The Classic Series™ proves that entry-level optics don’t have to be poor-quality optics. Unlike some other brands, Primary Arms doesn't use the word “value” as a euphemism for “junk”. Classic Series scopes are perfect for the budget-conscious and the new shooter. Every product is inspected in the their facility in Houston to ensure you are receiving the best quality product as the other three tiers. These optics are backed by the same excellent customer service and support as all other Primary Arms products.

Bridging the gap between the Classic Series micro dots and the more premium SLx MD-25, the new Classic Series RD-25 brings the field-proven advantage of a 25mm aperture to an affordable optics line. With its wider field of view, the RD-25 offers greater visibility and situational awareness when looking through your optic. The RD-25 has also undergone extensive recoil and field testing to prove that it is just as durable as more expensive optics, so you can be confident that this microdot will last. Not only is the aluminum housing extremely durable but it features fully multi-coated lenses that are anti-reflective and fog resistant and has been rated at IP67 for water resistance. The high-power LED emitter provides plenty of visibility even on the brightest days and the top mounted buttons make it easy to cycle through all 10 brightness levels. Right out of the box, the RD-25 red dot sight comes with a rugged and lightweight QD mount with an adjustable tension lever, so you can don't have to worry about shopping for a new mount. However, it still uses the industry standard mounting footprint, so you can pair it with the Primary Arms Micro Dot Offset mount for use with either the 3x or 5x MicroPrisms™.

Hands down best bang for the buck


This optic is perfect. I like having dedicated optics that stay on its own rifle. Obviously that gets too pricey for the average man. Wanted something that wasn’t going to drain my bank account, but i still can’t stand cheap feeling optics. I’m so glad I chose this. I’m almost 40, I feel my eyes aren’t as they were when I was 18. The larger FOV makes a big difference, and the dot is clear and it can go really bright. Those were important factors for me. Mount is a nice touch as well, great simple design, locked on rock solid once you got the QD lever adjusted correct. I won’t hesitate to buy again.

Quick and simple to zero the mount works well for transitioning from iron sights to optic on my AK 101. Easy to operate
