FAQ Frequently Asked Questions

1. Is this difficult to install?

It is fairly simple, We recommend that you have some experience with the hop up units and inner barrel setups. Do download the instruction/ Installation manual and read all before beginning the modification process. Consult a gun tech for help if needed or contact us for any help.

2. Do I need an R-HOP patch?

Nope, this works for all types of hop setups, but we do highly recommend R-HOP buckings as minimum like the Maple Leaf Macaron buckings to take advantage of the R-hop performance for long distance shooting with deadly accuracy.

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.

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 once its installed?

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 G&G CM16 Rotary chamber only am afraid!

We have other brackets for Krytac, Prowin, KWA, ICS, and VFC, Tokyo Marui NGRS, MTW, Prometheus and Ares Amoeba.

6. What bucking would be the best?

The stock green or blue buckings 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.

Drop-in R-hop buckings like Maple Leaf Macaron are highly recommended.

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

Types of Hop-up the TDC Integration Kit can be used for

Types of Hop-up the TDC Integration Kit can be used for
The kit may be used in unison with all bucking types and also works perfectly for R-Hop & Flat-hop setups utilizing a trolley system that applies hop perfectly downwards for the most consistent pressure distributed onto the BB. As a result, increased accuracy over longer distances.

Why TDC (Top-Down-Center)?
The idea of using a Top-down-center is a well sought after functionality in airsoft that maximizes the amount of friction allowed onto a BB round and there are third party chambers that can achieve this.  However, switching to a third party chamber could carry a series of risks such as double BB feeding, misfeeding, and inconsistent air compression. That is the reason why we opted for an upgrade option for the original hop-up chamber that is specifically designed for the G&G CM16 replicas.

Advancement on the M-Nub
We tested the performance of many types of M-nubs for its firmness, durability, and ability maintain its shape under intense pressure. We settled with a version that ticks all of these boxes. 2x M-nubs are included that covers the length of the hop-up window to maximize the amount of exposure onto the bucking and then BB. This ensures the most stable hop, while the BB accelerates through the hop mound/ Arch. 

Outer Barrel Modification
Please note that this kit will require modification to the outer barrel of your airsoft replica, however, is straightforward. Full instructions on how to modify will be included in the instruction manual to download. The results are worth your while!

Unlocking the G&G Rotary's Full Potential

The TDC Converter Kit is specifically designed to ensure optimal vertical pressure on the inner barrel window of the Hop-up window.
The kit is specifically engineered to seamlessly integrate the existing hop-up chamber with precision-designed brackets. These brackets effectively guide a trolley, allowing the applied pressure on a consistent downward motion without any interruptions or axial movement.

TDC Micro Adjustment

Fine-tune the exact hop-up required for your gun build. The hop applied top to bottom creating the most stable pressure and most exposure onto the BB spin. As a result the most stable and consistent flight path.
