Modify X-Range Hop Rubber For VSR / GBB (70 Degree)

The Modify X-Range Hop Rubber for VSR/GBB (70 Degree) is a silicone hop-up bucking engineered to maximize BB contact, elevate topspin, and seal air effectively for enhanced range on VSR and gas blowback platforms. Designed for players who value consistent accuracy across conditions, it delivers a dependable hop-up performance without sacrificing durability.

• Compatibility: Specifically designed for VSR and GBB hop-up systems, optimized for a 70-degree hop profile to align with the bucking depression and inner barrel.
• Material: Made from tough, wear-resistant silicone that remains reliable across a wide temperature range, reducing bucking wear and extending service life.
• 2-Stage X-Range Channel: Bell-shaped, with a shallow entry near the loading nozzle and a deeper, wider mid-section to ensure precise BB positioning and consistent topspin.
• Air Seal & Topspin: Increased contact and friction as the BB moves from the shallow to deep channel, producing topspin while preserving a strong air seal for maximum range.
• Loading Dynamics: Bell opening widens when depressed, and “wings” bridge to the inner barrel window to hold BBs securely and prevent rear depressor deformation.
• Temperature Performance: Maintains hop-up effectiveness in low-temperature conditions, helping GBB setups stay reliable when external temperatures drop.
• Installation & Use: Easy swap for standard hop-up buckings; designed to work with common inner barrel openings used in VSR/GBB platforms for straightforward tuning.

The X-Range design, inspired by proven R-hop concepts, emphasizes maximum contact with BBs during depression to boost friction, promote topspin, and achieve a solid air seal. This combination translates to more predictable trajectories and extended effective range in field play. The silicone construction resists wear and temperature-induced degradation, so the hop-up remains consistently responsive across sessions and seasons. Ideal for players seeking repeatable accuracy on VSR and GBB platforms without frequent bucking replacements.
