Max Power 12 Expansion Chamber For CO2 And HPA Volumizer

The Max Power 12‑Chamber Expansion Chamber is precision‑machined from 6061 aircraft‑grade aluminum for durability and lightweight performance. Weighing only 2 oz, it adds less than 1.5 in (36 mm) to overall length, keeping your launcher compact. In CO₂ mode the twelve chambers give liquid CO₂ space to expand into gas before reaching the valve, stabilizing pressure and reducing cold shock. This design minimizes velocity drop, valve freeze, and O‑ring wear for consistent peak performance. When the expansion ring is removed, the unit functions as an HPA volumizer, storing extra air volume to prevent pressure depletion between shots. The adapter body provides reliable airflow for each firing cycle, maintaining power and accuracy. It is compatible with a wide range of platforms including paintball markers, airsoft guns, BB and pellet guns, and defense launchers. The modular two‑piece construction allows easy conversion between CO₂ and HPA configurations. Engineered for rugged field use, it enhances reliability without adding bulk.
