Bolt Function
Overview
The bolt directs the paintball into the firing position and seals the breech during the air release phase of the firing cycle.
Key Points
- Controls paintball loading and breech sealing.
- Moves forward to chamber a ball and close the air path.
- Often includes integrated O rings or seals.
- Operates pneumatically or mechanically depending on design.
- Bolt speed and travel distance affect consistency and wear.
Details
The bolt serves as the moving interface between the feed system and the firing chamber. When a paintball drops into the breech, the bolt advances to push it into alignment with the barrel while sealing the chamber behind it. Once sealed, the valve releases compressed gas to propel the ball forward.
Bolts may be driven mechanically, pneumatically, or electronically depending on the marker type. They typically include O rings or low friction seals to maintain air pressure during the brief firing phase. The return motion of the bolt clears the breech and prepares the system for the next cycle.
Proper bolt design ensures minimal turbulence, efficient air use, and reduced paint breakage. Balanced bolt speed and dwell time contribute to smoother cycling and reliable performance across varying conditions.
