What red dot or prism ?

[bigHUN]

I want one for specific needs, about 3x to 5x magnification would be the best fit, mounting to a semi auto PCP air rifle.
I have a chance to grab one Burris RT-3 Prism, but I have a concern for parallax error also a short 2.5" eye relief. The ER shall be longer then let say 4".
The other option I am tinkering about a red dot, but again the concerns... the ordinary red dots have no magnification but the Pros are the no limit eye relief also no parallax error.
Back in time 2-3 years ago I had a Sig combo for a short time - Romeo7 and Juliet6, but got rid of them because of warranty issues.
Also, no acog or lpvo, I did try those as well.
What other modest options you can suggest a red dot with mag? No need to be fancy, I will not wear these to show up

Hawke BDC 4x or 6x comes to mind, but as much I can see these would be a Special Order in Canada.
Any other source that I miss in my search?

it will be easier to ask in the air gun part of the forum.

I agree and I am already in conversation @ agn, also reading several online reviews like pewpewtactical I am finding useful for general optics overall.
My question here was a basic in optics specifically what is available in Canada.

I may have finicky preferences but as it proved me many times during a past decade it looks like I will end up sourcing from offshore again and again.

A tactical Multi-Reticle Red Dot Sight might be my best bet, I can preset multiple ranges.
Not in hurry, still browsing the market.
