GBB Arcturus Vanguard 4.3" Hi-Capa with compensator

The Arcturus brand has established itself as a benchmark in the world of high-end airsoft thanks to its robust and realistic AEGs . With the Vanguard series, it takes a new step by offering Hi-Capa GBBs designed for demanding players, combining compatibility, precision and shooting pleasure.

The Arcturus Vanguard 4.3" GBB pistol inaugurates the first series of gas replicas from the brand, already renowned for its exceptional AEGs. This optic-ready model combines modern design, performance and modularity, with careful manufacturing and high-end materials.

• Operation: Gas Blowback (GBB)
• Firing Mode: Safety / Semi-Automatic
• Length: 230 mm
• Weight: 950 g
• Structure: CNC aluminum cylinder head / Reinforced polymer frame
• Compatibility: Standard Tokyo Marui Hi-Capa parts
• Optic Ready: pre-machined cylinder head for micro red dot type ARS-1 or equivalent
• Built-in compensator: threaded, reduces barrel lift for more stable shooting
• Sights: front and rear fiber optic
• Trigger and control: ambidextrous magazine ejection
• Picatinny rail: for accessories (lamp, laser, etc.)
• Internal: MIM steel parts, optimized sealing, improved gas efficiency
• Handle: ergonomic stippled grip in high-strength SEFP polymer

The Vanguard 4.3" is the first Arcturus GBB designed for modern tactical use: quick to learn, easy to customize and reliable in real conditions.

Its Optic-Ready design and integrated compensator reduce the transition time between mechanical and electronic sights while controlling barrel elevation for cleaner rounds.

Technical characteristics & construction

The CNC-machined aluminum slide ensures realistic recoil and superior durability. The reinforced polymer frame makes the assembly lighter without sacrificing strength. The MIM steel internals ensure long life and increased resistance to wear associated with GBB operation.

Performance, shooting and compatibility

Operating in Gas Blowback (GBB) , the Vanguard offers realistic shooting behavior and responsiveness appreciated in CQB. The threaded compensator partially redirects the gases upwards to limit the rise of the barrel and stabilize the sequence of shots. Compatibility with Tokyo Marui Hi-Capa parts facilitates upgrades (barrels, magazines, valves, springs) and adaptation to the player's preferences.

Ergonomics, controls and accessories

The SEFP polymer stippled grip provides a secure hold even in wet conditions. Fiber optic sights ensure rapid target acquisition. The ambidextrous magazine release and Picatinny rail enhance operational ergonomics for both right- and left-handed users.

Maintenance and usage advice

For optimal longevity: regularly lubricate the cylinder head and valve, check the seals for leaks and use suitable gas (with additive if necessary for cold climates). Internal charges and upgrades must comply with Hi-Capa compatibility to avoid any friction or premature wear.
