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.

Awesome sight for the price


This red dot is comparable to higher end products, the dot is fairly crisp, glass is clear with less tint than the old MD06.

Best Deal for the Money


This red dot works great and why waste money on a more expensive one? If you look at the purpose of a red dot and you keep both eyes open why worry about clarity and other items that apply to scopes.

This and the QD base is a very nice setup.


This sight and the QD base is a very nice setup for a flat top AR that I like to switch between red dot and scope. Doesn't break the bank.

This fits my Budget


This sight is EXACTLY what I was looking for. A solid reliable red dot for recreational shooting.Priced right and shipped fast

Great sight


This sight performs very well ,put a 50 yard zero on my ar 15 and my pattern very closely reassembled my ballistic chart I was using . Great sight for adaptive shooting and quick target acquisition . I used a full co witness mount from PA and it worked as it should I recommended it to friends and family the very next day.

Review of PA Micro Dot


This was my first product from Primary Arms. First off, the shipping was fast. When I first open the box, I thought the product was just OK. Then the real test at the range. I was very impress with the quality of the Micro dot. The dot was very sharp and bright. The day was cloudy. I zero it in and shot 250 rds from my 9mm AR. The sights were dead on for all rds. Recommend the product for its price point.

As Usual...


This will be my 5th PA microdot purchase. Newer generation but nothing new to report. Quality far exceeds price...rugged...good battery life. ..bright dot with minimal blurring. Mounted on an AK variant and it works great.

Very happy


To begin, let me start by saying I'm a HUGE fan of Aimpoint and own one. I put together a second upper and wanted an "Aimpoint micro" without the cost and not really needing the durability it's known for. I found this. Since I won't be beating it around, I decided to give it a try. It's exactly what I wanted. If I'm ever in the market for another red dot, I'll DEFINITELY be buying a PA again. I've also recommended it to several friends who highly value my opinion. (That means when they're ready, they won't even consider anything else) You guys have a great product and an outstanding price.

Excellent Micro Dot!!


Took a roll of the dice and decided to try out the PA MD-RBGII Micro Dot. And rolled an 11 on the first roll!! Quite impressed with the build quality. Extremely clear and the red dot is visible on a bright sunny day at the 7 setting! And of course, PA service is excellent!!!
