Calibre magazine, Vol 3, issue 6, has an interesting maintenance tip (pg 52-54) for those of us who've bought Colt IUR's:
"....when you take the rifle down you absolutely must be mindful of the recoil lug's presence. If you let it, that lug will drive itself into the front of your magazine well when you're breaking the rifle down, and if you happen to be in the habit of holding the front of the magazine well when you remove the rear take down pin, you're in for a world of hurt when that lug pivots down.
Trust us."
