- CNC 7075 Aluminium
- Includes threaded collet nut
- Compatible with AK-47/74 AEGs
If you're working on the ultimate AK AEG build, the RetroArms Precision CNC HOP-Up Chamber for AK AEGs is an integral part! This CNC machined HOP-up unit is made from 7075 Aluminium, granting it steel-like strength and flawlessly precise machining with the weight reduction perks of aluminium.
The most unique aspect of this HOP-up unit is the inclusion of what RetroArms call the "collet nut", a threaded nut which seals the gap between the inner barrel and HOP-up chamber walls. This saves you any messing around with PTFE tape and ensures your platform's air-seal is perfect, resulting in more consistent FPS readings translating to improved accuracy downrange.
The set includes everything you'll need to complete the HOP-up unit with the exception of the bucking, nub and inner barrel but will require assembly. As such, we only recommend this HOP-up unit to those confident working on Airsoft internals. Best used with the RetroArms CNC Version 3 Gearbox but compatible with almost every TM-based AK AEG on the market, the RetroArms Precision CNC HOP-Up Chamber for AK AEGs is a fantastic upgrade option for performance-oriented AK build!

Parts Fitting
Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Unique Parts
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
For more information with fitting parts, or should you require help, feel free to get in touch with our Workshop Department via our Contact Us Page.
