Full description


Please note that this Madbull Blue Hopup rubber is specifically designed for AEG inner barrels but could be modified to fit other Airsoft RIFS. The rating of this hop rubber is 60 degrees and has been proven to handle any BB weight from 0.20g up to 0.36g. This is a bundle purchase where you get 2 hop rubbers and 2 nubs per order of this item. The nubs are often left out when installing the rubber sleeve into your Airsoft gun as the nubs apply allot of pressure. Experiment, mix and match your hop components to get the best out of your AEG. We recommend a minimum of 0.25g weight BB with this hop rubber.

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.

One of the best bucking I have used for sub 360fps. Superb air seal creating a big increase in FPS, range and accuracy. Due to thickness of bucking, some hop units make it a tight fit, some silicone oil will help, and you may possibly need to trim 2 mm off the end. You also get 2 buckings and nubs.
