Congratulations on your new T2, if you are like me it will not be your last CCM.
Aside for the normal “Autococker” stuff like a regulator tester and valve tool, there are a couple thing you need to get for your T2; a #10 Torx head and a Stormin Norman Slot Blocker.
The Torx head is to remove the Top-Tube for cleaning and to replace the O-ring detent. The Slot blocker goes on to the back-block and shields the hammer slot, keeping the bottom tube cleaner, which keeps the velocity more consistent.
