[PDI] Bull Barrel Base / Tokyo Marui VSR-10 254.5mm

*Bull barrel caps cannot be used. The screws on the bull barrel attachment are recessed slightly to securely hold the bull barrel. The bull barrel cap cannot reach the screws. Please attach the bull barrel cap to the front bull barrel.

Tokyo Marui VSR-10 compatible bull barrel base.
This is a fully CNC machined aluminum alloy barrel with a high precision. This product can be used in combination with the PDI front bull barrel, making it easy to replace the outer barrel for the VSR-10.

The combination of Front Bull Barrel P to L allows for the use of the finest heavy barrel.
This is the rear part of the Front Bull Barrel Series for the Tokyo Marui VSR-10. The threaded design allows for easy tip replacement. The O-ring on the front bull barrel joint ensures a secure fit.

*When combining the PDI Bull Barrel Base with the Front Bull Barrel Series, a Bull Barrel Attachment is required.

*The PDI front bull barrel is a model with increased wall thickness, but this product does not have increased wall thickness because the chamber is installed inside.

The screw part has a fixed pin hole.
Just like the VSR-10 stock barrel, there are screw holes for securing it to the receiver after installation. Even if the barrel is not in the exact position after fully rotating it, you can still align it and secure it firmly.

The chamber feed port, which requires precise dimensions, is carefully machined to recreate the steps and holes. This prevents burrs from getting caught and allows for smooth attachment and detachment.
Laser marking is performed near the chamber opening using the YVO4 laser marking machine "KEYENCE MD-V9920L," which has three-axis control and can recognize the Z axis in three dimensions.

About the angle with the receiver
The PDI Bull Barrel Base has been sampled from multiple VSR-10 genuine receivers and the angle has been adjusted to match the average receiver, but the strength of rotation varies depending on the batch of genuine receivers. You may need to adjust the hole that secures the chamber (red circle on the left), but this can be easily done with a file, so please try it if you have difficulty getting the angle right.

[About anodized aluminum products]
*During the anodizing process, unevenness or marks of a few millimeters may remain where the product is fixed.
*Since the screw part is inspected after the anodizing process, some of the anodizing on the screw part may peel off, resulting in silver areas, but if there is no problem with the functionality, we will treat it as a normal product.
*We have confirmed that the product can be used without any functional impact, so we do not accept returns or exchanges for cosmetic reasons.


※please note※
If you have customized your airsoft gun or replaced parts, be sure to measure the bullet speed using a bullet speed meter to ensure it is within the legal limit (possession of bullets over 0.98 J is prohibited). Also, be careful not to exceed the legal limit during the work.
