Now sorted. Thanks to all who looked!
I'm on the hunt for a BSA Supersport 5 magazine as the rifle i have bought did not come with a magazine.
New or used will be fine, and abviously the cheaper the better but price (To a certain extent) is irrelevent.
If anyone has one that they are willing to sell or knows of one for sale please can you let me know as soon as possible and PM me with a price including 1st Class Post and package! I can pay immediately with either Paypal or Bank Transfer.
