Arcturus Vanguard 4.3" Hi-Capa GBB OR Airsoft Pistol with ARS-1 Red Dot Sight + Compensator
The Arcturus Vanguard 4.3" Hi-Capa GBB OR airsoft pistol with ARS-1 red dot sight and compensator is a complete, competition-inspired sidearm package built for players who want speed, precision, and premium out-of-the-box performance. This gas blowback airsoft pistol combines the proven Arcturus Vanguard platform with an optics-ready slide, factory-mounted ARS-1 reflex sight, and a metal compensator for a more aggressive look and enhanced handling.
Designed for demanding CQB, fast skirmish play, and tactical training, this Hi-Capa green gas pistol offers strong recoil feedback, refined controls, and excellent practical accuracy. With the red dot already included in the set, the user gets a ready-to-run red dot airsoft pistol straight from the box.
Complete optics-ready pistol kit
The main advantage of this version is its factory-equipped Optics Ready (OR) setup. The slide comes with a pre-installed plate compatible with RMR-footprint red dot sights, and the included Arcturus ARS-1 red dot sight gives the shooter faster target acquisition and improved aiming during dynamic engagements. This makes it an excellent choice for players looking for a Hi-Capa with red dot sight without needing additional upgrades.

Internally, this gas airsoft pistol is engineered for consistency, durability, and accuracy. Arcturus equips the pistol with a 6.03 mm carbon steel inner barrel treated with ENT (Enduraheat Nitride Treatment), while critical internal steel parts are produced through MIM (Metal Injection Moulding) and treated with the QPQ process to improve hardness and wear resistance.

QPQ-treated steel internals for long-term reliability

Arcturus states practical accuracy of more than 70% hits on a 30 x 30 cm target at 30 metres, while the efficient gas system is capable of delivering over 60 shots per fill without refilling the magazine. That makes this pistol a serious option for players looking for a reliable Hi-Capa GBB pistol that can keep up during intense matches.
