Hello.  This is my first post on AR15.com forums.  I just wanted to announce that I got my Aimpoint Comp ML2 today.  I have mounted it onto my Bushmaster flattop receiver using the ARMS 22M68 Extended mount with the swan spacer.  I decided to get this setup based mostly on the discussions on this forum so thanks to all who contributed to those discussions.  As for the Aimpoint, I am extremely impressed.  It is the finest red dot sight that I have ever seen and it looks amazingly great on my rifle.  I will test it out at the range in a few days.  I will also post some pictures of my rifle as soon as I can get my digital camera fixed.  So thank you to everyone on this board.
