Get there phone number and give them a call if you have a question. It’s super easy. Most scammers can’t hold a conversation about firearms stuff. Get on to fishing or camping or some other topic. You can tell guys that hunt and shoot in a matter of minutes normally. Figure out there location and google there area and pull up a couple of LGS that are in there area and ask them which shop they normally go to. It’s not fool proof but most scammers won’t talk on the phone.

Photos can be doctored pretty good these days. You can run a reverse image search by uploading a photo that they sent you. I have had photos come back from years ago that someone posted and a scammer used.
