Manufacturing and development:
The HopUp Unit we developed modernizes the entire AK series HopUp system to put it on par with current M4 systems. Most components of the unit are CNC machined from 7075 aluminum, with a tolerance of 0.05mm. After the production an automatic control takes place over a laser, which examines all dimensions. Through this quality assurance, this HopUp unit achieves a very high accuracy of fit.
Updates: (06.12.2022)
- The C-Clip is now included in GEN.2, which is also compatible with barrels with short milling
- The two tensioners are now more rounded to prevent damage to the HopUp bucking when set too high
- The new Offset Tensioner is already included, which is compatible with all standard inner barrels.
Compatibility with the manufacturers & variants:
The respective HopUp Unit is designed to be compatible with the manufacturer's original Nozzle. If you want to replace the Nozzle with a better one, we recommend the following lengths:
NEBO CY version (green): 19.70 - 20.00mm
NEBO EL version (blue): 20.00 - 20.70mm
Precise adjustment of the HopUp:
The HopUp effect can be very finely adjusted via the large-dimension dial with position indication. This leads to significantly more consistent shooting results. With the built-in O-ring, an adjustment due to vibrations is not possible. The surface of the adjustment wheel is designed very grippy, so an adjustment is possible even with dirty gloves.
System without limitation:
This HopUp system leaves nothing to be desired, it is compatible with normal 5mm as well as modern 7mm barrel windows and HopUp rubbers (AEG). We deliver a suitable tensioner for every wish.
The choice of barrel is also entirely up to you, normal AEG as well as hybrid barrels can be used.
Our enclosed aluminum tensioners are equipped with one of the two rubbers, here you have a hard and a soft version available. We recommend using the soft one (black) for rather lighter BBs.
The red version is suitable for 0.40g + or for appropriate Buckings which have a flatter patch.
More energy with the same spring:
Through our extensive testing beforehand, we were able to determine an average increase in energy of about 0.2 - 0.3 J., without any changes to the nozzle or spring.
Delivery includes:
- 1x CNC HopUp Unit made of 7075 aluminum
- 1x Adjusting wheel made of 7075 aluminum with position indication
- 1x cover plate made of 7075 aluminum for adjustment wheel
- 1x countersunk screw for adjustment wheel
- 2x C-Clip for AEG and Hybrid barrels
- 1x HopUp arm (lever) on 7075 aluminum
- 2x pressure spring for HopUp arm
- 1x brass screw for HopUp arm
- 1x brass ring for barrel centering
- 2x O-ring for adjustment wheel
- 1x tensioner for 5mm HopUp systems
- 1x tensioner for 7mm HopUp systems
- 1x adapter for rubber tensioner
- 2x rubber insert for tensioner - hard (red)
- 2x rubber insert for tensioner - soft (black)
Running window:
Please note the choice of the tensioner which is suitable for your barrel. For the included 5mm Tensioner the barrel window must have a minimum length of 5mm, the barrel bridge should have a width of 1,5mm.
Compatibility LCT AK 2021:
We have noticed some differences in LCT AKs from 2017 to the current 2021 models.
On the newer models, the bullet channel sits 1.2mm further back in the gun, making it very difficult for LCT magazines to go into the gun with the NEBO (CY).
Currently we recommend to use E&L magazines in this combination, these sit well in the gun and feed well.
A 20.00 - 20.50mm nozzle should be used to compensate for the gap.
If the HopUp unit is not centered on the gearbox, a thin O-ring can be placed on the back of the NEBO. This aligns the unit straight to the gearbox.
