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.

So far so good. Looks to have great construction. Check out the torture tests on Youtube. The only down side i can see is the lens caps are not permanently attached, but it does come with covers that will not fall off.

Great Sight


So far this has been a great sight! This is my second one from Primary Arms. Clear view with quick target acquisition. Mounted on my AR15 with Primary Arms riser, make sure you get the riser to sight screws tight. Will appear tight but wiggle once mounted on rifle, had to remove and retighten, but be careful looks like could strip with too much force. They do supply thread lock which is good.

Top notch!!!


Super fast shipping. Product was above and beyond. Price and quality #1. Will buy from again

Good product and fast shipping.


Thank you so much.Good product and fast shipping.



The fit and finish on this microdot is awesome!! The dot is very crisp and clear!! Couldn't ask for a better product at this price!!!!!

Perfect for the CZ Scorpion Evo A3!


THE PA Micro dot with the MD-RBGII is the perfect red dot and riser combo for the CZ scorpion Evo A3.The micro dot is reliable and incredibly intuitive to shoot. The riser lets you use the stock CZ iron sights through the hollow base. Perfect combo.

Affordable red dot


The primary arms micro dot is an affordable investment. When you have so many firearms, it's would be a load of cash to stick an Aimpoint T1 or H1 o them all. That's where the micro dot fills the gap, similar is function and size. It holds zero on my 7.62 AK. The primary arms micro dot I have found to be the most dependable and highest quality optic in its price range.



The quality of this red dot for the price is rediclious. Solid as a rock, clear glass, crisp dot in and out of the sunlight. Getting another one asap!!

Micro dot RBGII


The scope seems built tough, compact, and seem at home on my carbine. can't wait to try it out when I go shooting. Dot is bright, and clear.

Great little micro dot


This is a great little red dot sight I put one on my AK and one on my Uzi. I cant say enough good things about this red dot. I didn't have to make any adjustments on my Uzi, it was zeroed in and spot on, right out of the box. I haven't shot the AK yet, but it looks to be really close, if not spot on zero. All in all, they are great little sights. Thanks PA team. You have a customer for life
