PDI 6.08 370mm Inner Barrel for Marui MWS M4 GBB

Description:

When comparing barrels with different inner diameters, the key consideration is whether or not they create airflow.
As shown in the image, the 6.08mm barrel allows for a high airflow rate past the ball, resulting in a stable airflow and straight flight.
Effectively creating this flow requires a precision cold-forged stainless steel barrel.
However, a wider inner diameter alone can cause airflow irregularities that can negatively impact grouping. This
barrel is particularly recommended for rifle shots.

While it lacks the rearward thrust of a tight barrel (which tends to reduce muzzle velocity), it achieves a stable airflow for straight flight and long distance.

◎The tip of this barrel is equipped with an O-ring, just like the original barrel.

*Increased muzzle velocity does not necessarily translate to increased distance.
*Although the barrel is made of non-magnetic austenitic material, it may become magnetic during the manufacturing process.
*In rare cases, thin streaks may be visible on the inner surface, but this does not affect performance.
