PDI Bore Up Vacuum Piston for Marui VSR-10 Series

Description:

The body is made of durable "duralumin," the ring is made of durable "Delrin" with excellent sliding properties because it contacts 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 "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 producing a straighter trajectory.

*The vacuum piston cannot be used with any other than the dedicated spring guide. → Product details here

*The VSR-10 uses a special trigger system, so cocking may be difficult after installation.
