The Decepticons 75º Hop Up Rubber from Maple Leaf is a high-performance hop-up bucking designed for VSR-10 style rifles and gas blowback platforms. Its specialized contact geometry helps stabilize the BB during hop application, improving shot consistency and overall accuracy.
The design features a slightly narrower entrance to improve air sealing and maintain more consistent power output. A reinforced lip with a C-clip structure increases sealing stability inside the hop-up chamber, helping ensure reliable performance during use.
With a 75º hardness rating, this bucking uses a harder rubber compound suited for higher power setups and heavier BB weights. It is commonly recommended for replicas operating in the 425–490 FPS range where a firmer rubber helps maintain durability and stable hop application.
