AEX Custom MIDORI SOUR — Tokyo Marui Hi-Capa 5.1 Gas Blowback Pistol — Custom Hi-Capa (5.1 Platform)

The AEX Custom MIDORI SOUR is a clean, crisp, competition-ready Hi-Capa build that blends premium lightweight components with a vibrant silver-and-green aesthetic. Built on the ultra-reliable Tokyo Marui Hi-Capa 5.1 platform, this custom pistol is engineered for fast cycling, improved shot consistency, and excellent ergonomics for competitive players, speedsofters, and fans of high-performance sidearms. Dominating in both looks and handling, this build represents that perfect balance of style and function.

The MIDORI SOUR features a full suite of CNC aluminum upgrades, including the Dr Black Type 850 slide, a spiral-fluted green Dr Black outer barrel, an AIP aluminum trigger, and an AIP CNC hammer pad — all designed to reduce reciprocating mass, sharpen up the recoil impulse, and enhance overall reliability. A stippled AIP grip set improves stability and recoil control, while the EDGE Type 3 magwell in silver ensures lightning-fast reloads. The build is powered by a 140% enhanced recoil/hammer spring set to give the slide extra snap and maintain consistent cycling even with rapid firing.

Every AEX custom pistol is professionally assembled, fitted, and test-fired by our in-house technicians. We verify slide/frame alignment, trigger feel, gas efficiency, and barrel fitment to ensure the MIDORI SOUR runs flawlessly right out of the box. If you want a high-output custom Hi-Capa with a stylish colorway and serious competitive performance, this build was made for you.
