Finally, an external adjuster for the Action Army VSR10 chamber! It replaces the original hop arm with a nub system and click / smooth adjuster mechanism. 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. Compatible only with non-bridged barrels.

It's not the same with hopup chambers - 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:

Red CNC Action Army VSR10 chamber Yes
Gray CNC Action Army VSR10 chamber Yes
Genuine Tokyo Marui VSR10 chamber different version needed
Stock SSG10 A1/A2/A3 chamber
different version needed
Maple Leaf VSR10 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 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. The drill bit also comes with a little shelf to make the pin removal easier on the Action Army chamber.

We also have detailed step-by-step installation videos from start to finish that can be found here.


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 at any time down the road for 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)

    Couple things could be better

    The TDC could have been fully tridos designs as an option. No need for AA hopup unit and the threads could have been made out of metal somehow. But overall great.

    Best upgrade I’ve made!

    After installing the Tridos TDC 2.0 into my TM VSR-10 I’ve really come to understand that the hop up in that most important part of an airsoft rifle. It was easy to instal, and made it possible for me to just up to .43 gram bbs from the .36 gram bbs I was using before. An absolute must for sniper builds!

    I shoot lasers now

    Stock Hop before was meh.
    Installation took 15-30 minutes (disassembly not included) but overall very easy with the drilljig and tutorials from tridos.

    This TDC fixed curving BBs on AA in SSG10A3

    Reposting review under the correct item.

    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.
