Maple Leaf HOP-up Chamber for VFC/WE/TM EU-Series GBB

Maple Leaf
Code: MAP-08-030851
  • Upgraded HOP-up chamber set
  • Alloy construction w/steel HOP-up arm & alu tensioner
  • Compatible with most EU-series GBB pistols

If you want your sidearm to be capable of really reaching out, a HOP-up upgrade should be top of your list! The Maple Leaf HOP-up Chamber for VFC/WE/TM EU-Series GBB is constructed from alloy and supplied with a steel HOP-up arm and aluminium "I-key" style tensioner, promising tighter tolerances than the stock HOP-up unit which should translate to better air seal qualities, consistency and thus better accuracy downrange.

This set is compatible with VFC, WE and Tokyo Marui EU-series GBB pistols but should also fit most Tokyo Marui clone EU-series pistols, though as always, we recommend upgrade parts only for the knowledgeable and confident!

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.
