G&G Cold-Resistant Hop-Up Rubber

The G&G Cold-Resistant Hop-Up Rubber is a fairly soft bucking that is perfect to use in the winter period because it can withstand the cold.

When you play in temperatures around freezing, the bucking can become stiffer which eventually causes the hop to become less tunable. By putting a softer bucking in your airsoft replica like this bucking from G&G, you avoid this problem.

This bucking is fine for use with bb's of 0.20 - 0.30gr.
It is not recommended to use this bucking in a DMR because the forces with which the (usually heavier type of bb's) are subjected are so high that the bucking will be destroyed faster.
