Key Features

  • Fixes Barrel Wobble – Reinforced body and integrated barrel nut greatly reduce or eliminate barrel play on VFC HK416A5 GBB platforms.

  • Drop-In Compatibility – Slightly enlarged chamber bore (CB) accepts OEM and most aftermarket hop-up units—e.g., GHK chamber—without fitting or modification. No promise to accept all aftermarket parts.

  • Self-Centering Design – Internal CB taper auto-centers the inner barrel; the integrated barrel nut maintains alignment under load.

  • CNC Precision – Tight, repeatable tolerances for consistent assembly and accuracy.

Compatibility

  • Fits all VFC AR-15 / M4 / HK416 GBB models (including HK416A5).

  • Direct upgrade/replacement for VFC part VG20ADC040.

Notes

  • Hardcoat aluminum offers the best weight-to-wear performance; stainless provides maximum robustness at higher mass.

  • As with any coated/treated part, avoid metal-on-metal scraping during installation; light lubricant on threads and bearing faces is recommended.

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.
