PDI VSR-10/Pistol W Hold Chamber Packing (70deg)

A new series, unlike the softer "hardness 50" type, a "hardness 70" hardness setting is added to the lineup of our well-established PDI-made W hold chamber packing.

Accuracy is improved by 2 points holding the BB
The biggest feature of PDI packing, W hold, is retained. By cutting a notch in the rib center, BB pellets are held at 2 points, resulting in a straight trajectory. Accuracy is also improved. Since the hardness is set at 70, even under higher temperatures such as summer, constant hardness is maintained.

Ring ribs are set in two places, improving air tightness
Two ring ribs on the outside increase the adhesion with the chamber, resulting in excellent air seal. It also helps to position the chamber packing itself and sustain it in the best condition.

Best position for BB in VSR-10
The best position for the BB pellet proposed by PDI is slightly in front of the center of the HOP rib. Since the hop ribs are in contact with the BBs at the standby positions, stable flight is achieved.

High-quality nitrile packing made in Japan
Domestically produced nitrile rubber, which is not easily affected by temperature and has good durability, oil resistance, abrasion resistance, and tear strength, was chosen. Compared with the conventional 50 hardness type, delicate handling is required in the winter. However, it is able to get good performance out of heavier pellets.
