Hop-Up Units & Buckings — Controlled Spin. Extended Range. True Consistency.

Velocity means nothing without stability. The hop-up system is responsible for applying controlled backspin to the BB, counteracting gravity and stabilizing trajectory. When properly tuned, it transforms raw output into usable, repeatable accuracy.

What the Hop-Up System Actually Controls

• Backspin Application: Creates lift for extended effective range.
• Contact Consistency: Uniform pressure on the BB for predictable flight.
• Air Seal Integration: Works with nozzle and compression system.
• Bucking Hardness Selection: Optimized for FPS range and BB weight.
• Unit Stability: CNC chambers reduce lateral movement and feeding inconsistencies.

Upgrading a hop-up is not about maximum spin — it is about controlled spin. Bucking compound, nub design, barrel window alignment, and compression must operate as a unified system. When balanced correctly, the result is flatter trajectory, tighter groupings, and measurable improvement in shot-to-shot consistency.

Ideal For:

• Players increasing effective range.
• DMR and precision-oriented builds.
• Users tuning heavier BB weights.
• Owners replacing worn or inconsistent factory buckings.

For peak performance, pair with a quality Precision Inner Barrel, properly tuned Compression Components, and consistent High-Grade BBs.
