Maple Leaf 2021 Transformers Autobot Silicone Hop‑Up Rubber – VSR / GBB

The Maple Leaf 2021 Transformers Autobot Silicone Hop‑Up Rubber is a premium bucking designed for VSR‑10 sniper platforms and gas blowback pistols (GBB). Built from high‑grade silicone, it provides excellent elasticity, a strong air seal, and consistent hop performance across a wide range of temperatures — making it ideal for both indoor CQB and outdoor field use.

The Autobot variant features Maple Leaf’s signature concave contact patch, engineered to increase BB surface contact and generate a more stable backspin. This results in flatter trajectories, improved long‑range accuracy, and tighter groupings compared to standard hop‑up rubbers. The 2021 Transformers edition further refines the internal geometry for better compatibility with modern VSR and GBB hop‑up units, ensuring reliable feeding and consistent FPS.

Available in multiple degrees, the Autobot series allows players to fine‑tune their setup based on BB weight and replica power. The silicone compound maintains performance even in cold weather, making it a dependable upgrade for year‑round use.
