The hammer spring assembled with the PMI Piranha™ paintball marker is intended to provide appropriate shooting velocity
for most 

outdoor 

paintball game situations and will provide a range of velocities suitable for most conditions. Shooting

velocity will vary based upon form of regulated compressed gas or air used to power the marker, outside temperature, and
other factors. Additional hammer springs of varying spring stiffness are available for further velocity adjustment. 
DO NOT EXCEED 300 FEET PER SECOND (fps) VELOCITY.

The PMI Piranha™ paintball marker power system may be used with CO

2

, regulated nitrogen, or regulated compressed air.

Operating pressure range: 650 p.s.i. to 800 p.s.i. 

Recommended maximum input pressure is 800 p.s.i.  

DO NOT EXCEED RECOMMENDED INPUT PRESSURE. 

3. Chronograph the marker after every velocity adjustment. 

4. Chronograph the marker at regular intervals during the day, as well as any time the power source is refilled or changed, 

any time the barrel or any part in the power system is changed, and upon request of any player or game official.

Use a Barrel Plug!
