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.

Very Happy


I was very satisfied with the performance of the PRimary Arms Micro Dot. Adjustments were consistent and I was able to get it zeroed in just as I wanted. Shipping was first rate and with their close proximity I had my package in less than two days. I plan to use them a lot more in the future.

I love this thing!


I went through probably 5 cheap sights (under $100) before finding this one. In my determination to find a cheap, reliable sight I probably spent more than I would have just buying an Aimpoint, but this sight came recommended by multiple users of a forum I asked around on so I scooped it up. Couldn't be happier! Probably have 1,200+ rounds down range with it and it's held zero like a boss. The dot is nice and bright and defined and it's easy to look through. If you want Aimpoint quality for less than $100, buy this sight!

Micro Dot


I went to the store and ended up getting a side mount for my Saiga rifle plus buying the red dot. It is a low mount and now I can co witness my iron sights as well. The people there at the store were very helpful in showing me what I needed and how to do it. The red dot works very well on my AK / Saiga. would definitely buy more stuff from these people.

Great product...excellent service


I'd been waiting for these to come back in stock. Got an email at 12:15 pm on 10-29-14 from PA stating they were back...placed my order at 1:03 my product shipped notification at 2:01 pm...delivered to my door 1,150 miles away using standard shipping at noon on 10-31-14!!! Like I said, excellent customer service. Initial impression of this micro dot: solid construction; clear glass... very little tint; small size emitter at the 4:30 position. Can't wait to get to the range for some T&E fun. Oh, this micro dot rocks atop of the bundled Bobro lower 1/3 qd mount.

Great product & Great Service!


If you are like me I tend to research equipment until it's mind-numbing! I found PA by way of a forum and was impressed by the equipment, prices, reviews & customer service. I exchanged emails back & forth with Samuel about what red dot & mount would be best for me and he was right. This Red Dot is very nice, built well, has a crisp dot and simple controls. Looks and works great on my Colt M4. Shipping is lightning fast. Thumbs up PA.Edit* Just put another 100rds through my Colt M4 using this red dot. I only need a 4 setting on the indoor range and it functioned flawlessly. It is one heck of a red dot and a great bargain to boot!

becoming that guy...


I'm quickly becoming that guy. Great stuff at a low price. I show up and have all the same cool stuff as the guy who spent a fortune but I only have hundreds instead of thousands in my equipment. The red dot scope is every bit as good as the more expensive stuff at an affordable price. My buddies are jealous.

Outstanding red dot


Incredibly crisp dot, lightweight durable unit, perfect for an ak74

The Real Deal


Initial impressions ...High quality product, great price and value, fast delivery, excellent service, great people on the phone. Very helpful. Zero complaints. Will purchase again!

Great little sight for a great price


I've had EOTechs, Aimpoints, ACOGs, SRSs, RMRs, and this is by far the best little optic as far as bang for your buck is concerned. While it doesn't have the same quality as the aforementioned brands, it more than does the job and has quickly become a mainstay on my weapons.

Red dot


Love it. Took some time to dial it in, but it's perfect now!
