RetroArms CNC Hop-up Unit M4 / AR15 BASIC
The CNC hop-up unit M4 / AR15 BASIC is designed for AEG replicas using the Tokyo Marui standard. The precisely machined body made of EN AW 7075 aluminium alloy provides a solid base for the hop-up system. The collet nut automatically centers the inner barrel and helps prevent it from moving during firing. The unit is compatible with most common hop-up buckings and inner barrels with an outer diameter of 8.4–8.5 mm. The BASIC version is designed for simple installation without the need to adjust the unit neck length or its longitudinal position relative to the mechabox.
Key Features

Collet Nut for Barrel Centering
The collet nut automatically centers the inner barrel and helps keep it in the correct position during firing. It is designed for barrels with an outer diameter of 8.4–8.5 mm.
O-Ring at the Unit Entrance
The O-ring at the feeding point prevents BBs from falling out of the unit when removing the magazine or reloading the gun.

Simple Installation
The BASIC version does not require lengthy adjustment of the unit neck length or longitudinal position relative to the mechabox. It is therefore suitable for players who want a precise CNC unit without complicated tuning.
