The Maple Leaf Desepticons 2023 series hop-up rubbers represent the latest development in Maple Leaf’s hop-up rubber design.
The design of the 2023 series is based on the highly accurate Desepticons lineup.
Features:
- Improved BB centering in the barrel with a new design
- Includes a steel C-clip that enhances nozzle seal against the hop-up rubber. Use of the C-clip is optional.
- Support pieces inside the rubber on both sides of the barrel’s hop-up window
- Compatible with Marui / WE / KJ GBB pistols, WE GBBR rifles, and VSR-10 compatible spring sniper rifles.
In airsoft guns, a standard round nub does not work optimally with Maple Leaf’s new hop-up rubbers featuring an elongated contact patch, as the point-shaped nub bends the contact area of the hop-up rubber into a curve. This prevents full benefit from the long contact surface of the autobot hop and may cause the rubber to deform into an unintended position. We recommend using the rubber with a Maple Leaf curved nub or a curved adjustment arm for optimal performance. With GBB pistols, it is recommended to use the Maple Leaf I-Key nub.
Hop-up rubber degree rating (hardness)
The degree rating of hop-up rubbers indicates their softness. The lower the degree, the softer the rubber. Different hardness levels perform differently across various power ranges. In other words, the degree rating can be used as a guideline when selecting a suitable rubber for an airsoft gun once its power is known. As a rule of thumb, the more powerful the gun, the harder the hop-up rubber should be. The table below shows the Taiwanese manufacturer’s own recommendations for suitable power ranges.
| Hardness and color |
Recommended power range |
| 50 – green |
Below 110 m/s (1.2 J) |
| 60 – yellow |
90-120 m/s (0.8-1.5 J) |
| 70 – blue |
110-140 m/s (1.2-2 J) |
| 75 – red |
+130 m/s (+1.7 J) |
