The tail end cap isn’t supposed to be removed- as far as I know. (I have a single digit can from them, so unless they’ve changed their design. It’s red loctite-ed in there.) The blast chamber/barrel alignment definitely not supposed to come out. You need to get a Spanner Wrench. It fits in the two “holes” on the muzzle end of the silencer. Unsscrew that cap and the baffles should slide out. I’ve used a wooden dowel to help manipulate the baffles out by pushing the dowel through the blast chamber side and pushing the baffles out of the opened muzzle side using light taps. Here is some pics to hep show.
