Honest review... True 5 STAR product. Wide field of view. Held Zero after 500 rounds. Compared to Sig Romeo 5 and Trijicon MRO. Much better than Romeo 5 and equal to Trijicon MRO. For the money. This is the best option..
Packed with features and excellent flexibility out of the box!
The larger objective does help the constricted feeling you generally get when looking through a micro dot. With two eyes open, the larger dial and knobs disappear. The whole sight feels extremely high quality and I think the mount is a huge improvement over the typical cheap feeling mount found on cheaper micro dots. The fact that it includes a low mount and high mount with multiple spacers makes this sight capable of multiple setups out of the box.
<br>While there are no "off" points in between settings, the battery life makes this a "set it and forget it" for a long time, making it unnecessary to turn it off. The brightness dial is stiff, keeping it from accidentally turning (an issue I had on my old aimpoint PRO) when stored in a case / bag. But you can still easily adjust it. The adjustments when sighting in are very tactile with clear and pronounced "clicks".
<br>Primary Arms really delivered with this sight and it's a steal at this price point.
Just got mine in the mail today and installed on a PWS MK111 Mod 2 SBR. Right out of the box I was impressed with build quality, feels solid. Optic comes with multiple bases/risers to let you achieve co-witness preferences. Dot is crisp and bright. Primary Arms included a t-handle torx wrench instead of a flimsy angled wrench so you can really get some purchase when tightening the mount down. Will take it out soon to shoot after my scalarworks peak iron sights come in. Shipping was fast as always, Primary Arms simply can't be beat.
