Cow Cow B01 Dynamic Blowback Housing - Silver

The Cow Cow B01 Dynamic Blowback Housing in Silver is a precision CNC‑machined aluminum upgrade for Tokyo Marui Hi‑CAPA and 1911 series gas blowback pistols, built to enhance reliability and gas efficiency without adding bulk. Designed for players who demand consistent cycling and durable construction, it delivers a noticeable upgrade in performance and feel.

• Material: Aluminium 7075, CNC machined for rigid, durable construction that resists flexing under hard use.
• Weight: Ultra‑light at 18 grams to preserve balance and cycling response.
• Finish: Silver alloy with strong corrosion resistance; available also in Black for different builds.
• Compatibility: Specifically designed for Tokyo Marui Hi‑CAPA and 1911 series GBB pistols.
• Performance: Improves blowback cycling and gas transmission for smoother operation and reliable cycling under load.
• Piston Head Design: Special piston head geometry keeps the O‑ring in optimal condition, reducing leaks during action.
• O‑Ring Versatility: Includes multiple anti‑oil O‑ring sizes to fit commonly used nozzles in the market, easing installation across variants.
• Anti‑Wobble: Engineered to minimize wobble during nozzle movement for a steadier, more consistent seal.
• Installation Considerations: The piston screw ships loosened; tighten during installation. Use a drop of screw glue and allow overnight curing to prevent thread damage. Note that fitting requires intermediate knowledge or a gunsmith; refer to a qualified professional for proper installation and fitment.
• Maintenance: Regular maintenance is recommended to keep the blowback system in peak condition and reduce wear on moving parts.

The B01 Blowback Housing is a purpose‑built upgrade for serious airsoft enthusiasts who value consistent gas efficiency and reliable blowback performance. By combining a lightweight yet durable aluminum body with precision tolerances and adaptable O‑ring sizing, it helps minimize leakage, stabilize cycling, and extend the life of your pistol’s internals. Remember to follow the installation and curing guidance to ensure a secure, long‑lasting fit, and schedule routine maintenance to keep your setup performing at its best.
