The worst sales video I have seen in the US

[Abasmajor]

I read that many early BSA/LJ air rifles were returned to the factory as defective due to a failure of the user to understand the correct cocking procedure. If a pellet was loaded and the tap closed before cocking the rifle as in this video, the pellet would be sucked back through the transfer port into the chamber. On firing the now empty rifle, the piston would slam forwards with the pellet becoming embedded in the soft leather piston washer most likely causing major damage to the seal.

An amusing video with many incorrect statements, but given that the presenter himself admits to not knowing what he is doing, it's forgivable with the history and operation of these of old air rifles probably being a mystery to many on the other side of the Atlantic.
