SINGLE BEST PERFORMANCE UPGRADE FOR SSG24. PERIOD.

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. 

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, regardless if you're running stock or r-hop!

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 that can be found here.

PRO vs. BASIC

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!

Materials

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.

Full Thrust?

You got it! TDC 2.0 works perfectly with Full Thrust but you will still need to drill a new hole. Conveniently, if you choose the PRO version, the housing can be installed in a way, which perfectly covers the old hole. The thumbscrew might need to be shortened a little bit due to the increased size of the bucking for the FT system.
