Key Features of the Western Rattler

1. High-Powered PCP Performance

Care & Maintenance of the Western Rattler

Proper care ensures your Western Rattler performs at its best, maintains accuracy, and has a long service life. Follow these tips for routine maintenance and handling:

---

1. Regular Cleaning

• Barrel Cleaning: Use a quality airgun cleaning kit to clean the barrel regularly. Avoid overusing solvents—just a gentle cleaning with a soft brush or pull-through cloth keeps accuracy consistent.

• Exterior: Wipe down the rifle with a soft, dry cloth to remove dust, dirt, and moisture. For synthetic stocks, mild soap and water can be used sparingly.

---

2. Air System Maintenance

• Tank Care: Ensure the carbon fiber air bottle is not exposed to extreme heat or punctured. Always check for leaks before use.

• Filling Guidelines: Fill only with high-quality compressed air or a suitable hand pump rated for PCP rifles. Avoid using CO₂ cartridges unless the rifle specifically supports them.

• Regulator Maintenance: If your Rattler has a regulator, have it serviced periodically by a qualified technician to maintain consistent power.

---

3. Lubrication

• O-rings & Seals: Apply airgun-grade silicone oil sparingly to O-rings and seals to prevent drying and cracking. Avoid petroleum-based oils as they can damage rubber components.

• Trigger & Moving Parts: A light touch of silicone lubricant keeps semi-automatic mechanisms smooth. Do not over-lubricate, as excess oil can attract dust and dirt.

---

4. Storage Tips

• Store the Rattler in a cool, dry place, away from direct sunlight and humidity.

• Keep the rifle uncocked and the air tank depressurized if storing for extended periods.

• Use a padded case or gun safe to protect the rifle from accidental damage.

---

5. Regular Inspections

• Check screws, mounts, and rail attachments periodically to ensure nothing has loosened.

• Inspect the magazine and feeding system for debris or wear that could affect performance.

---

6. Professional Servicing

• For complex issues or regulator repairs, always seek professional airgun service. Attempting to service high-pressure components yourself can be dangerous.
