I need some suggestions please. My budget is in the $100 range, and I don't know anything about them. I have a red dot sight on my CX4, but I've gotten fairly leery of it. When it's on, it's great. However, I don't want to rely on it because it blocks the sights. Battery goes dead, all I have is an expensive lens to look through. I'd like the flashlight/laser combo so that if IT dies, I can still sight through the built-in peep sights. Are there any budget-friendly, but reliable suggestions out there?
