Experience a new level of precision and convenience with the TNT (THE ONE) Hop Up Chamber, engineered specifically for the Umarex GHK Glock 17 Gen 5 MOS GBBP. This meticulously crafted unit is a complete, high-performance hop-up assembly designed for a seamless drop-in upgrade, requiring only your choice of inner barrel to complete the setup.
Forged from a solid block of high-quality aluminum alloy through CNC machining and finished with a durable anodized coating, this one-piece chamber is built for exceptional rigidity and longevity. Its innovative design incorporates a rubber-covered housing that significantly enhances air-seal integrity, ensuring optimal gas efficiency and consistent FPS for remarkable shot-to-shot reliability.
The chamber introduces a revolutionary dual-side clamping system that securely locks your inner barrel in place, completely eliminating the need for traditional Jimi screws. This advanced mechanism effectively prevents barrel deformation and the risk of losing small parts, guaranteeing stable and consistent performance. For ultimate tuning ease, it includes a unique FLOT wrench for external, step-less hop-up adjustments. This omnidirectional, torque-limited tool allows you to make precise modifications effortlessly without ever having to disassemble your slide. Simply rack and lock the slide back, insert the flexible wrench into the top-right port within the ejection port, and turn right for more hop or left for less.
Ensuring broad compatibility and easy maintenance, this unit is designed to work with standard Tokyo Marui-spec hop-up buckings and a wide range of aftermarket precision inner barrels. This player-focused design makes future upgrades and routine maintenance both simple and cost-effective. Engineered for a perfect fit, this hop-up chamber installs instantly without any modifications to your pistol, offering a straightforward and significant boost in accuracy and usability for your sidearm.
