HAO

HAO supplies CNC components and conversion kits for Marui MWS and Systema PTW airsoft platforms. The catalogue includes upper receivers, bolt-carrier components and build kits associated with profiles such as HK416, M4/AR15 and M27. MWS gas-blowback parts and PTW components belong to different internal systems and must be selected by platform, not by external appearance alone.

Receivers, carriers and conversion assemblies each occupy a different part of the build. A receiver set determines mounting points and external dimensions, while a bolt-carrier component belongs to the cycling system of the stated platform. HAO kits may combine several related parts, so the contents and the required donor replica should be checked before comparing them with an individual component.

When selecting a HAO product, confirm MWS or PTW compatibility, the exact model or kit version and every stated thread, interface and dimension. Muzzle-device threads, hop-up arrangements and receiver fittings can vary between platforms and generations. Use the individual product specification as the fitment reference rather than assuming that parts for two similar replica profiles are interchangeable.
