- Easy Build & Installation
- CNC Machined Aluminium
- Improved Accuracy & Range
Delivers more range and improved accuracy from your Airsoft AEG. Designed primarily for M4 AEGs but may be compatible with other AEGs that use an M4 style hop unit.
Not only does the hop unit look sweet in metallic red it performs amazingly. With a highly precise and precision tuneable rotary hop wheel you can add micro hop adjustments to any weight BB. An ideal upgrade for any Airsofter and combined with the right FPS you can easily lift up to a 0.36g BB or heavier.
Once fully built this hop unit is solid, with zero side hop arm movement your shots are far more consistent in fight path on every shot. We recommend you combine this hop unit with high quality BBs for truly outstanding results! Please note there is no hop rubber or nub included!

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.
