What type of sights do you prefer and why do you prefer it. I like iron sights but there are so many options availabe for the AR platform I would like to try a few to augment with the irons. I would like to have a scope so I can shoot tighter groups out further yet be able to point and shoot with iron's. Ive looked through halo sight and the more I think about it it seems usless (why not use the irons). Anyway just looking for some of you opinions and here why you back up that choice for you. Thanks guys!
