Disclaimer: Aside from the red dot size; 2moa and 4moa.

I am looking to get a second set of 2moa and looking at used ones. Are there any physical characteristics between the 2 moa and 4 moa that are different and unique?
Seller stating the T1 is 2moa is not good enough for me. I also don't want to buy the item and find its a 4moa.

Pictures are much appreciated. You can also email the pictures to save time posting it.
However, im sure that info is much appreciated here in the forum.

Thanks in advance.

Found some info after more research:
http://www.recoilweb.com/aimpoints-2-moa-micro-1-red-dot-optic-8393.html?__federated=1

It says 2moa versions have 2moa written on the side. I have seen reputable vendors selling aimpoint t1 2moa without "2moa" written on the outside.
I wonder if there are more signs to know.

The one i have says 2moa written on it.

Looking forward to more info.

Out of curiosity, what do both used 4/2MOA T-1’s go for on average?

I’m likely selling mine when I get back from this deployment.

If in excellent condition, with a lower 1/3 mount, you'd sell it on the EE for around $515.00 for the 2 MOA.  4 MOA's don't move as quickly.  Maybe a $475.00 price point
