The Maple Leaf Autobot 2023 series hop-up buckings represent the latest development in Maple Leaf’s hop-up bucking design.
The design of the 2023 series is based on the proven original Autobot series. The most distinctive feature of the Autobot series is its long, hourglass-shaped curved hop-up nub, which can provide strong spin even for heavier BBs.
Features:
- Improved BB alignment in the barrel with a new design
- Includes a steel C-clip that enhances nozzle seal against the hop-up bucking. Use of the C-clip is optional.
- Support pieces inside the bucking 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 rifles.
In airsoft guns, a standard round nub does not work optimally with Maple Leaf’s new buckings featuring a long contact patch, as the point-shaped nub curves the contact area of the bucking. This prevents full benefit from the Autobot hop’s extended contact surface and may cause the bucking to bend into an unintended position. We recommend using the bucking with a Maple Leaf curved nub or a curved adjustment arm for optimal performance. For GBB pistols, it is recommended to use the Maple Leaf I-Key nub.
Hop-up Bucking Degree Rating (Hardness)
The degree rating of hop-up buckings indicates their softness. The lower the degree, the softer the bucking. 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 bucking for an airsoft gun once its power is known. As a rule of thumb, the more powerful the gun, the harder the hop-up bucking should be. The table below shows the Taiwanese manufacturer’s own recommendations for bucking suitability across different power levels.
| Hardness and Color |
Recommended Power Range |
| 50 – Green |
Under 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) |
| 80 – Red |
140+ m/s (over 1.8 J) |
