Stainless
Hard Cylinder Type D

A cylinder made from stainless
metal, carefully polished on the inside. Provides smooth and fast operation of
a system while reducing wear of parts and increasing the performance of
mechanisms. A ribbed external construction assures the durability of the
cylinder, whilst at the same time keeping its weight low.

Choosing the right
cylinder for the length of the internal barrel is crucial. Too much cylinder
capacity will influence the BB flight path in a negative way by making it
unstable and chaotic. On the other hand, having a cylinder with not enough
capacity will cause a “sucking” effect on the BB, thus lowering the muzzle
velocity and range of a replica.

In order to achieve
peak performance, we recommend using only high-quality oil and grease intended
for pistons and mobile parts.
