I’ve been working on this R&D unit for a little bit and finally took it out to try today. This is my own Swedish K suppressor I made to go along with the m/45SA semi auto guns I’m planning to build. This one is the “short” version but I plan to make a longer one as well. Overall length is 8.750” with a 5” ported barrel and 5” baffle stack. My plan now is to do one as a 12” unit and increase the baffle stack to 8.25” using the same barrel.
