This complete air unit from WE Tech, also known as Blowback Unit (BBU) or cylinder/nozzle housing, is an original (OEM) replacement part designed specifically for Gas Blowback (GBB) pistols in the Hi-Capa 5.1 and higher series (e.g., 6"), both WE and other brands compatible with the same standard.
This unit is the "engine" of the blowback system housed inside the slide. A worn or damaged BBU is a primary cause of malfunctions, power loss, and irregular cycling. Replacing the entire unit with this original WE part ensures perfect compatibility and restoration of "out-of-the-box" performance.
The kit is complete and includes:
- The main housing.
- The piston, which is an integral part of the structure.
- The original rubber piston head for optimal sealing.
- The steel springs for the nozzle return.

- Compatibility: GBB Hi-Capa 5.1, 6" and higher pistols (WE and compatible clones)
