Description
The Hop-Up unit is CNC Machined for precision and accuracy, and is the anodized with a red finish. The Hop-Up unit is designed to improve the performance of your rifle by improving the Air Seal and Hop-Up adjustment mechanisms of a standard until, with the strength and rigidity of a Machined Alloy Hop-Up chamber. The Hop-Up unit provides a much better Air Seal over standard hop-up units thanks to its close attention to details and production tolerances, meaning less wasted Pressure and a more efficient Air Flow. The hop-up's adjustment arm is designed to allow for small adjustments to be made, and thanks to it's clever design it will hold its place too, even after lots of shots. Overall, the hop-up unit is designed to be more stable, being stronger and tougher, with less flex than a standard hop-up unit, along with the Inner Barrel Sleeve making your rifle more consistent than before. The hop also features adjustable BB retention nubs, which are made out of rubber and hold the BB in place ready to be fired. This hop-up unit is perfect for those who are looking for the perfect Aftermarket Hop-Up unit, designed to improve the precision of your rifle, or for those who want to swap out a stock hop-up unit for something a little more special.

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.
