Description

《Information》

As shown in the image, 6.08mm has a large amount of air flow that overtakes the bb, this creates a stable air flow around the bb and keeps accuracy.

If the inner diameter is only made wide, the air flow might become rough and adversely affect the grouping.

A precision stainless steel barrel made by cold forging is required to effectively create this flow.

Although it lacks the momentum of air pushing it out from behind like a tight barrel (the initial velocity tends to decrease),

it achieves good accuracy and a long flight distance because of the bb riding on stable air flow.

It’s not so tight, This barrel keeps libration after trigger release low, and it rise up accuracy.

※The increase in FPS and range are not proportional.

※Laser marking and engraving variations depends on the production lot.

※Although a non-magnetic austenitic material is used, magnetic force might be induced during the manufacturing process.

※In some rare cases, a thin striped pattern can be seen on the inner surface, but this does not affect performance.
