Maple Leaf MR Hop 2021 Silicone AEG hop rubber - 85°
Top quality R-hop style MR hop rubber made by Maple Leaf for traditional electric airsoft guns. MR or "Maximum Range" hop rubber offers maximum range for the bullet without sacrificing accuracy.
Maple Leaf's 2021 Silicone rubber family is an updated version of their already excellent range of rubbers. The rubbers have been replaced with a silicone-based material, which improves the performance of the rubber in various temperatures. The benefits are especially evident in cool or cold weather, as the silicone retains its elasticity (and therefore its spin-giving properties) even in cold weather. Finnish autumn, here we come!
The Maple Leaf MR hop rubber has a long and wide R-hop style contact surface/hop bulge, creating a better contact area that provides a smooth and powerful spin to the ball, significantly improving the accuracy and range of the ball compared to traditional hop rubber. This also allows the use of heavier balls.
The MR rubber's feed lips, like the Super Macaron rubber, are slightly longer and thicker than usual, which provides improved sealing. It is worth noting that the correct length of the nozzle is more important in this case. An incorrectly sized nozzle can cause feeding problems.
The "normal", round/bumpy presser of a normal hop unit will press the MR rubber contact area into a curved shape, so it is recommended to use Maple Leaf's own or a similar bridge-shaped presser.
Manufacturer's recommendations for rubber selection:
Maple Leaf rubber hardness and recommended power range
50° --> less than 110 m/s (1.2 J)
60 ° --> 90-120 m/s (0.8-1.5 J)
70 ° --> 110-140 m/s (1.2-2 J)
75 ° --> 130-150 m/s (1.7-2.25 J)
80 ° --> more than 150 m/s (2.25 J)
In our own experience, our recommendations are towards 60 hardness rubber for normal outdoor weapons, i.e. up to 1.7J. The weather in Finland is more merciless (colder) even in the summer. Softer rubber plays better.
