Air Seal
Chamber Packing Hop-Up Bucking – Hard Type

As the mythical Prometheus
has delivered fire to humanity and taught us basic technology, so does
Prometheus bring us modern technical solutions for our airsoft replicas.

A hard type silicon
Hop-Up bucking was designed specially for replicas
with a muzzle velocity higher than 400 FPS. It was created with replica power
tuning in mind. Ordinary buckings do not offer
adequate “grip” on a BB at higher velocities, which negatively impacts the
range of a replica.

A hard type Hop-Up
bucking from Prometheus is not fit for use with replicas with a muzzle velocity
below 400 FPS. It is too powerful and will not allow for appropriate adjustment
of the Hop-Up system.

The set includes also
a spacer.
