Maple Leaf MR. HOP silicone hop-up bucking for airsoft

Maple Leaf "MR. HOP" Silicone Hop-Up Bucking – for your replica

This hop-up bucking is a crucial component for the airsoft hop-up unit in VSR sniper rifles and GBB replicas. The silicone rubber imparts spin to the BB as it leaves the barrel, stabilising the trajectory and increasing range. You should replace the bucking when the current one is worn out, shows cracks, or if you want improved performance with heavier BBs.

Technical specifications

The MR. HOP bucking is made from a specially formulated silicone that remains flexible at low temperatures. The shield-shaped groove pattern on the inside provides a larger contact surface with the BB. The bucking features a narrowed black sealing ring for optimal air sealing around the nozzle. The material eliminates the cold-bore effect, ensuring the first shots are immediately consistent.

Compatibility and application

This bucking fits VSR-10 compatible systems and GBB pistols/rifles with Tokyo Marui spec hop-up chambers. Installation requires basic technical knowledge – you need to be able to disassemble the hop-up unit and replace the old bucking. The part fits directly without modifications on standard GBB/VSR inner barrels. For advanced builds using heavy BBs (0.40g+), this bucking delivers excellent results.
