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.

*Please note
This product is for the new MARUZEN CA870 HOP only.
When purchasing, please be sure to check the barrel shape of the CA870 you are replacing.
The barrel shapes of the old HOP and the new HOP are completely different.
This product cannot be installed on the old HOP.

This product has an outer diameter of 8mm around the HOP window and 8.55mm elsewhere (MARUZEN genuine barrel is 8mm). Some parts such as the inner barrel spacer may require processing when installed. In that case, please handle it yourself by processing the barrel spacer hole, etc.
*Although non-magnetic austenitic material is used, it may become magnetic during the manufacturing process.
