Okay so I was doing some browsing over at QRF's page, and I saw that the Huntertown Arms Guardian 9 is warranted for subsonic 300 blackout. Does anyone have any feedback on this? I know people say to not try to do too much multi-purposing, but if it is a viable option, I could cover down on silencing 3 different weapons for the price of one AAC can. stamps included.
