Details: Retro ARMS Hop-Up chambers have gone through several iterations, and this most recent version is the best yet.

This Hop-Up chamber is fully CNC machined and screws directly into the front end of Retro Gearbox shells, which allows for optimal nozzle alignment.

In addition, a collet tightening nut is placed in front of the Hop-Up chamber. To install, simply put the inner barrel with a bucking into the Hop-Up chamber, seal it with C-clip lock and in the end screw the collet nut it with 10 mm key into the chamber. The collet nut is manufactured from 7075 aluminum and after easy screwing of the nut, it will hold inner barrel very tight. This allows for maximum barrel stabilization. Do not use too much force to screw collet nut in, or otherwise you will damage it and inner barrel will overturn. The sign of correct tightening is less space of a gap on the collet nut.

Includes a C-clip.

Note: This chamber has a very narrow clearance for air nozzles. Most Air nozzles will not fit all the way in without modification. Retro ARMS recommends their 20.1mm nozzle for this chamber.
