The Classic Series™ proves that entry-level optics don’t have to be poor-quality optics. Unlike some other brands, we don’t use the word “value” as a euphemism for “junk”. Classic Series scopes are perfect for the budget-conscious and the new shooter. We take the time to 100% inspect every product in our facility here in Houston to ensure you are receiving the best quality product as our other three tiers. These scopes are backed by the same excellent customer service and support as all other Primary Arms products.

This Primary Arms Microdot sight is our second-generation model that comes in at an affordable price while retaining excellent quality and durability. We have included a MIL-STD-1913 Picatinny rail mount with this red dot sight, so you can attach it to your rifle right out of the box in a matter of seconds and head to the range to get it sighted in. Alternatively, the mount is removable and features mounting options for other standard microdot riser mounts, so you can customize the height and co-witness with your iron sights. Adjusting the zero of the dot is made easy with the 1/2 MOA audible click adjustments that are protected by aluminum caps. Also included with this optic is a bikini lens cover to protect the glass when not in use. If you are in the market for a red dot sight for hunting, target shooting, or competition, you can’t go wrong with the Primary Arms Microdot.

The 2 MOA red dot is extremely crisp and allows you to take quickly aimed shots at short range while still giving you the ability to make effective shots at medium ranges. The glass that the red dot is projected on is fully multi-coated to reduce reflection and provide a clear sight picture. The glass and electronic internals are covered by a durable, black hard coat anodized, 6061 aluminum housing with O-rings providing protection from water and fog.

Great micro red dot for the price


Used on my IO Inc AKM247 (AK47 clone). When used with the Midwest handguard, it co-witnesses the iron sights PERFECTLY!EXCELLENT value!

Excellent Deal


Very happy with this purchase and the quality of the micro dot sight I ordered for the money. Will most defiantly order future products again. The shipping speed is second to none!

As good as they say


Very happy with this scope, which is worth the price. However, I think I'm going to buy the Advanced one next, with the QD. Just can't get it out of my mind :)

Excellent Product


Well made and durable; this Red Dot has worked perfectly.

Perfect for defense rifles


When I first got it in mail, the mounting screws were in waay too solid (that's a good thing), sadly I stripped out some screws and couldn't mount it to riser. Primary arms must have 2 day shipped me a new one. I got it fast and in good condition. If you are a civilian, why do you need an aimpoint that costs half or a third of your rifle? I cant justify that. Primary arms is my first stop for optics. Keep em coming PA.



Will buy more of this type product

PS90 perfect fit


Works just right on my PS 90

Awesome budget red dot!


You can't beat this optic for the price. Period! Solid as can be, great clarity, awesome battery life, what's not to love?? Buy one!

customer service


Your guys on the phone customer service were vary genuine and helpful. Whatever question I had they awnsered quickly and without hesitation. One of the best experiance I've had ordering product.

awesome so far!


zeroed today in record time, seems like a quality piece. Small sharp dot with solid "click" to the MOA adjustment. I am glad, tho, that I ordered both the lower 1/3 and absolute co-witness riser mounts because my only "complaint" was that with the 1/3 riser, the emitter was visible while sighting down the iron sights, making for a very cluttered sight picture for my preference. Just something to be aware of. after swapping to the absolute co-witness mount, i couldn't be happier. Well worth the investment, and much more precise than the iron sights. Would definitely recommend to friends and family.
