I brought a krinkov to the show to sell. I put on my sign that I wanted to see LTCH and ID or be willing to transfer. I get 10 ft inside the door and a guy stops me and wants to see it. He obviously knew a little about it. Started blowing me crap about the receiver it was on so I knew he was gonna make me an offer by his attempt so soften me up. He offered me about 100 less than my minimum I was gonna take for it. I politely told him no thanks and what my minimum was. He said he couldn't do it so I started to walk away. 20 more feet and he chases me down and says ok. We walk over and he pulls out a wad of cash and has me count it to make sure. It was all there. I then ask him for some ID or LTCH. He starts fumbling around and then finally said he must have left it in his car. As much as it killed me to hand that cash back I told him no thanks. Now what kind of guy goes to a gun show with no ID? Gunrunner, felon, paranoid? I just didn't feel comfortable selling to someone that I have no idea if they are the up and up? Just doesn't sit well with me.
