CO2 tanks are made from high quality aluminum that's light but tough! A 12 oz tank fill will get you about 500-700 shots. All tanks have an industry standard pin valve that will fit any standard ASA. The pin valve uses a standard #10 o-ring (included) which costs pennies to replace. Tanks are shipped empty to comply with safety standards. Can be filled at fields or sporting good stores just about anywhere!

Attention Canadian customers: This tank does have a TC stamp!
