A high quality performance aftermarket hop up for Tokyo Marui Airsoft M4 / M16 series AEGs.

Full description


This package comes included with everything you will need to get it installed and working; C-clip, hop rubber, nub and the spring for the front of the unit are all included in this bundle.  The hop unit is made of polymer, providing a small amount of flex in the unit for optimal performance as some believe a stiff metal hop-unit that does not flex is more likely to miss the odd round. This is a traditional side dial adjustment hop unit, so should be nice and familiar to those that haven't messed around with an aftermarket hop unit yet.


  • Small amount of flex
  • Comes with all required components
  • Excellent quality finish
  • For Marui M4 / M16 series
  • Hop spring, C-clip and nub included
  • All necessary screws and retention clips are included

Package Includes:

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.
