coolt Posted June 14, 2020 Report Share Posted June 14, 2020 Be aware that some (all?) MP40 threads are not concentric with the bore, causing baffle strikes. Also true for aftermarket barrels. Link to comment Share on other sites More sharing options...
Grease Gunner Posted June 14, 2020 Author Report Share Posted June 14, 2020 Good to know...I can abandon the idea of shooting suppressed unless there is a way i can determine if its concentric.Thanks for the reply Link to comment Share on other sites More sharing options...
Rekraps Posted July 9, 2021 Report Share Posted July 9, 2021 Test with a bore rod, from Brownells. You have to mount the suppressor to do so however. I use them for all guns when I mount a suppressor. Link to comment Share on other sites More sharing options...
DZelenka Posted July 9, 2021 Report Share Posted July 9, 2021 You could also use a .45 can on it. It would have to be seriously out to baffle strike one of those. Dan Link to comment Share on other sites More sharing options...
