112mm S+ Omnix RETROFIT KIT for Hi-Capa

T-N.T. OMNIX HOP-UP Set is a modern upgrade hop-up chamber for gas pistols of the Hi-Capa / 1911 / 2011 type, compatible with Tokyo Marui specifications.

The main advantage of this system is its innovative design, allowing Hop-Up adjustment without removing the slide, which significantly speeds up tuning directly during gameplay or testing.

The heart of the system is a smooth TDC mechanism (Top Dead Center), which applies even pressure to the hop-up rubber. Compared to traditional designs, it eliminates uneven force distribution and contributes to more stable BB rotation, higher accuracy, and more consistent shooting performance.

The hop-up chamber is made from a single piece of CNC-machined aluminum, ensuring high strength, precise alignment, and improved air seal. Precise barrel guidance also helps minimize vibration and improves overall performance consistency.

The package also includes a practical aluminum knurled adjustment key, allowing fine Hop-Up tuning from the outside without disassembling the pistol. Specially treated anti-slip screws resist loosening caused by vibration during shooting, ensuring long-term setting stability.

The system uses a unique T-Lock design, which supports barrels with both wide and narrow cutouts, and thanks to the included L-Spacer adapters, it is compatible with frames from various manufacturers while maintaining quick disassembly functionality.

The chamber is designed according to Tokyo Marui specifications and is compatible with most Hi-Capa / 1911 / 2011 pistols. Due to manufacturing tolerances between brands, minor fitting may be required in some cases. Therefore, this upgrade is recommended especially for experienced users or professional installation.

CNC Hop-Up Chamber

The aluminum CNC chamber is made from a single piece, ensuring high strength and durability. At the front sides, set screws secure the barrel in place, preventing rotation and keeping it firmly fixed inside the chamber.

Unlike traditional systems, Hop-Up adjustment can be made directly from the bottom of the chamber (using a 1.5 mm hex key) without removing the pistol slide, significantly improving convenience and efficiency. The pressure is applied via a TDC system — a wide pressure roller applies force perpendicularly to the bucking, ensuring even pressure distribution across the entire hop-up rubber surface.

Solar Eclipse (S+) Barrel

In a standard barrel setup, as the BB passes through the hop-up contact area, it is pressed against the lower part of the barrel, increasing friction and reducing hop-up efficiency.

At the beginning of the S+ barrel, in the hop-up contact area, there is a micro protrusion on the lower side of the barrel (height 0.04 mm), which slightly lifts/centers the BB inside the barrel and reduces friction during the initial phase of firing. This allows more efficient use of the hop-up system, resulting in greater spin with minimal energy loss.
