In the Silicone series, the MR rubber is made from a silicone-based material, improving hop-up performance in varying temperatures. Silicone hop-up rubbers stand out especially in cool or cold conditions, as silicone retains its elasticity even in low temperatures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is MR hop?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe name Maple Leaf MR, or \"Maximum Range,\" refers to 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 contact patch that completely fills the barrel window, creating a long and even contact surface for the BB. This extended contact surface imparts strong spin to the BB with a gentler effect than a standard nub. The gentler, more consistent spin allows the use of heavier BBs, improving both accuracy and range.\u003c\/p\u003e\n\u003cp\u003eThe MR hop-up rubber also incorporates innovations from previous Maple Leaf versions. The front of the MR rubber is textured like the Super Macaron, ensuring a tight seal against the barrel and hop-up unit. The lips of the MR rubber are slightly longer than usual, similar to the Super Macaron. Longer and thicker lips provide better air seal. \u003cstrong\u003eNote!\u003c\/strong\u003e Due to the longer lips, correct nozzle length is especially important to ensure reliable feeding.\u003c\/p\u003e\n\u003cp\u003eStandard round nubs in airsoft guns do not work optimally with Maple Leaf’s new hop-up rubbers featuring a long contact patch, as a point-shaped nub bends the contact area into a curve. This prevents full benefit from the MR hop’s long contact surface and may cause the rubber to deform in unintended ways.

The lower the number, the softer the rubber. Different hardness levels perform differently at various power levels. In other words, the degree rating can be used as a guideline when selecting the right rubber for your airsoft gun based on its power. As a rule of thumb: the more powerful the gun, the harder the hop-up rubber should be.
