B&T Air APC9SD² Silencer Extension (GBB)

The B&T Air APC9SD² Silencer Extension is designed for the APC9K SD² platform and is compatible with GBB, AEG, and HPA variants. It attaches to the factory silencer assembly to increase overall length, creating the full SD² configuration while maintaining factory fitment and alignment.

Full SD² Configuration

This extension module increases the overall length of the APC9SD² silencer assembly. It is designed to complete the full SD²-style profile while preserving the factory look and fit.

Replacement or Upgrade Component

Originally included with select APC9K SD² GBB models, this part is offered as a replacement or upgrade component. It allows users of the AEG / HPA models to add the second silencer stage to their APC9K SD² setups using a factory-aligned external module.

Airsoft Performance Utility

For airsoft use, the extended internal volume can help accommodate longer inner barrels or house compatible tracer units and other internal accessories. This gives users more flexibility while keeping the original SD²-style exterior configuration.
