Q: My red-dot sight is blurry

Primary Arms is happy to exchange your sight if it is defective, but the issues you are describing are a common first impression, or may be indicative of an eye astigmatism. We reference dot shapes and blurriness in our FAQs, as does Aimpoint in their FAQ (see link below). A simple test to determine if your sight is defective is to look through your rear peep sight if you have one; that will usually clear it up.


Mount the sight on your rifle and take it shooting. Turn the brightness up only bright enough to see the reticle (this will vary based on the light level of your environment). Look straight through the sight with both eyes open and focus on the target, not the reticle. Have fun!


Here is a short list of some of the ways a Red Dot may look with astigmatism:
  1. A cluster of dots or a blob. This could be dots overlapping, or not. It can be in half size dots or other portions as well, but in general it is a group of dots that can be defined or blurry.
  2. Starbursting. This can be in conjunction with clusters. It can be radiating or asymmetrical with various “arms” in shapes or sizes. It can appear fuzzy.
  3. Abnormal shape. This can appear oval or as a line of some type. It may appear as a comma without a sharp tail.
  4. Halo around the dot. This tends to be more prevalent with folks who have had eye surgery or Lasik.


There are numerous accounts of people returning a possibly defective unit, only to find after receiving a new one that the optic appeared the same to them and their vision was the problem. With all that being said, we want you to be happy with your purchase and we’re here to help. Call us if you have any further questions.

Aimpoint FAQ



Q: What is Co-witness?

Simply, co-witness is the ability to see your iron sights through the optic's sight window. Co-witness can be confusing, so we created this YouTube video to explain the two most common positions of the iron sights in the sight window, "absolute" and "lower 1/3rd" co-witness.



Q: My Micro Dot has a canted front lens, is that normal?

Yes, by design the front lens is canted. This is required to reflect the emitter’s light back to the user in the form of the aiming dot.

Q: My order never arrived.

First, check that your order has shipped from Primary Arms and that the carrier’s tracking number shows that it has been delivered, using the methods outlined above.


Shipping times and reliability vary greatly by carrier. We have found UPS and Fedex to have good tracking systems, and US Postal Service’s systems to be less reliable.


If your tracking number shows delivered, but you did not get the package, there is not much we can do until you contact the carrier directly. For Fedex the number is 800-463-3339 and for UPS it is 800-742-5877. They are generally quite good at resolving these issues, but should they fail, give us a call. If USPS shows delivered and you did not receive the package then you will need to contact them at 800-275-8777 or we cannot file a claim. IMPORTANT: Ask to speak with the postmaster for your city directly; we have never seen an instance where anyone else cared enough or was empowered to help.


For UPS and Fedex: If your tracking has ceased to show movement on the package, and delivery has exceeded the expected delivery date by 2 business days for expedited services or 5 business days for ground services, then please give us a call or send us an email.


For USPS: If your tracking has ceased to show movement on the package, and delivery has exceeded the expected delivery date by 4 business days for Priority Mail and 7 business days for First Class Mail, then please call or send us an email and we will figure out a solution.



Q: An item is missing from my shipment.

Call us, email us, bang on our front door!!! We want to get this fixed right away. Please let us know your order number and the missing item. We are available Monday through Friday, 9AM to 5PM Central Time at 713-344-9600. Outside of business hours, please email us at info@primaryarms.com.

Q: What is your return policy?

In the rare instance a return is necessary the guidelines below will affect the return. All returned merchandise must have a Return Material Authorization number (RMA) issued by Primary Arms prior to return. Goods returned with an RMA must be in original condition and packaging and all contents and documentation must be present. Items returned without an RMA number will be returned at the shipper’s expense.


We will gladly accept return for refund any unopened and unused product. Simply return any new unused item back to us within 10 days from the date delivered. Shipping charges are not refundable. Once a scope is mounted it becomes used and is not eligible for refund, exchange or return. Placing a scope in rings constitutes mounting. For your protection, items must be returned shipping prepaid, insured for the full value and safely wrapped to prevent shipping damage.


Visit our Return Policy page to submit a return request and receive your RMA number.
