  • 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.
