L'Antre Du Dingo checks out the TNT The One Omnix retrofit kit, designed for 1911 and Hi-Capa airsoft replicas. The kit includes an aluminum hop-up chamber, a bucking, and an inner barrel. It features a Top Dead Center (TDC) adjustment system, which allows users to tune the hop-up using a specialized tool through a small hole, eliminating the need to disassemble the replica for adjustments.

Neo035 shows the process and performance of upgrading an S&T Mosin-Nagant airsoft rifle with a complete internal kit from TNT Studio to improve its range and accuracy. He compares the stock rifle to the modified one, which features a smoother bolt action, a significant increase in power (about 100 FPS gain with an M130 spring), and an extended effective range from approximately 58 meters to 65 meters, noting that the upgrade makes it much easier to consistently hit targets at long distances.
