MR Hop 70° Silicone Hop-Up Bucking VSR/GBB – Maple Leaf

The Maple Leaf MR Hop bucking is designed to improve hop-up consistency and effectiveness in airsoft replicas using compatible VSR/GBB systems. Made from a 70° silicone compound, it features an enlarged BB contact surface that is particularly effective with heavier BB weights. The silicone material retains good flexibility at low temperatures, helping deliver more consistent performance from the first shots.

Operation and use

Unlike conventional buckings with a smaller contact point, the MR Hop profile applies pressure across a wider section of the BB. This design promotes effective backspin and can improve the handling of heavier BBs when the hop-up system is correctly configured.

The silicone compound also provides more stable behaviour in cold conditions, reducing the need for the bucking to settle during the first shots.

Compatibility

Designed for VSR-10 platforms and GBB airsoft replicas equipped with compatible VSR/GBB-profile inner barrels and hop-up components.

Before installation, check the inner barrel window geometry and hop-up chamber design. Compatibility should not be assumed for every GBB replica or standard AEG system.

Correct adjustment of the hop-up tensioner is also essential for proper performance.
