hop up pressure arm cgs cyma gbb gbbr

Two variants of a hop-up pressure arm for an airsoft replica in the CYMA CGS system.

1. Integrated pressure nub.
2. Possibility to customize your own pressure nub.

The pin shown in the photos is made of steel (a cut nail). The plastic pin was too weak. This part is a temporary alternative to the original components, which tend to crack frequently. The plastic element wears out over time, but it is a good alternative if you need a functional replica right now.
