I have heard that Webley falcons are prone to their barrels breaking near the breech block. I have a theory that if this is true, that it is not actually a barrel fault but a piston fault. Falcons, like British built Diana's and Milbro's have a crappy piston set up. where the piston wears at he point the cocking arm pushes against. As this wears more and more, it gets to a point where the gun will barely cock or not cock at all eventually. I think this is the problem---if the gun is not cocking, some chimp will use more and more force and bend the barrel down. If it gets to the point where the trigger barely engages, then the barrel can flip up.
Any other thoughts on this?
