I shot one at a suppressor shoot, which is why I ordered mine. They suppress very well actually. It's on a 10" SBR, so it doesn't make it that long. I also have a thread insert for my Beowulf, but that one is not an SBR. I am going to load up some heavy subsonics and try it out in the next week or so. I know how supers sound, but haven't run the subs. The can has a lot of volume and is about 1.75" in diameter.
Nice, will be waiting to your Youtube video
