I have seen those, but I have no access to a lathe. So I could only very veryyyyy carefully open up mine a little with a steel bit or something. I can max out the both hammer settings and get 750 fps at a 3k fill and get 24 shots in the 700s drops fast at 2k. But for now I have 650ish fps set up for 3 mags from 2500 to 1500 pretty good.
