Man I'm slacking! Sorry about the late post on this. Anyways, some of you probably read my thread a few weeks back on me getting the AR-15 put together piece by piece. Sunday went to an outdoor range (was packed!) and got her sighted in for 25 Yards. Was pretty close to being on. I just had to go 3 clicks up and about 3-4 clicks right. Was shooting XM193 ammunition, and functioned flawlessly. Thanks to all here who gave me advice on this gun. Oh, and even though this gun is a sweet shooter, I still think I love my 18.5 inch mossberg 500s more .
