I bet this gets posted often, but here goes. Is there a nice, decent quality budget red dot out there that's not too expensive (as in $150 give or take) that will stay zeroed and work well on an AR (556/223)? I'm thinking I'd use it for target, occasional hunting, home defense... But not much at all beyond, say 100-150 yards. I'm thinking pretty short range overall. I know I need to bite the bullet and get an ACOG or something of that quality, but honestly, I can't afford it right now. I just need something that I'll tide me over until I can sit down and buy something really decent. I guess I wouldnt limit myself to red dots. If there's a scope that fits the bill of fast acquisition and relatively short range use, I wouldn't be against it. Wanna kill these ads? We can help!
