I recently bought a FX Leopard and before I received it, I had an epiphany. As with all rifles one of the first things I do is clean the barrel. Most of the air rifles I have owned you could remove the barrel or break barrels so no problem however, the Leopard is different and new to me. I didn't want the cleaning fluid (CLP) to get into the transfer port so I cleaned it with a patch worm with the rifle upside down. Brilliant! OK, I'm sure I didn't invent the idea lol but thought some might find this useful.
