Chamber seal Hop-Up Bucking - soft type

When the mythical Prometheus
brought fire to mankind and taught us the basics of technology, so does
Prometheus brings us modern technical solutions for our airsoft Replicas.

A soft type of silicone
Hop-Up Bucking was especially developed for replicas
with a muzzle velocity below 400 FPS. The soft hop-up bucking of
Prometheus is an excellent replacement for worn-out Hop-Up Buckings.

A soft type of hop-up
from Prometheus is not suitable for use with replicas with a muzzle velocity of
below 400 FPS.

The set also contains
a spacer.
