Built from lightweight aluminum and fitted with an industry-standard repeater pin valve, the bottle balances portability with ample capacity—typically delivering roughly 800–1,000 shots per fill depending on marker setup, environmental conditions, and firing cadence. The cylinder carries a fresh date stamp (manufacture date) and meets DOT and TC certifications; it requires hydrostatic re-testing every five years to remain compliant.\u003c\/p\u003e\n\n\u003ch3\u003eHow much shooting time will this 20 oz tank provide?\u003c\/h3\u003e\n\u003cp\u003eShot count varies by marker type, shot rate, and ambient temperature. In everyday recreational play with a standard CO2 marker, expect approximately 800–1,000 shots per full 20 oz fill; aggressive firing or mechanical inefficiencies will reduce that number.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTypical range: ~800–1,000 shots per fill for common markers\u003c\/li\u003e\n  \u003cli\u003eCold weather reduces effective shots per fill\u003c\/li\u003e\n  \u003cli\u003eHigh-rate firing and leaks shorten runtime\u003c\/li\u003e\n  \u003cli\u003eMarker tuning and efficiency improve shot count\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this tank ready to use out of the box?\u003c\/h3\u003e\n\u003cp\u003eNo—this Maddog tank ships empty to comply with transport rules.
