Great for $89 don't pay more - ATN Ultra Sight Red Dot Reflex Sight DTRXULSTM

I have an ARMALITE M15A4 so I have a complete flat top and but it still struggles to fit on my rail and it is out of focus at times but other options make it very deadly for whomever is on the other end of the scope- I'd take this into combat over more expensive GI Scopes(after putting a couple hundred Tungsten Rounds through first)
Pros: useability, PERFECT for clearing rooms
Cons: a bit out of focus and only one track to lock down
