HPA buffer tubes

HPA buffer tubes are a key component of the rear structure of an HPA airsoft replica. They allow the installation of HPA-compatible stocks and help manage air line routing.

What is an HPA buffer tube?

Unlike standard AEG buffer tubes, HPA buffer tubes are designed to fit high pressure air systems, ensuring stability and compatibility with HPA stocks.

Types of HPA buffer tubes

  • Standard AR buffer tubes – M4 / AR15 / MTW compatibility
  • Reinforced buffer tubes – increased durability
  • HPA-specific tubes – optimized air line routing
  • Mil-spec threaded tubes

Compatibility

Our HPA buffer tubes are compatible with major airsoft HPA platforms including MTW, M4 and AR-based replicas using PolarStar, Wolverine, GATE or Mancraft systems.
