Cometa Orion Breech Bolt Group – OR200003
The Cometa Orion Breech Bolt Group is a replacement loading and breech-closing assembly for selected Cometa Orion PCP air rifles.
The bolt group works with the rifle’s cocking mechanism to collect a pellet from the magazine or single-shot tray, guide it into the barrel breech, and close the action before firing. Correct bolt movement and alignment are important for smooth loading, reliable breech sealing, and consistent performance.
This is the assembled service group identified by part number OR200003. It must not be confused with the individual bolt shaft listed as OR000003.

Installation Information
PCP air rifles contain high-pressure compressed air. Ensure the rifle is unloaded and fully depressurised according to Cometa’s instructions before removing internal components.
Installation should be completed by a qualified PCP airgun technician. The assembly must align correctly with the magazine, pellet channel, transfer port, and barrel breech.
Incorrect installation may cause:
- Difficult or rough loading
- Damaged pellets
- Breech air leakage
- Inconsistent velocity
- Magazine-alignment problems
- Damage to internal receiver components
Do not grind, drill, bend, or otherwise modify the assembly to force compatibility.
