Product description
Reinforcing
Gearbox System for M4/M16 Replicas
A reinforcing gearbox system is meant
to fill the empty space between the skeleton of the gearbox and the Hop-Up
chamber, thus additionally safeguarding the front of the skeleton by
transferring part of the forces acting on the body of the replica with each
piston’s operation cycle. This allows to prolong the longevity of the gearbox’s
skeleton. Installation of this module is also advisable during any significant
power tuning.
