● Hop-up adjustments at the Top Dead Center (TDC) without removing the slide.
● Adds 14mm CCW threading at the muzzle.
● Made from lightweight, high-precision CNC-machined aluminum.
CNC aluminum outer barrel compatible with the Tokyo Marui Hi-CAPA 5.1 gas blowback pistol. Allows hop-up adjustments from the screw located on the top without disassembling the slide. Hop-up pressure is applied from the top center of the chamber, providing more stable hop-up performance compared to conventional hop-up units. The combination of a rigid aluminum alloy construction and a non-tilting design enables more consistent and accurate shots. The muzzle features 14mm CCW threading, compatible with various muzzle accessories. The mounting method has been improved to minimize outer barrel misalignment.
