Hi-Capa Vanguard 4.3″ OR with compensator – optics, reliability, performance
Want a Hi-Capa gas pistol that’s ready for a slide-mounted optic out of the box? Looking for a pistol with a lightweight, durable CNC slide with a muzzle compensator and a frame with a RIS rail for accessories? Need a powerful GBB system that works even below 10 °C? The Arcturus Hi-Capa Vanguard 4.3″ OR with compensator brings a modern Optics Ready design with an RMR mounting plate and a CNC-machined slide ending in a compensator. The ergonomic frame features a RIS rail for lights, and is made from fiber-reinforced nylon. The magazine’s polymer parts use SEFP (Super Enhanced Formulated Polymer) for excellent impact resistance. Inside you’ll find premium components, namely a steel fire-control group made by MIM with a QPQ surface finish. All stressed controls—slide stop and mag release—are steel and can be installed on either side. Precision is ensured by a carbon inner barrel with ENT (Enduraheat Nitride Treatment) finish and a 6.03 mm bore. The pistol achieves 60 plus shots per gas fill; factory tests report 7 hits out of 10 on a 30 × 30 cm target at 30 m. A key benefit is the claimed 100procent compatibility with the TM Hi-Capa standard, giving you endless upgrade and styling options (CowCow, CTM TAC, 5KU, etc.).
