Airtech Studios TDC Trolley with M-nub (R-Hop & Flat-hop) for Maxx Hop-up Chamber

The Maxx Airtech Studios TDC Trolley with M-nub (R-Hop & Flat-hop) for Maxx Hop-up Chamber is designed for players building a more precise hop-up setup around R-Hop, flat-hop or MR-Hop style configurations. It replaces the standard trolley arrangement with a tighter, more controlled top-down-centre contact, helping the applied force stay even across the patch instead of shifting or tilting inside the chamber.

In practical use, that means more consistent BB spin from shot to shot, which is exactly what matters when you are trying to tighten groupings and get the best from an R-Hop build. The enlarged front contact area helps cover more of the hop window for a more uniform press on the bucking, while also improving window coverage for a better air seal.

The included M-nub is designed to work closely with the trolley and uses a flexible 3M adhesive backing to maintain proper contact at the trolley foot. It is especially well suited to users running Flat-hop setups, Maple Leaf Super Macaron MR-Hops, or dedicated R-Hop patches in compatible Maxx chambers.

This TDC trolley is compatible with selected Maxx CNC aluminium hop-up chambers for M4 and SCAR platforms, including ME, MI and SV series variants. For a well-matched build, it also sits naturally alongside hop rubbers and inner barrel upgrades from the Airsoft Parts range. Add it to your build when you want cleaner, more consistent hop application from a Maxx chamber.
