ASG Scorpion Evo Hop-up Chamber - Top-Down-Center (TDC) Bracket Integration Kit
The TDC (Top-Down-Centre) Trolley Converter is designed for ASG Scorpion Evos Hop-up Chamber to radically upgrade the applicable hop-up method inside the chamber.
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.
The idea spawned originally from the TDC trolleys found on Maxx Model Hop-up chambers to achieve a perfect top-down force against the hop-up nubs. 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 a an upgrade option for the original hop-up chamber that is specifically designed for ASG gun models.
A M-nub is 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.
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.
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*
Unlocking the Full Potential of the Scorpion Evo Chamber
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 hop force to travel in a consistent downward motion without any interruptions in axial movement. Additionally, the kit includes a modified arm that applies pressure onto the trolley and M-nub for optimal performance.
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 patch.
