This modification removes the stock hopup arm / slider mechanism and replaces it with a thumbscrew that pushes down from the top. You can make insanely precise adjustments this way and tune your shooting trajectory to perfection. 


TDC 2.0 is compatible with any bucking / r-hop. This version of TDC 2.0 is compatible only with non-bridged barrels.

Our TDC's are designed to fit only a specific chamber. Here are the exact compatible chambers that this version of TDC 2.0 works with:

Genuine Tokyo Marui VSR10 chamber
JG BAR10 stock chamber
Cyma CM.701 stock chamber
WELL MB02 / MB03 stock chamber fits with modifications
Maple Leaf MLC-338 stock chamber fits with modifications
Action Army T11 stock chamber fits with modifications
CNC Action Army VSR10 chamber  different version needed
SSG10 A1/A2/A3 stock chamber  different version needed
Double Bell VSR-10 stock chamber

Lowest profile on the market

Don't have clearance for TDC you say? Our TDC requires a clearance of just 5.0mm, which means it will work even with the biggest scopes and low scope rings.

It's not going anywhere

The screw is installed in 1/2 aluminum, 1/2 undersized Nylon thread which provides the ultimate combination of durability and resistance to the screw.  O-rings and external housing provide additional resistance. Trust me - it's not moving by itself.

No epoxy gluing

We really didn't like the idea of having to permanently glue something on the outside of the barrel. That's why our TDC is an all-internal upgrade that installs inside the stock hop-up chamber and requires no gluing. For the PRO version, the external housing comes with pre-installed strong double sided 3M tape for easy installation and easy removal without damaging the gun. We even include a spare set of tape in the kit.

Vertical pressure nub system

Our TDC replaces traditional hop-up arms with CNC machined aluminum nubs that provide perfectly vertical pressure to the bucking. Each TDC comes with 3x different nubs so you can choose whichever you like the best or use the red universal nub with any off-the-shelf nub like ML Omega / Panthera / soft nub / etc.

Fool-proof installation

We made sure that our TDC 2.0 can be installed with any level of skill. We made sure that our drill jigs are usable with handheld drills, the process is dead simple and there's no way you can mess it up. 

We also have detailed step-by-step installation videos from start to finish.


PRO version provides the absolute perfection in terms of feedback and looks. The external aluminum housing provides a satisfying click to the thumbscrew that allows to precisely adjust the TDC and protects the screw from accidental bumps. It also acts as an extra safety layer to make sure the screw doesn't turn by itself.

BASIC version provides the same internals and performance of the TDC 2.0 PRO but at a more affordable price point, just without the external aluminum housing (clicking mechanism). In case you ever change your mind, you can purchase the TDC 2.0 Pro Upgrade separately at any time to get the full experience!


All of the parts in the kit, except for the drill jig, are CNC machined aluminum and Nylon (some pictures can be outdated). Everything is made to fit flawlessly together with no wobble whatsoever. They look and feel exceptional.

Required for installation:

  • drill or drill-press
  • beer (optional)

    Fixed one issue but other appeared

    First of all, easy install. Gj Tridos! Anyway I had left/right curves on the BB using AA red chamber with autobot bucking on SSG10A3. I installed the Tridos TDC, prometheus dual bore barrel and prometheus bucking all together. The curving was fixed, only straight shots! Once again gj Tridos! However I noticed inconsistency in the BB going way up or falling down way too quick. I am 95% sure that this is a air seal issue and I checked by pressing against the inner barrel on dry shot, yeah, inconsistent pressure build up on most of the shots and every 3rd/4th shot has almost no pressure. Cyllinder/piston seals and threads are fine. What’s left is the seal within the hop chamber. Im so sad it did not work out the first time after the TDC install, but rather I have to troubleshoot it. I spent a decent amount of money trying to fix the accuracy and consistency of the shots on this SSG10A3, and i was hoping to finally experience it with the TDC. Disclaimer: I believe this is not Tridos TDC issue, just wanted to point out that most likely it is not the best compatibility between this barrell/bucking and the chamber/tridos tdc. So you guys don’t make the same mistake. Hopefully Tridos guys have some info what works best. I also got the x-range bucking they offer but didn’t get the chance to try it with the chamber and TDC yet.

    Easy upgrade with good results

    This is one of the better upgrades to start with + a modify x-range 70 degree (orange) bucking you're not going to be disappointed.

    Easy to mount with even a drill bit included, you can't almost do wrong.

    You swap from a terrible original hop-up adjustment to this made of perfection.

    I promise you, you won't be disappointed by choosing this one. Go for pro version ;) the click system allows you to easy count every step of the pressure on the bucking to give you optimal and maximum result.

    I have three tridos tdc pro and would not hesitate to go for a other type when this haven't disappointed me.

    Love this TDC

    The TDC works great. Really love it. Easy to do the installation with the provided instruction. Awesome product.
