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.
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.
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:
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!
