When did BSA change to 5.5mm barrels

[look no hands]

You are welcome. JB also told me that the sloping back block of the Gamo equivalent couldnt use the same component as the old Airsporters and Mercuries because BSA's subcontractor wouldnt release the tooling for that forging. Thats all I was told.
Personally the sloping back feature gave one of the best "lines" of almost any air rifle yet produced.

Hear hear, a design classic, for me culminating in the Stutzen tap loader.

Wow! Glad to know there are others who think the same as me

Possibly the company wished to continue production but Gamo would't pay the price they were asking.
