Maruyama VFC ISO556 GBB Rifle - Black (2 Mags Included)

Maruyama VFC ISO556 GBB Rifle – Black (Includes 2 Mags)

Step into the next generation of modern tactical gas blowback rifles. Taking heavy design cues from cutting-edge Swiss military platforms (like the APC223), the Maruyama ISO556 GBB Rifle pairs Japanese design innovation with VFC's ultra-reliable internal gas ecosystem, delivering a hard-kicking, ultra-compact primary for players who demand top-tier realism.

Full Metal Build & Multi-Position Folding MBT Stock

Engineered around a full metal CNC-machined upper and lower receiver, the ISO556 offers real-steel weight (2.6kg) and exceptional structural rigidity without feeling sluggish during dynamic movement.

At the rear sits a folding MBT-style tactical stock complete with an adjustable cheek rest and multi-position length-of-pull. Fold the stock to the side to drop overall length down to a tiny 530mm, ideal for tight CQB cornering, vehicle deployment, or low-profile gear bags.

Toolless Front Hop-Up Adjustment & Fully Ambidextrous Layout

Forget dismantling your slide or using long allen keys mid-game. The ISO556 features an innovative dummy gas valve knob on the front gas block, simply turn the external knob to adjust your hop-up backspin directly on the field.

Built from the ground up for total ambidextrous operation, the platform includes:

• Ambidextrous Controls: Dual-sided magazine release, bolt lock lever, and fire selector switch.


• Non-Reciprocating Swappable Charging Handle: Double-sided charging handle that can be swapped to either side depending on your preferred manual of arms.

Powered by VFC Gas Architecture (2x Mags Included)

Internally, the ISO556 runs on VFC's proven M4/AR GBB system engine, delivering a heavy bolt cycle, snappy recoil impulse, and high gas efficiency on standard Green Gas.

Best of all, this package ships from BZ Tactical with 2x VFC M16A2 30-round gas magazines included right in the box, giving you £60+ of extra value out of the gate!

Technical Specifications

Pro Tip: Because the ISO556 uses VFC's V3 GBB valve architecture, it feeds flawlessly off both standard VFC STANAG gas mags and VFC VMAG polymer style mags, making loadout expansion seamless if you already run a VFC GBB platform!
