Lowest Profile on the Market
Think you don't have enough clearance for a TDC?
Our TDC 2.0 requires only 5.0 mm of clearance, making it compatible with even the largest scopes and low-profile scope rings.
Built to Stay in Place
The adjustment screw is secured using a unique combination of:
- 50% precision-machined aluminum threads
- 50% undersized nylon threads
This provides the perfect balance of durability and resistance, preventing the screw from moving unintentionally.
Additional O-rings and the external housing provide even more resistance.
Trust us—it won't move on its own.
No Epoxy Required
We never liked the idea of permanently gluing parts to the outside of your rifle.
That's why the TDC 2.0 is a fully internal upgrade, installed directly into the hop-up chamber without requiring any epoxy or permanent modifications.
The PRO version includes a CNC aluminum outer housing with pre-installed high-strength 3M double-sided adhesive tape for quick installation and clean removal without damaging your rifle.
An extra set of replacement 3M tape is included in the kit.
Vertical Nub Pressure System
Instead of using a traditional hop-up arm, the TDC 2.0 applies pressure through a CNC-machined aluminum nub, ensuring perfectly vertical and consistent pressure on the bucking.
Each kit includes three different nubs, allowing you to choose the pressure profile that best suits your setup.
The included Red Universal Nub is also compatible with popular aftermarket nubs such as:
- Maple Leaf Omega Nub
- Panthera Nub
- Soft Nubs
- and many more.
Easy Installation
The TDC 2.0 was designed for users of all experience levels.
The included drilling jig works with standard hand drills, making installation straightforward and virtually foolproof.
It also features a small support tool that makes removing the Action Army chamber pin much easier.
For additional guidance, detailed step-by-step installation videos are available.
