This upgraded chamber base is CNC–machined from durable T6 aluminum with hard anodizing & black nitrite steel and engineered for a precise, tight fit within the VFC MCX APFG GBB platform. Its reinforced structure and optimized thread geometry deliver a major durability boost—especially when pairing the system with heavier steel outer barrels.

Key Highlights

  • Direct compatibility with the 4UANTUM Magnus Pro AR TDC Hop-Up Chamber (VFC/GHK AR/M4 GBB)
    The Magnus Pro chamber installs directly into this chamber base with no modification required. Adjust your hop-up exactly as before via the fake ejection port—clean, intuitive, and functional.
  • Invisible internal upgrade for maximum realism
    Once installed, the chamber base is completely hidden. You can remove the OEM external hop-up adjustment rod entirely, giving your MCX build a far more authentic appearance.
  • Ready for steel outer barrels (separately available)
    The redesigned front section features significantly strengthened material (steel) to support heavy steel outer barrels with no flex or risk of stripping.

Product Characteristics & Cosmetic Standards

Our products are manufactured using precision machining and industrial finishing processes. As a result, minor cosmetic characteristics may be present, including but not limited to light machining marks, tool traces, finish variations, minor surface marks, slight discoloration, or light surface oxidation where applicable.

In mechanical systems, slight movement, wobble, or play between components may occur due to designed tolerances and does not affect function or performance.

These characteristics are purely cosmetic or tolerance-related, fall within normal manufacturing standards of the airsoft industry, and do not constitute a product defect.

Returns or warranty claims based solely on such cosmetic or tolerance-related characteristics may therefore be declined in accordance with our return policy.

Light surface oxidation (rust), where applicable, is a normal material property and can typically be removed through routine maintenance (e.g., WD-40 and a soft brush).

This notice does not limit any statutory consumer rights.
