+2 on what You Have. That said, I have no problem with the iron sight, at least yet. :wink: Yes, I have shot a few with the fancy-scmancy optics on them. Personally I have found that I'm not that fond of them, YMMV though.

For a cheap upgrade, I would recomend the Hogue grip, I just got one last week, and put it on My M4gery, even though I haven't shot it yet, I can feel the differance.
