Maple Leaf MR. Hop Up Bucking for AEG - Silicone

Maple Leaf
  • Silicone construction
  • Ultra-wide R-Hop style contact patch
  • Available in several degrees of hardness

Maple Leaf has quickly risen to become the market leader in HOP-up rubbers and inner barrels, and the Maple Leaf MR bucking is their latest design for Airsoft AEGs. The MR bucking is Maple Leaf's answer to home made "R-Hop" style patches, offering similar performance but in a drop-in format without any modifications needed. The MR is constructed from silicone to provide greater resistance to the effects of cold weather. The MR bucking also helps enhance air seal, and can in some cases provide a small increase in FPS as a result of the improved efficiency. The MR bucking is optimised for heavyweight BBs (above.25g) and is designed for standard AEG inner barrels, though will produce a greater effect when paired with a Maple Leaf inner barrel or another inner barrel with a wide HOP window. The MR is designed to work with the Maple Leaf Omega Nub for the best results but can also be used with a standard nub.

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.
