Shreq Airsoft presented a detailed step-by-step guide on performing a "TDC Hack" to achieve perfect hop-up tuning on a sniper rifle. He demonstrated the full process by installing the modification on an SSG10 airsoft rifle.

The walkthrough focused on creating a Top Dead Center (TDC) modification for approximately $10, which can be adapted for any sniper rifle featuring a hop-up unit. He meticulously showed how to select and assemble the necessary parts, including a locknut and thumb screw, and detailed the crucial step of locating the precise spot on the rifle's outer barrel for drilling the hop-up adjustment hole.

The final steps of the guide covered removing drill burrs, properly seating the components with epoxy putty, and finally assembling and testing the newly modified rifle. He included a section outlining all the required parts to help viewers replicate the low-cost, high-performance tuning hack.
