Maruyama (VFC) MP-IX GBB Series RIS Stock Adaptor

Modern stock compatibility with a solid mounting interface

The Maruyama CNC Aluminum 1913 / 20mm Rail Stock Adaptor for the MP-IX GBB series is a precision upgrade designed for players who want expanded stock options and a rigid, modern mounting solution. Machined from CNC aluminum, this adaptor provides a durable and stable foundation that integrates directly with the rear of the MP-IX platform. By converting the rear interface to a true 1913 / 20mm rail specification, it allows users to mount a wide range of rail-clamp style stocks commonly found on modern airsoft and training builds.

Built for modular MP-IX configurations

Designed specifically for the Maruyama MP-IX gas blowback system, this stock adaptor maintains clean fitment and proper alignment without compromising platform balance. The standardized 1913 rail format simplifies stock selection and enables fast configuration changes, supporting everything from compact setups to more stable, shouldered shooting positions. Its low-profile design keeps the rear of the platform streamlined while opening up extensive customization potential.

Durable CNC aluminum construction for GBB use

Constructed from CNC aluminum, the adaptor is built to handle the repeated stress and recoil forces associated with gas blowback operation. The black finish blends seamlessly with factory components and common aftermarket accessories for a cohesive appearance. Installation is intended for users with proper technical experience, and minor fitting may be required depending on the setup. Once installed, it provides a secure and consistent stock mounting point that enhances overall handling, control, and modular flexibility.
