Thank you Tyler! I e-mailed FX USA the other day and asked this specific questions, I even referenced the information on the PA website, and included a link to the FX Dreamline STX Barrel Kit for the Dream-Tac Compact in .22. I was told the information on PA's website was incorrect and that they would reaching out to PA to update their webpage. They specifically told me the DT Compact Barrel was 380mm! Based on this, I cancelled the order I had with PA! Now I'm not sure what to do! I guess that's why I'd really like to see a picture of each barrel side by side, and I'm not even from MO!
