Most CO2 bottles (18-24 oz.) on the market will work for the NightWatch as long as they have a brass fitting (not galvanized). It's also important to purchase a CO2 bottle that has a stem level with the top of the valve. Brands of CO2 bottles that are compatible with the NightWatch include the Rhino Power (sold at most Lowes), Guerilla and PMI. Any paintball store will be able to sell you a filled bottle as well.
Due to federal regulations we are unable to ship a filled CO2 bottle in the mail, but we can ship a fully compatible empty bottle. The bottle may be taken to any paint ball store or CO2 refill station to be filled for between $1-$5 normally. The bottle is refillable and may be used over and over.
