Optics-ready platform for faster target acquisition

One of the key advantages of this version is its slide cut for pistol optics. Adding a compatible red dot sight can significantly improve target transitions and sight acquisition during dynamic airsoft gameplay. This makes the Vanguard 4.3" OR an excellent option for players building a modern gas blowback pistol with red dot capability for close-range and mid-range engagements.

• Optics Ready slide for RMR-type red dot sights
• Mounting plate and screws included
• Compact 4.3" Hi-Capa format for agility and fast draws
• Excellent base for custom builds and future upgrades

Premium external construction

The Arcturus Vanguard 4.3" is built with a CNC-machined metal slide for a precise fit, smooth cycling, and long-term durability. The pistol also features a fibre-optic front sight for fast sight alignment when used without an optic. Under the barrel, a RIS accessory rail allows the installation of a flashlight or laser, giving the pistol added versatility for tactical setups.

• CNC-machined metal slide
• Fibre-optic front sight
• Steel ambidextrous thumb safety
• Steel slide catch, hammer, and magazine release
• RIS accessory rail for light or laser
• Textured ergonomic grip for secure handling

The low-profile controls keep operation smooth and intuitive, while the ambidextrous layout makes the pistol suitable for both right- and left-handed players. The rough-textured grip improves retention and control during aggressive movement and fast reloads.

Reinforced internals for reliable performance

Internally, this green gas airsoft pistol is engineered for consistency and durability. The 6.03 mm carbon steel inner barrel is treated with ENT (Enduraheat Nitride Treatment) to enhance wear resistance and performance, while key internal steel parts are manufactured through MIM (Metal Injection Moulding) and treated with the QPQ process to improve smoothness, strength, and long-term reliability.

• 6.03 mm precision inner barrel with ENT treatment
• QPQ-treated steel internal parts
• Gas system designed to function below 10°C
• SEFP magazine components for improved durability
• 100% Tokyo Marui Hi-Capa compatible parts

Arcturus states that the pistol can achieve more than 70% hits on a 30 x 30 cm target at 30 metres, underlining its strong practical accuracy. The efficient gas system is also capable of delivering over 60 shots per fill, giving the user dependable performance during extended games or training sessions.

Ideal for CQB and custom Hi-Capa builds
