PDI 6.01mm & 10mm Outer Inner Barrel for PTW M4/M16(264mm)

Description:

The 04 inner barrel offers an excellent balance of accuracy and muzzle velocity.
This barrel features a 10mm thick outer diameter, a unique PDI innovation that reduces vibration and ensures stable shooting. Because tolerances vary from batch to batch, please measure the outer diameter of your inner barrel using a precision measuring device such as a vernier caliper before purchasing. Increased muzzle velocity does not necessarily translate to increased distance

. While the barrel is made of non-magnetic austenitic material, it may become magnetized during the manufacturing process. Occasionally, thin streaks may be visible on the inner surface, but this does not affect performance. Specifications: Total length: 264mm Compatible models: 　#SYSTEMA PTW Outer diameter: 10mm Inner diameter: 6.04mm Tolerance: ±0.002mm Material: SUS304 Please note: When customizing or replacing parts on an airsoft gun, be sure to measure the bullet speed using a bullet speed meter to ensure it is within the legal limit (possession of bullets over 0.98J is prohibited).
