AEX Custom THE ARENA KING — Tokyo Marui Hi-Capa 4.3 Gas Blowback Pistol — Custom Hi-Capa (4.3 Platform)

The AEX Custom THE ARENA KING is a full-build showstopper and competition-ready Hi-Capa tuned for fast splits, point-and-shoot speed, and rock-solid reliability. Built on the trusted Tokyo Marui Hi-Capa 4.3 platform and finished in a bold orange/black motif, this pistol pairs proven Marui internals with a curated parts list of high-quality CNC aluminum, performance springs, and competition ergonomics. The result is a pistol that looks extreme on the range and behaves even better under pressure.

Designed for competitive shooters and serious skirmish players, the Arena King combines lightweight aluminum components for crisp controls and positive feedback (frame, trigger, ambi safeties, slide, magwell, and hammer pad) with a tuned recoil/hammer spring kit, reinforced nozzle springs, and a proven recoil buffer to smooth follow-ups and protect internals during sustained rapid fire. A bright fiber optic front sight, integrated RMR-ready footprint, and included AEX RMR red dot make target acquisition instant — perfect for speed drills and CQB stages.

Every Arena King receives professional installation and bench-tuning by AEX techs: barrel fitment, slide/frame mating, trigger geometry check, and a final function test to ensure the package runs reliably right out of the box. If you want competition performance wrapped in aggressive styling, this build earns its name on the chrono and the leaderboard.
