Ok fellows I jumped the gun on this(no pun intended). I went and saw it today. He admitted he had not had it out of the safe for years and said he would have sworn it said MK. Anyway, it is marked Mark but does have Property of U.S. Gov on it. He showed me his paperwork from the High Ups that states he has legal possession of it. It was in a Black hard case like the European version and had a decal on the front stating the contents. It original came with I believe a KAC supp serial number matching the gun, and a Surefire Light with integrated attachment. I have never seen a Surefire light for aMark, has anyone?
It is legit, but the thing that perplexes me is it has a barrel that sticks out 3/4" past the slide and is marked HK and a flush barrel also marked HK. He said the powers that be took the original barrel. Why, IDK? I had a hearing today and was rushed. I will get some pics and post. As soon as I can. I am hoping he will sell!
