The TTI VSR10 TDC CNC Hop Up Set is engineered for airsoft shooters who demand precision and consistency. This upgrade transforms your rifle’s accuracy and effective range through meticulous hop control and adjustability.
Key Features
- One-piece CNC-machined hop chamber – rigidly constructed for zero play and reliable shot-to-shot consistency
- TDC (Top Dead Centre) adjusting kit – enables fine-tuned, repeatable hop adjustments without field disassembly
- Compact 81cm platform – optimised for precision work and user control
- V2 Gearbox compatibility – drops into standard platforms with minimal hassle
- Accessible hop control – integrated into mock ejection port with dust cover operation
Real-World Use Cases
This hop set excels in long-range target shooting and precision milsim events where consistency defines performance. Competitive shooters benefit from TDC repeatability—dial in your hop once, log the setting, replicate it every skirmish. The rigid CNC chamber eliminates hop wobble that plagues cheaper units, crucial when dialling in 40m+ shots. Milsim players upgrading older platforms will appreciate the performance gain without extensive rewiring or gearbox replacement.

Compatibility & Upgrades
The TTI VSR10 TDC set integrates seamlessly into V2 gearbox platforms. Magazine compatibility is critical: confirm your magazines are King Arms MPX-K Sportline variants—Sig Air and VFC MPX magazines will not fit. The included 100-round magazine is supplied. Upgrade potential remains high; the modular hop design leaves room for inner barrel swaps, bucking tuning, and motor optimisation without full platform replacement.
UK Legal & Site Notes
At approximately 345fps, this hop set operates well within UK two-tone or RIF exemption windows (site-dependent). Chrono before play to confirm compliance with your venue’s power limits. The compact 81cm length makes it field-practical for CQB-to-medium-range play; check local site rules on minimum engagement distances for semi-auto precision builds. Always carry proof of age and purchase documentation for RIF exemption verification.
