"Doomsday" Hi-Capa Prebuild

"Doomsday" Custom Hi-Capa Prebuild Airsoft Pistol – Green & Gold

Stand out with the Doomsday Custom Hi-Capa, a Tokyo Marui 5.1-based gas blowback airsoft pistol pairing a striking green-and-gold colorway with an extensive selection of performance upgrades.

The green Dr. Black Type 800 slide features angular cutouts that showcase the gold LA Capa Hex Cut outer barrel beneath. A matching green LA Capa S1 aluminum grip carries the colorway through the lower half, while gold controls, a Hive hammer, and a Defender magwell complete the look. The black frame adds contrast, giving the bright finishes a bold, defined appearance.

Internally, the build focuses on cycling, air seal, and shot consistency. The Dr. Black blowback unit pairs with an LA Capa Turbo Nozzle Full Set, designed to support consistent gas delivery and dependable cycling. The PDI 113mm inner barrel, TTI brass one-piece hop-up unit, and LA Capa Flat Hop bucking form an upgraded barrel and hop-up assembly focused on accuracy and consistency.

A Waldo 140% recoil spring and AIP 140% nozzle spring provide increased spring tension for slide and nozzle return. The CowCow trigger and upgraded firing components round out the internal package, while AIP front and rear fiber-optic sights provide a clear aiming reference. A textured aluminum grip and flared Defender magwell support controlled handling and magazine changes.

With coordinated styling and upgrades throughout, Doomsday brings a distinctive finish to a performance-focused custom Hi-Capa build.
