Picked this up in a trade the other day. Unfired and the real M4 deal. Well, almost, it's semi! Interesting that the selector switch is marked Safe and Semi instead of the normal Safe and Fire... I tried and it doesn't go into that final position I'd never actually held a Colt before and even with all the Colt BS about civilian sales, I'm very impressed. I also never knew that the Military/LEO builds were totally different than the civilian line. Some pics.
