My AR has a crap optic on it. It's one of those "I will upgrade it one of these days" but it's never gotten done. I have looked at a few options and have decided on a Vortex Strikefire II if I purchase one. I do have a Romeo 5 that I can move to it and purchase a magnifier for it. I have also thought about getting a pistol red dot and mounting on my AR with a riser. If anyone has any advice or experience I would appreciate input on what direction to go. I will say that my defensive use would be no more than 25 yards at my home due to terrain and obstacles.
