Maruyama (VFC) ISO556 GBB Airsoft Rifle

Next-Gen Gas Blowback Rifle Built for Realism and Performance

The Maruyama ISO556 GBB Airsoft Rifle delivers cutting-edge realism and tactical performance straight out of the box. Designed in Japan and manufactured in Taiwan, this gas blowback rifle brings together robust construction, refined internals, and ambidextrous controls to provide a highly immersive shooting experience. With full metal externals, a rock-solid recoil system, and compatibility with VFC-style M4 gas magazines, the ISO556 is a top-tier choice for players seeking authenticity and field-ready durability.

Precision Engineering Meets Practical Utility

This rifle features a fully adjustable HOP-UP that can be accessed quickly via a dummy gas valve knob, letting you fine-tune your trajectory with ease. The double-sided charging handle, ambidextrous mag release, selector, and bolt catch make the ISO556 an ideal platform for both right- and left-handed shooters. Whether you're clearing tight corners or taking long-range shots, the responsive blowback system and semi/full-auto fire modes give you full control over your engagement style.

Compact Design with Folding MBT-Style Stock

Perfect for both CQB and field use, the ISO556 comes equipped with a folding MBT-style stock that reduces its overall length without compromising on stability. The rifle measures 700–770mm with the stock extended, and folds down to just 530mm—great for storage or transport. Weighing 2.6kg with an empty mag, this rifle has the perfect heft for immersive realism while remaining agile on the field.
