Small and compact, it adds less than 1.5 in \/ 36 mm to the overall length. Precision-machined from 6061 aircraft-grade aluminum, it weighs only 2 oz, delivering maximum performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCO₂ Configuration:\u003c\/strong\u003e\u003cbr\u003eWhen used with \u003cstrong\u003eCO₂\u003c\/strong\u003e, the expansion ring is installed. CO₂ is stored as a liquid under pressure, and when the valve opens, liquid CO₂ can rush directly toward the launcher’s valve. The 12 internal chambers provide additional space and dwell time for the CO₂ to expand from liquid into gas before reaching the valve. This stabilizes pressure, reduces cold shock, and minimizes velocity drop, valve freeze, and O-ring damage, helping maximize usable CO₂ pressure for consistent, peak performance.\u003cbr\u003e\u003cstrong\u003eFeatures:\u003cbr\u003e\u003c\/strong\u003e- Uses the 12-chamber expansion ring\u003cbr\u003e- Allows liquid CO₂ to expand into gas before reaching the valve\u003cbr\u003e- Stabilizes pressure and reduces cold shock\u003cbr\u003e- Minimizes velocity drop, valve freeze, and O-ring damage\u003cbr\u003e- Maximizes usable CO₂ pressure for peak launcher performance\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHPA Configuration\u003c\/strong\u003e:\u003cbr\u003eWhen used with \u003cstrong\u003eHPA\u003c\/strong\u003e, the expansion ring is removed and the unit functions as an HPA volumizer.
