The Zero Kick ACT Hammer from TechT is an upgraded hammer for any Tippmann ACT gun. Because of its 58% weight reduction from the stock hammer, the Zero Kick ACT Hammer gives you much less reciprocating mass inside the gun. This means the gun kicks less and cycles faster, which will help to improve your accuracy and your rate of fire.

Now includes replacement sear springs for any Tippmann.  Use these if you encounter any double firing after installation.
