I’ve sold stuff for mates before and been transparent in the description that it is a friends gun. However, I’ve also explained to my friends that if it goes missing in the post or something is wrong with the rifle that they need to give the money back (in the case it goes missing) or they accept a return.
Anyways, here’s a dreamer.
Almost certainly a scammer, do your best to avoid. They say friends and family only as apparently G&S doesn’t work with their account which is a load of tosh.
