Vortex Strikefire is what I decided on for my .22 upper.
Thats a pretty big red dot for a .22? Is it heavy? I wish Eotech's weren't $550.... Nice... but expensive for a .22
I don't need to spend $500 on an eotech for my .22
You don't have to. There is an eotech for rimfires that is only $400!

I have a few of these on my AR-15s and they've worked great for years under heavy use.
