Hi, how did you attach your silencer on your cricket , directly on the barrel or with an adapter at the end of the shroud?
I did this modification a few months ago . I remove the cap at the end of the shroud by heating with a torch to soften the époxy glue, and turning the cap at the same time. Clean the Inside of the shroud ( where the cap was) with sandpaper. Then you have to ask a good turner to make an aluminium adapter on a lathe, one side must fit very snugly in the shroud , the other end must be threaded 1/2 UNF to accept most of the silencers.
I put a Huggett moderator on my .25 Cricket ; it works fine.
