This hop-up chamber unit by TNT is engineered specifically for the Tokyo Marui Hi Capa/ 1911 GBB Airsoft Pistol Series. Crafted from high-quality aluminum alloy through precision CNC machining, it features a durable sandblasted and anodized finish for exceptional resilience and a refined appearance.
The innovative design includes a patented steel TDC (Top Dead Center) ring with stepless adjustment, allowing you to fine-tune hop-up effortlessly from the bottom of the unit?no need to remove the slide during operation. Simply rack and lock back the slide, insert the included 1.5mm hex wrench into the ejection port, and adjust with ease: turn right for more hop, left for less.
An anti-slip screw surface ensures the setting remains secure even during prolonged use, preventing loosening due to vibration. The upgraded dual-side clamping mechanism replaces traditional screws, offering precise alignment while minimizing part loss and deformation.
This chamber-only version comes equipped with a TL-HOP bucking and is compatible with most Tokyo Marui-spec buckings and precision inner barrels (sold separately), making it an ideal upgrade for enthusiasts seeking enhanced accuracy and consistency.
