[PDI] Vacuum Piston for Tokyo Marui VSR-10 Bore Up

Eliminates negative pressure for accurate long-distance shooting!
The body is made of durable aluminum alloy, the ring is made of durable POM with excellent sliding properties because it comes into contact with the cylinder, and the rear end is made of carbon steel because it is the part that bears the most stress and is attached to the sear. By using the right materials in the right places, we have created an ideal piston in terms of durability. Equipped with a vacuum system, it eliminates the "air pullback" (negative pressure) that occurs behind the BB bullet when fired. This prevents the bullet from spinning incorrectly, reducing collisions within the barrel and creating a straighter trajectory.

*Note: Regarding POM part colors:
Due to a shortage of raw materials (POM), it is becoming difficult to procure materials.
The color of the piston ring (POM) of the product you receive will be either white (POM) or black (POM) depending on the situation.

The design has changed from the November 2020 batch.
Changes
- Piston head design change
- Piston body design change
*There are no changes to the materials used.
*Although there has been a design change, manufacturer testing has confirmed that the initial velocity and other specifications are the same as before the design change.

*The original cylinder and original spring (thin diameter) cannot be used.
*Since the VSR-10 uses a special trigger system, cocking may become difficult after installation.
*For use with spring guides for Bore Up cylinders only.

※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.
