Stay well clear of this company.
I ordered an air pistol with some attachments for my club from Surrey Guns over two years ago. Despite paying promptly we have not received the whole order (though after a year and a half we did get the pistol itself). I email, send Facebook messages and phone regularly. Generally this is ignored, occasionally there is an acknowledgement that the items should be sent but nothing is done.
From talking to other people in the shooting community I know I am not alone in receiving this kind of treatment from this company. Avoid if at all possible.
