Retro Arms collet nut for Hop-Up chambers. This collet nut is manufactured from aircraft dural EN AW 7075, which has the strength of steel and the weight of aluminum, so it is perfect for high-performance builds. Collet nut is milled on a CNC milling machine and has protective anodizing of 5µm silver color (0,005 mm).
We implemented our collet nut into every RetroArms Hop-Up chamber, manufactured till the end of 2016. It is designed only for RetroArms Hop-Up chambers.
The benefits of using collet nut are mostly for perfect seal and connection of the inner barrel with the chamber. The barrel won’t move, even when your gun has malfunctioned or when you are adjusting the hop-up.
