Description
Product Details

The TR-HOP buckings from TNT Studio represent the patented evolution of the T-HOP series, specifically designed to elevate the performance of VFC (AR/M4 series) gas blowback (GBB) rifles. This product was created with a clear philosophy: to allow players to achieve professional results with less time spent in the workshop and more time in the game.

Technical Features and Exclusive Advantages:

Increased Curved Surface (Patented): The internal design not only incorporates the advantages of the original T-HOP, but also extends the contact area ("Wider curved surface"). This allows for better wrapping of the BB, increasing the friction zone to generate incredibly efficient and stable spin.
"Drop-in" Installation (No Modifications): Unlike complex handmade R-HOP systems that require gluing and laborious adaptations, the TR-HOP installs like a standard bucking. Conventional specifications for simple, fast assembly that anyone can do.
Located & Directional: The internal geometry is designed to position the BB at the correct starting point before each shot, ensuring absolute shooting consistency.
60° Compound: Perfect balance between grip and durability for gas systems.

Tips for Optimal Setup:
Since the pressure zone of the TR-HOP is wider, TNT strongly recommends pairing this bucking with the TNT Wider Nub and S+ Double I/D Air-cushion precision inner barrels to maximize the air cushion effect and stability.
