MFP Autos Posted May 22, 2020 Report Share Posted May 22, 2020 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.

Rivaltm Posted May 22, 2020 Report Share Posted May 22, 2020 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. Quote Link to comment Share on other sites More sharing options...
