Modify X-Range Hop Up Bucking for GBB-VSR (55 degrees) MOD533004



Description of Modify X-Range Hop Up Bucking for GBB-VSR (55 degrees)


The Modify X-Range Hop Up Bucking for GBB / VSR-10 (55 degrees), identified by its purple color, is an evolution of the R-hop concept, engineered to maximize contact between the bucking and the BB during hop depression. Its internal structure features a Bi-Point Design that distributes pressure evenly across the BB surface, and a Special Airtight Design that enhances air retention inside the barrel, improving shot efficiency and topspin consistency.

The X-Range uses a bell-shaped geometry with a two-stage channel: a narrow, shallow section for precise BB positioning, followed by a deeper, wider section that stabilizes rotational movement. This architecture provides progressive contact—higher initial friction to generate topspin and reduced final friction for a clean, stable entry into the inner barrel. Side “wings” reinforce the barrel window, preventing depressor deformation and maintaining perfect channel alignment.

Made from high-performance silicone, the bucking retains elasticity even under extreme temperatures, which is particularly beneficial for GBB platforms where cold conditions affect gas pressure. The 55-degree hardness offers an ideal balance of control, accuracy and range with medium-weight BBs.
Additionally, the X-Range works best with the inner barrel opening shown in the additional product photo, ensuring perfect compatibility with its bell-shaped, two-stage channel design.
