Does anyone know if B&T Impuls II-A Pistons are available?

Good Afternoon Folks,

I have some Sales Sample Impuls IIAs that I acquired and can't for the life of me figure out what thread pitch they have. I would have thought the 9mm cans would be either M13.5 LH or 1/2 x 28, but they fit neither. I'm trying to track down some replacement pistons for the can if anyone knows if and where they would be available?

Thank you and have a great weekend.

Do these use the same pistons as the current B&T USA Impuls suppressors? If so, you might try B&T USA. 

I've wondered if they will ever make alternate thread pitches available for the US units.
