Got my Colt IUR "factory second" upper yesterday. And this isn't a thread about #####ing as I still think its a pretty good deal and I knew it would be damaged. This is going to have some cheaper parts mounted to it, but I wish they would have dropped it on the bottom.
Anyway, the damage on mine is a small piece of metal missing out of the top rail. It's to far back for a sight to cover it and to far forward for optics to cover it.
Paint? Markers?
Any tips on how to disguise this a bit?
