Having a very difficult time choosing an optic for my 4” AR9
Eventually I’ll figure it out. I’m not asking for opinions 
When will optics manufactures realize 20mm isn’t the end all be all for old guys with bad eyesight?
Well I can attest they’re dot is bright and clear in AZ sunlight, at least the pistol model called Fox-0 has worked great on shak-awake for 2 months now. Only this rifle model I have no experience with, but ill let you know how it holds up on my 300 BO.
Trijicon and Primary Arms make larger red dots.
No doubt $$$. Primary Arms also uses an etched red dot reticle. I have 1 but can’t afford a bunch lol. Im sort of a bargan/value hunter lol. Great thing about America is every class can find a way to buy top-shelf or bargain-basement
