Regardless of what you do with the hop spacer, always perform a visual check by

looking through the inside of the barrel. If the hop bucking sticks too far into the

barrel, your gun will shoot the sky. You don’t want this to happen. Also note the

following:

Slippery when wet?

Humidity is the amount of moisture in the air. It is either expressed as absolute

humidity, which is the mass of water in a specified volume or mass of air, or as

relative humidity, which is the absolute humidity divided by that absolute

humidity that would make dew form at the same temperature.

To be precise, relative humidity is the ratio of the current vapor pressure of

water in the air, to the vapor pressure at which the air would become saturated

at its current temperature, usually expressed as a percentage. Saturation refers

in this context to the inability to absorb further water vapor.

Rubber is a hydrocarbon polymer, occurring as latex in the sap of a number of

plants. The major commercial source of the latex used to create rubber is the

para rubber tree.

Every manufacturer of plastic and rubber parts defines humidity levels by a

different scale but in general it can be defined as such:

Low Humidity: 0 to 40%

Mid Humidity: 41 to 70%

High Humidity: 71 to 100%

When an object rides in extremely high humidity, wet friction or suction can

occur, which will require energy to break (and therefore slows it down).

As we all know, hopup requires friction in order to generate the desired back

spinning action. Therefore, slippery surface on the hopup rubber is definitely no
