The newest version of the TechT Zero Kick Hammer for Tippmann Paintball Guns comes packaged with a new hammer drive spring. If you did not receive this drive spring and you think your marker needs it, please contact TechT. They will send you the drive spring for free. If you did not receive one, there is no need to freak out immediately. You may not need it. TechT found that some users’ markers needed a stiffer spring in order to get up to 300FPS. Most markers didn’t, but some did, so they started to include it with the hammer.
With that said, below are the instructions on how to install the hammer. Again, I would first set it up with your stock hammer drive spring. If you can not achieve high enough velocity or your cyclone is not cycling you will then need to swap out your stock spring for the stiffer one from TechT.
If you need to contact TechT for the stiff hammer drive spring please call – 901-405-1848 ex.11
