The ultimate replacement for the original Tokyo Marui Hi-Capa 4.3 and 5.1 slide

The Viking Layer Forge Hi-Capa 4.3 and 5.1 OEM+ replacement slide has been developed as an alternative to the original Tokyo Marui Hi-Capa slide. Designed for operators who want the classic aesthetics and lightweight feel of the original design, but with the mechanical reliability required for high-level competition and real use under stress conditions.
This version replaces the factory ABS parts — prone to cracking after prolonged use — providing tripled structural durability and an optimized firing cycle.

Made from high-temperature carbon-reinforced nylon (PAHT-CF)

Manufactured entirely from PAHT-CF, an aerospace-grade engineering material, this slide drastically reduces weight compared to traditional CNC metal options, while maintaining excellent gas efficiency even at low temperatures and reducing the likelihood of cooldown.

The industrial additive manufacturing process aligns the carbon fibers in the direction of the impact loads produced by the use and cycling of the slide.

Bullnose Front Geometry

The design incorporates a Bullnose-style contour at the front of the slide. This technical modification sharpens the profile of the replica and also removes unnecessary mass from the front of the barrel, minimizing muzzle flip during rapid-fire sequences.
The result is a natural sight picture, instant target return and smooth, precise holstering with rigid holsters.

Target Acquisition with Fiber Optic Sight and Increased Rate of Fire

Each unit includes a front target acquisition system with technical fiber optic, ensuring optimal light transfer for low-light environments or fast CQB transitions.
Note: Due to its improved dimensions, the system requires the use of its own integrated front sight and is not compatible with stock iron sights.

To ensure the service life of the slide, an impact Shock Buffer for the recoil spring is supplied as standard. This component is mandatory to install; it acts as a dry shock absorber that absorbs excess recoil energy, smooths the cycle and significantly increases the replica’s rounds per second (ROF).

Engineering and National Manufacturing

Designed, tested and manufactured in Spain, the OEM+ type slide for Tokyo Marui Hi-Capa replicas represents the logical solution for operators who want to restore their secondary replica without altering the original aesthetics of the platform.

The use of the included Buffer is mandatory to prevent premature wear.

SAFETY NOTE: This product is intended exclusively for Airsoft activities. It is not suitable for use with real firearms. We recommend not exceeding the gas pressure values specified by the manufacturer. Always install the included Buffer to prevent premature wear of the internal components.
