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

"Precision" ultra-precision cylinder for VSR-10 that overturns conventional wisdom in the industry!

●Inner diameter 22φ (original diameter)
Inner diameter tolerance ±1/100mm
●SUS304 (stainless steel)
●Laser welding used
●Parallel pins used

These stainless steel cylinders are the same size (inner diameter) as the original VSR cylinders. Instead of using standard stainless steel pipes, they are cold-forged for precision, achieving an inner diameter tolerance of ±1/100mm. This is the same precision as a typical custom inner barrel. This is the ultimate cylinder series, meticulously refined with a focus on wear resistance, for bolt-action systems where efficient piston acceleration and air ejection are key.

<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.
