✅ Key Features
🔹 What is a TN Barrel?

A precision inner barrel that is synonymous with KM Planning. Selected brass material is treated with a unique "TN coating" to achieve an extremely small inner diameter error of 6.04mm. The manufacturing method, which unifies the electrodeposited film thickness on the hollow inner surface, boasts extremely high accuracy.

🔹 History of TN Barrel

The TN barrel is a long-selling product that has been continuously sold since its launch in 1989, undergoing improvements, and has been chosen by many users for many years as a reliable masterpiece.

🔹 HOP grooves finished one by one with an electrical discharge machine

Instead of conventional end mills, the HOP groove processing uses an immersion type electrical discharge machine. It shows excellent response to stable trajectories during full auto and precision shooting in semi-auto.

🔹 What is TN Coating?

A special multi-layer coating based on Teflon achieves the following performance:

Ultra-low friction for smooth BB bullet sliding

Resistant to dirt, excellent maintainability

Excellent durability, maintains stable muzzle velocity for a long period

🔹 Firing Performance

Due to highly accurate inner diameter management and smooth surface finish:

Stable muzzle velocity

Improved grouping of trajectories

Increased hit density during full auto

🔧 Maintenance

Due to the dirt-resistant effect of TN coating, excessive cleaning is not required. Simply wipe the inner surface lightly with a rod periodically to maintain performance for a long time.
