STAINLESS STEEL • SILVER-TONED APPEARANCE • INTERNAL 11MM CW THREAD • TOKYO MARUI-SPEC HI-CAPA 4.3 DESIGN
Give your compatible Hi-CAPA 4.3 a metallic accent with the 5KU Stainless Steel Threaded Outer Barrel – Stainless. This replacement component combines stainless steel construction, internal muzzle threading and a decorative .45 ACP chamber marking.
Designed for compatible Tokyo Marui-spec Hi-CAPA 4.3 gas blowback airsoft pistols, the Stainless version offers a silver-toned alternative to black or gold configurations. Confirm fitment with your exact pistol before ordering.
STAINLESS STEEL CONSTRUCTION
The outer barrel is manufactured from stainless steel, providing a metal replacement option for a compatible factory component.
Its metallic appearance creates contrast against darker slides and frames. It can also complement other silver-toned components in a coordinated Hi-CAPA build.
Surface condition depends on handling, maintenance and contact with surrounding moving parts.
DESIGNED FOR HI-CAPA 4.3
This version is designed around the Tokyo Marui-spec Hi-CAPA 4.3 platform. Select it according to your pistol’s exact model, production version and component requirements.
Hi-CAPA-style pistols from different manufacturers can have different dimensions and tolerances. Fitment is not guaranteed across every brand, aftermarket slide or barrel assembly.
Compatibility with the longer Hi-CAPA 5.1 configuration should not be assumed.
INTERNAL 11MM CLOCKWISE THREADING
The muzzle features internal 11mm clockwise threading, also described as 11mm CW or positive.
The threads sit inside the muzzle opening, maintaining a clean exterior profile. Check thread diameter, direction and clearance when selecting a compatible airsoft accessory.
11mm CW and 11mm CCW are different interfaces. A matching thread specification alone does not establish complete accessory compatibility.
DECORATIVE .45 ACP CHAMBER MARKING
A .45 ACP chamber marking adds an exterior detail to the stainless appearance.
The marking is decorative. This product is an airsoft outer barrel for compatible 6mm gas blowback replicas.
