Advance TDC Top-Down-Center Trolley for: Maxx Model Rotary Chamber (New Gen. All)
*Pre-Orders Available now - Product Launch Extended to May 2024 to fix some bugs*
The TDC (Top Down Centre) Trolley is designed for the Maxx Model Hop-up Rotary Chamber to incorporate the use of the extended M-nub to distribute the maximum of hop over a chambers hop-up window to improve the accuracy and consistency of the shots fired. This in turn ensures the patch can maximize its appliance on the BB for the most stable and uniform spin for the much desired R-hop performance.
The improved trolley and M-nub may be used in unison with all bucking types and also works perfectly for R-Hop & Flat-hop setups utilizing a top-down system that applies hop perfectly downwards for the most consistent pressure distributed onto the Bucking and BB. As a result, increased accuracy over longer distances.
Compatible for all New Gen Maxx Model Hop-up Chambers including:
✔ M4A
✔ M4E & M4Ei
✔ M4G & M4Gi
✔ M4i
✔ M4P
✔ M4W
✔ MGW
✔ MXW
FAQ Frequently Asked Questions
1. Is this difficult to install?
We recommend that you have some experience with R-hop builds before attempting and please download the instruction/ Installation manual before installing. Consult a gun tech for help if needed or contact us for any help.
2. Do I need an R-HOP patch?
Yes, you do or Flat-hop. There are many brands of R-hop in the market, much like Psionic, and Silent sniper that is easily available in the market as a drop-in patch. Alternatively, there are bucking available from companies like Maple Leaf with their macaroon buckings that perform much like a standard R-HOP does.
3. Should I upgrade my inner barrel?
It's not necessary as stock barrels are pretty good quality these days and could still function well with the R-HOP builds.
4. How do you remove the bracket?
It is possible, but not recommended once it is glued into place to prevent further deviations of the setup in the future. It is possible to still service your hop-up chamber and its components for cleaning without removing the TDC converter bracket.
5. Can it work on another hop-up chamber?
No. This is designed specifically for the Tokyo Marui NGRS (M4 Platform only). We have other brackets for Krytac, Prowin, KWA, ICS, and VFC.
6. What bucking would be the best?
The stock Tokyo Marui ones are good, but other brands like Prometheus and Modify brands have boundless buckings (without the bump inside) which are required for R-HOP builds.
7. Will this work for Flat-hop?
Yes, it will, and for G-hop too. There are plenty of videos of how-to and what you need for this setup. Once you have this in place, you will notice a huge difference in performance and accuracy.
8. How far can R-HOP travel?
For a 1J setup and the right settings, 60-70m using 0.28g BB
*Please note the Tokyo Marui hop-up chamber is not included - this is a specific TDC upgrade made FOR the existing Toyko Marui NGRS Chamber*
