Vortex stuff is good too consider them.
I bought the strikefireII It’s a 2moa covers about 6 inches at 100yards. I’ve got no problem seeing the dot in full sun on low power. 2 or 4 moa options and several optics to choose from for the application.
Imo it’s best bang for buck. Good quality lens and lifetime warranty. I’d stay away from cheap red dots.
I’ve put at least 3k rounds through my AR with vortex has held zero so far.
