Ordered a Vortex Strikefire from Cabela's and got it yesterday. Is the "DOT" suppose to be round and solid? The dot in the one I got does not resemble a dot, or anything circular what so ever. Even at the lowest brightness settings, the "DOT" is anything but a dot. The only way I can really describe it is a snowflake or starburst, there is no clear border, it is like a red or green hair kind or rolled up losely in a ball. I know this an "affordable" sight, but I was expecting a red/green dot scope to have a round, circular "DOT".
Very disappointed. Need return information, I will try another one, but if it is the same, I will have to fork out the extra cash for an Aimpoint.

It's not the optic. It's probably you.

Google "astigmatism red dot".

I have 20/20 vision.

That doesn't mean you don't have it.

You aren't the first to have this exact same problem.

Edit:
Have you tried using other red dots before?
This would be a good way to rule out your eyes.

I have not used other red dot scopes, think I will go to my local gun shop on Friday and look through some before I send this back. Thanks.

Hope it works out for you. I shot mine today, the thing is great. I have 500 rounds through it without having to adjust the zero.



I can get clays at 100 yards usually on the first shot.



My buddy knocked his scope loose today too. I handed him my rifle and he was pinking cans at 60 yards, no problem.

A common problem that a lot of people have is astigmatism, and it causes them to see any red dot in strange shapes. Here are some tests that you can try to determine if it's your eyes or the sight:



1. Look through the scope with your other eye. If the dot changes shape,
it's probably your eyes. If it looks exactly the same that could
indicate it's the sight.





2. Rotate the sight about it's optical axis while looking through it. If
the irregular shape of the dot rotates with the sight then it would
indicate it's the sight. If the shape maintains its orientation, it's
probably your eyes.





3. Let another person look through it and see if they see the same
shape.





4. Try photographing the dot and see if it looks the same in the photo
as what your eyes see. A photographic lens should be well corrected for aberrations, so it should appear nice and round (assuming you get it focused correctly).





If doing any one of those tests seems to confirm that it might be the
sight then just give us a call at 1-800-426-0048 and we will gladly send
you a new one. If it's your eyes, then unfortunately there isn't much
we can do.





I hope this helps. If there is anything else we can do for you just let
us know. Thanks!

I had my girlfriend look through the scope and I asked her what see saw and her response was a snowflake type image. I also see a reflextion inside the scope from the 6-9 oclock position, if I rotate the scope, the reflection rotates along with the scope. I want to send this back and try another one, something isn't right with my scope.

That's fine. just give customer service a call and they should be able to take care of it for you. 1-800-426-0048.



Let me know if you need anything else. Thanks!

I left a message with customer service and got a very prompt call back. The customer service rep was top notch. Will send scope back today and hope for fast turn around. Thanks.

Dude, it's not the scope. It's you, trust me.

I have astigmatism and I only found it out because of the Strikefire.

I could describe it EXACTLY in your same words. Snoflake and all.

Just take a picture of a random background, with the red dot in between. Focus on the background, not the red dot body.

A camera won't lie.

OK, I sent the scope in last Friday and got a brand new scope yesterday. The customer service really is top notch. The bad news is the new scope looks just like the old scope, so I guess it must really be my eyes
ohhh nooo.

My scope was a dot and it is now a "cluster of grapes" i need to send it in but it took so long to zero it i dont really want to do it again but i guess i will have too.

My red dot does the same thing if I focus on the dot. Focus on the target.

Just an FYI- The is taken from the website of a company that sells $700 Red Dots:




The dot in my –––––––– sight doesn't look round. Is it defective?


   If your dot does not appear to be perfectly round, the distortion is probably caused by the way that your eye perceives the dot, rather than by some mechanical defect. Due to differences in the lenses in different individuals' eyes, round objects that subtend areas near 3 minutes of angle may appear distorted in a variety of ways depending on the individual and other environmental influences. Inexpensive red dot sights sometimes have manufacturing defects that can cause the dot to be an odd shape.

   A simple test that can be easily performed will allow you to determine the cause of the apparent distortion:

       * Turn the sight on and look through as you normally would. (This test is easiest when the sight is not mounted on a firearm, but can be performed with the sight mounted as well. Just make sure that the firearm is unloaded and pointed in a safe direction.)

       * While continuing to look through the sight, roll the sight on its optical axis.

       * If the dot's irregularities seem to revolve around the center of the dot like the spokes of a wheel, there is a mechanical defect causing the distortion.

       * If the dot does not roll with the sight, the distortion is caused in the way your eye perceives the dot. This is not to say that you don't have good vision. You can see clearly and still see a distortion in objects this small.


   This effect is less pronounced in sights with larger dots. More people will see the dot in a sight with a 10 minute-of-angle dot as being perfectly round than will be able to see a 3 MOA dot as round.
