TDC Hop Up Chamber | Umarex/VFC/Walther PDP | Black | TTI

This hop-up unit from TTI Airsoft is a TDC (Top Dead Center) hop-up chamber for the Walther PDP series GBB (gas blowback) replicas. The TDC adjustment allows you to tune the hop-up from the top, enabling more precise spin control on your BBs compared to a standard adjustment system. You use this airsoft hop-up when you want greater control over your hop-up setting for more consistent flight and effective range during skirmishes. The fully CNC-machined construction makes this unit a direct upgrade for players looking to fine-tune their PDP platform further.

Technical specifications

This hop-up chamber is CNC-machined from a single piece of 7075 aluminium, resulting in a solid and dimensionally stable construction. The finish is black anodised and features the V-PDP and TTI Airsoft markings on the side. The one-piece design keeps the inner barrel and hop-up rubber securely in place. The TDC adjustment mechanism is located on the top, allowing you to access the hop-up from above.

Compatibility and application

This hop-up unit is designed for the Walther PDP GBB (gas blowback) replicas and is compatible with models from Umarex, VFC, and Walther PDP. The unit is suitable for players looking to fine-tune their replica further and fits within both standard and advanced GBB builds. Installation requires disassembling the top of your replica and opening the hop-up section, so some experience with GBB platforms is recommended.
