I never heard of any updates. I had 3 and sold them all due to cycling problems. Seems like they're hit or miss. For every 1 I hear about that has cycling problems, someone else says theirs runs perfect. I really loved that gun, and hated to let them all go, but mine wouldn't cycle anything and I tried just about every TSS available. I had one that was fine for over a year and a lot of range time, then just mysteriously quit cycling. Very disappointing, but I don't have the time, money, or patience to deal with faulty guns. All of mine were meticulously taken care of, so I don't know what the issue is other than I believe them to be over gassed with TSS. They all shot fine with target loads. The only fix I've heard was posted earlier in this thread, and that is to have the gas ports manipulated.
