Completely stripped, cleaned carbon etc. and reassembled this rifle.

Of particular interest is the Piston seeger, a sub component of the Piston extension part 399V.
Part 399V being two cylinders with one fitting internally to the other and the union maintained by the Piston Seeger, part 302W.

The part numbers are from the Argo-E Spare parts List Table 3 drawing.

This Piston Seeger: basically an non sprung c clip made of aluminium.

Prior to disassembly part 399V, the Piston extension and the Piston, part 412, rattled/banged against one another. The piston has a recessed area to accommodate the piston extension as a matting area. I reused the Seeger to assemble the Piston extension and mated the Piston and piston extension without the previous disjointed banging by using the seeger as a compression fitting to prevent these two parts from being disconnected and bashing against one another. Basically expanded the seeger until compression maintained the two components in a joined matted engagement.
These two items slide within the gas collector cylinder that is fixed onto the barrel.

Dam, almost sounds matrimonial or sexual, Haha.

The Question? Should the Piston and Piston extension be free of one another or was the manufacturing assembly sloppy with the two parts never being assembled/matted correctly??


Please, don't suggest I ask Benelli as I've not had success in email responses.
