Apex walks us through the upgrade of a Tokyo Marui Hi-Capa GBB Pistol using Nexxspeed parts. He unboxes and prepares to install a fresh CNC aluminum blowback unit (BBU), a matching aluminum nozzle, and a 180% nozzle spring. The aluminum construction is highlighted as a durable fix for a component that shouldn't break, though the installation gets off to a slightly chaotic start when the presenter realizes the parts are thirsty for some much-needed lubrication.
