Maple Leaf MR AEG hop-up rubber, 75° - red

The name of the Maple Leaf MR or "Maximum Range" hop-up rubber highlights its special feature: maximum range. The unique aspect of the MR hop-up rubber is the combination of a traditional, easy-to-install hop-up rubber with an R-hop style patch. Instead of the usual nub, it has an R-hop-like nub whose contact area completely fills the barrel window, creating a long and even contact surface for the BB. This extended contact surface imparts a strong spin on the BB with a gentler effect compared to a standard nub. The gentler spin is more consistent and powerful, allowing the use of heavier BBs. This improves both accuracy and range.

The MR hop-up rubber also incorporates innovations from Maple Leaf’s earlier versions. The front section of the MR hop-up rubber is textured like the Super Macaron, ensuring a tight seal against the barrel and hop-up unit. The lips of the MR hop-up rubber are slightly longer than usual, similar to the Super Macaron. Longer and thicker lips provide better air seal. Note! Due to the longer lips, the correct nozzle length is especially important to ensure reliable feeding.

A standard round or nub-shaped pressure arm bends the contact area of the hop-up rubber into a curve, which means the MR hop-up’s long contact surface cannot be fully utilized. We recommend pairing the MR hop-up with Maple Leaf’s own curved pressure arm to maximize performance.

Rubber Hardness Ratings

The hardness ratings of hop-up rubbers indicate their suitability for different power levels. Generally, the more powerful the replica, the higher the hardness rating should be. Below are the Taiwanese manufacturer’s own recommendations for power ranges. When choosing a rubber, consider these recommendations with some caution in northern climates, as rubber hardens in cold weather. In other words, in cooler conditions, it may be better to choose a slightly softer rubber.
