Q: How does a mag work?
A: Heres the steps:
1: Airtank supplies air to regulator at 800-1000 psi
2: Regulator takes pressure to 375 psi
3: Air flows through on/off valve and fills air chamber
4: Trigger is pulled first closing on/off valve and then releasing bolt
5: Bolt moves foward against spring pressure until power piston exits power tube
6: Air is released into bolt cavity and fires ball
7: Main spring returns to cocked position
8: Trigger is releaced, bolt is latched, and on/off valve pressurizes air chamber.
