Sadly there are those willing to misrepresent anything if there's a buck/pound to be had. Always has been and always will be.

Agreed with the previous comments: buy from trusted sources or have someone who knows what they are looking at buy it for you. I'll gladly pay the extra cost and know that I got what I paid for than suffer a double loss (i.e. my hard earned money and a gun that's not safe or not what it was supposed to be).
