Watch-six,
Thanks for the info. Yes, I am aware of the size. A local gun shop has one that they let me look at. Pretty neat. My Armalite is also a flattop. It kind of sucks that it doesn't come with the flattop mount though. I couldn't really picture mounting that thing on a carry handle. How did it function for you? I am looking to shoot at targets from 100 - 200yds. I use the rifle mostly for plinking. No real precision target shooting, just looking for a replacement for the iron sights. I don't especially like the short sight radius on the carbine. I am just looking for quicker target acquisition. Thanks for responding!
