I'm shortening my cressi SL 100 down to about an 85.
I need to cut down the inner barrel and rethread the end.
I bought an M18 die with a 1mm pitch but my measuring was out, and it didn't fit the existing threads.
Can anyone @tromic perhaps? Tell me with 100 per cent certainty what the thread specifications are of the front end of the inner barrel please? Thanks.
