Exact 13.7 inch format for the Marui MWS platform
The Angry Gun K-OBS13.7-MWS outer barrel set is made for the Tokyo Marui MWS GBB series. It combines a black KAC style appearance with a stated outer barrel length of 13.7 inches. This exact product code separates it from the shorter 11.5 inch set available within the same Angry Gun range.
Thirteen point seven inches converts to approximately 34.8 cm. The measurement applies to the outer barrel specified for this product and should not be treated as a confirmed inner barrel or handguard measurement.
Three coordinated external components
Angry Gun describes an aluminium outer barrel and aluminium gas block together with a stainless steel dummy gas tube. These details establish a multi-part set rather than a bare outer barrel supplied on its own. Each component should be identified by its individual material when the product specifications are entered.
Functional and dummy parts distinguished
The stainless steel tube recreates the visible gas-tube detail associated with the KAC style layout. It is explicitly a dummy component and does not carry the propellant gas used by the MWS replica. The gas block and outer barrel are both aluminium components with a black exterior finish.
Tokyo Marui MWS series compatibility
The manufacturer states compatibility with the Marui MWS GBB series. That confirmation should not be expanded to AEG receivers, WA-pattern systems or other brands of gas rifle without separate dimensional verification. Similar AR or M4 styling does not guarantee a shared outer barrel interface.
Plan the surrounding parts separately
Before ordering, confirm that the host replica uses the Tokyo Marui MWS system and that a 13.7 inch outer barrel suits the intended configuration. The inner barrel, hop-up assembly, handguard and muzzle device are not identified as included with this set. Their lengths and interfaces must be checked independently.

Identify the correct barrel length
The K-OBS13.7-MWS code is specific to this 13.7 inch edition. It should not be confused with the 11.5 inch version, which has a different overall length and product reference. Using the complete code is particularly useful when matching the set with other MWS external components.
Installation considerations
Outer barrel replacement requires partial upper-assembly disassembly and correct alignment of the fitted components. Use workshop tools suited to the MWS system. Professional installation is recommended when the user is unfamiliar with this platform.
