TDC Hop Up Chamber | Umarex/VFC/G17 Gen5 MOS | Black | TTI

This hop-up chamber from TTI Airsoft replaces the complete hop-up unit in your Glock GBB pistol and determines how the BB receives spin upon leaving the barrel. The TDC (Top Dead Center) design allows you to adjust the hop-up not only vertically, but also horizontally, enabling you to align the spin more precisely. Whether you are fine-tuning your platform or experiencing inconsistency with your airsoft hop-up, this chamber is a logical step towards tightening your groupings.

Technical specifications

This hop-up chamber is fully CNC-machined from a single piece of 7075 aluminium. The finish is black, with clear markings (UMV-GK-Gen.5-MOS and TTI Airsoft) on the housing. The knurled adjustment wheel on the underside provides a tactile, stepped adjustment of the hop-up. The TDC mechanism on the top controls the vertical pressure on the bucking.

Compatibility and application

This hop-up chamber is designed for Glock-platform GBB pistols and is compatible with replicas from Umarex, VFC, and the G17 Gen.5 MOS. The unit is aimed at airsoft players looking to further fine-tune their pistol towards an advanced build. Installation requires disassembling the slide and inner barrel, so some experience with field-stripping a GBB pistol is recommended. If you prefer to work alongside a team member who has done this before, that is never a bad idea for a first attempt.
