Beeman 2004 (P17) .177 pistol

[glam69]

As the pistol is only 6 weeks old the seller has kindly told me to return the pistol and he will supply a new replacement.

The seals for this pistol are as follows:-
BS006 Valve stem tip
BS008 Valve plug
BS009 Breech
BS117 Piston ( tighter fit than the original 2.5mm x 20mm)

Regards,
Gary

This could not be the breech seal. It is likely involved with the valve or the linkage from the valve to the trigger. It is time for a tear down.

It was the valve pin that had moved which caused the problem of not firing. Punching the pin back to the correct position and re-tightening the set screw solved the problem.

That's great to follow up with your solution, I could well help someone else down the line.
