PDI 6.01mm & 10mm Outer Inner Barrel for PTW M4/M16(509mm)

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 lot to lot

for the Systema PTW barrel
, please measure the outer diameter of your inner barrel using a precision measuring device such as a vernier caliper before purchasing. The

inner diameter of the genuine PTW outer barrel may vary from lot to lot.
Please ensure your outer barrel's inner diameter is 10mm or larger before purchasing.

Increased muzzle velocity does not necessarily translate to increased distance.
While this 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.
