B02 Dynamic Blowback Housing | Piston Head Version | CowCow

B02 Dynamic Blowback Housing | Piston Head Version | CowCow – for your replica

This blowback housing is a crucial internal component for your GBBR pistol. It enables the blowback action by converting gas pressure into mechanical force. You replace it when your current blowback housing is worn out or when you want to improve cycle speed and gas efficiency. A good blowback housing is important for consistent performance during skirms.

Technical specifications

This blowback housing is CNC machined from 7075 aluminium for maximum strength. With a weight of only 18 grams, this component ensures a faster blowback cycle. The material prevents deformation under gas pressure. The housing is available in black and silver, with the colour being purely an aesthetic choice.

Compatibility and application

This blowback housing is specifically designed for Tokyo Marui Hi-Capa and 1911 Series GBBR pistols. Please note: the piston head is not included – this fits standard TM piston heads and COWCOW piston head CCT-TMHC-054. Installation requires disassembly of your slide and replacement of the complete blowback unit. This is an upgrade for advanced technicians familiar with GBBR internals.
