Although the original Worker Kunlun no longer comes with the 1.6×270mm spring, the Kunlun sold on this website will include one original 1.6×270mm spring. You do not need to purchase this spring separately when buying the Kunlun from this site. This product is intended as a replacement or spare part.

Note: Different springs perform best with different barrel lengths. Kunlun is designed around longer barrels (450–550), and shorter barrels are generally not recommended.
Do not upgrade Kunlun with the 1.6×300 Harrier spring, even if you already have them on site. Kunlun uses a 270mm spring system, and BlasterTECH notes the 1.6×300 Harrier spring is not suitable due to spring length and compatibility with Kunlun’s design. （This has not been personally tested, but the rationale appears sound.）
Performance Boost:
Stronger tension provides higher power output compared to the stock spring.
Smooth Operation:
Designed to maintain the Kunlun’s stable cycling and easy priming feel.
Durable Material:
Made from quality steel for long-lasting, consistent performance.
Simple Drop-In Upgrade:
No special tools required — install directly into the Worker Kunlun’s spring channel.
Designed specifically for the Worker Kunlun blaster.
Not recommended for other models unless confirmed by the user.
Higher-strength springs may require more priming force.
Always use eye protection when operating upgraded blasters.
Performance results vary depending on dart type, seal condition, and barrel setup.
