Retro Arms CNC Aluminum Rotary Hop-Up Chamber Unit for AEG V2 M4/M16 - Silver (GG07-04)

The Hop-Up chamber features a new pressure-adjusting system. Basic plastic gears were replaced with a single large POM one. The adjustable gear has a serrated surface for better fine-tuning and eliminates slipping.

A collet tightening nut is placed in front of the Hop-Up chamber, which allows for barrel stabilization.

To install, simply put the inner barrel with a bucking into the Hop-Up chamber, seal it with a C-clip lock, and screw the collet nut with a 10mm wrench into the chamber. The collet nut is manufactured from 7075 aluminum, and after screwing the nut, it will hold the inner barrel tightly. Do not use too much force to screw the collet nut; otherwise, you will damage it, and the inner barrel will overturn. The sign of correct tightening is less space of a gap on the collet nut.

Includes a C-clip.
