The new Wonder series of Hop rubbers features the largest contact patch ever used by Maple Leaf in their Hop-up designs. As is to be expected from Maple Leaf, the construction quality is excellent, and the Hop rubber will provide a tight airseal around your Airsoft gun's barrel, resulting in improved consistency between shots, compared to your Airsoft gun's original rubber. The new larger patch works best with heavier Airsoft BBs and is designed to provide better, longer range performance.

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!
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.
