Thanks for your reply Hunter. That's good to here. I was thinking about getting the UTG after reading good reports on it but I like the looks of the Blackhawk much better. I have never seen one installed on a AR but I bet it looks cool.
Here a few pics. If want more just let me know. Its lines up with gas block n top rail great. Yea i know they say magpul flip ups will melt on gas block but i played with it hard n still no melting an still zero in perfect. ; )
