Thank you gentlemen;
I have had the A5 apart several times for a thorough cleaning. However, I thought maybe it was just a drop-in of a different lifter. Not worth it for me.
Leave it as is . . .good advice and taken!
Funny how even the big shot gun writers don't even understand A5 functioning. They say the fired shell is pulled from the chamber when actually the barrel moves forward off the shell which is still held on to the retracted bolt by the extractor and then kicked out by the ejector on the barrel extension.
Certainly a grand old gun.
