[PDI] Palsonite Cylinder Headset for Tokyo Marui VSR-10

Precision Pulsonite Cylinder
We have developed a low-friction, highly durable cylinder that is treated with "Palsonite," a nitriding process for stainless steel that boasts the highest precision and corrosion resistance.
Low friction promotes piston speed and improved hardness maintains roundness, ensuring excellent performance over a long period of time.
The vacuum system improves airflow, making the Palsonite cylinder the perfect match for smooth air delivery.

●Inner diameter φ22mm (genuine diameter) ●Inner diameter tolerance ±1/100mm ●SUS304 (stainless steel) ●Laser welding used ●Parallel pin used
Stainless steel cylinder with the same size (inner diameter) as the VSR genuine cylinder.
These are not ordinary stainless steel pipes, but are produced using cold forging, which is known for its precision finish, achieving an inner diameter tolerance of ±1/100mm.
This is the ultimate cylinder series that has been thoroughly refined with a focus on wear resistance in the bolt action system, where the key is to efficiently accelerate the piston and eject air.

<Consideration of the connection point with the boss>
We pay close attention to the connection with the post body, which can be said to be the neck of a custom cylinder. While many cylinders use hollow "cotter pins," we determined that these do not provide the overwhelming durability required, and instead adopted "solid parallel pins." In addition, by welding the connection, we have created a cylinder that is tough enough to withstand repeated cocking over a long period of time.

*Please use end cap bolts that meet the standards sold by SPARK.
Marui genuine bolts are made to the original standard, so they have a smaller diameter than standard bolts. If you use them with a PDI cylinder, the threads may not fit. The VSR-10 compatible cap bolt standard is M4 x 12mm.
*Not compatible with genuine pistons, springs, spring guides, and cylinder heads.

※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.
