AEX Custom Sovereign Blue Tokyo Marui Hi Capa 5.1 Gas Blowback Pistol (Blue / Silver)

The AEX Custom “Sovereign Blue” is a refined, competition-inspired Hi-Capa build based on the precision-engineered Tokyo Marui Hi-Capa 5.1 platform. Designed to balance smooth performance with a striking blue-and-silver colorway, this custom sidearm delivers fast cycling, reliable operation, and elegant visual presence on and off the field.

At the core of the build is the Gunsmith Bros LimCat WildCat aluminum slide in blue, offering reduced weight for faster recoil recovery and a bold competition aesthetic. Paired with the COWCOW OB1 stainless-steel threaded outer barrel, the Sovereign Blue provides excellent rigidity, consistent cycling, and compatibility with tracer units or suppressor-style accessories.

Finished with premium aluminum controls including a short-stroke trigger and low-profile magwell, this Hi-Capa is tuned for shooters who value precision, speed, and refined design. The Sovereign Blue is a statement build — clean, confident, and unmistakably AEX.
