COWCOW B02 Blowback Housing (Piston Head Ver.) for TM Hi-Capa & 1911 GBB Pistols

The COWCOW B02 blowback housing is a purpose-built upgrade for TM Hi-Capa and 1911 gas blowback pistols. Designed for enthusiasts and competition shooters, it delivers more consistent cycling and reduces frame flex for steadier performance.

• Material: CNC-machined 7075 aluminum for a rigid, lightweight housing that resists flexing and warping under gas pressure.
• Weight: Ultra-light at 18 g, preserving firearm balance and handling cues while enhancing reliability.
• Compatibility: Fits TM Hi-Capa and 1911 GBB pistols and is compatible with stock TM piston head or COWCOW Piston head for flexible setup.
• Gas Transmission: Optimized geometry improves gas flow and pressure transfer to the slide, leading to steadier cycling.
• Performance Design: Precision CNC finish and tight tolerances ensure precise fit and smooth operation within the frame recesses.
• Durability: Hardened aluminum construction helps resist wear from repeated gas cycling, extending part life.

The B02 housing minimizes frame flex during firing, delivering a more predictable recoil impulse and easier follow-up shots. It’s ideal for players upgrading stock components, those using aftermarket pistons, or anyone seeking a stable, repeatable action from each shot. When paired with the appropriate piston head, this part can enhance gas efficiency and cycling stability, contributing to tighter groups and more consistent performance in rapid-fire or prolonged sessions.
