those c02 bottles are very expensive at 7.50 for an 88 gram bottle which you only get 100 full power shots from and about 200 before it is finished.
So i decided to get a 20oz (560 gram) paintball bottle and a remote line to connect to the rifle,i also needed a paintball to 88 gram C02 thread adaptor which i searched on the net for,i found 2 places to get them norway and the USA and both were out of stock and wanted 28 for it plus postage. This morning i purchased the paintball tank and the remote line ,the line came with a quick release fitting and a foster nipple,i got my mig welder out and cut the threads off the nipple and welded it to the back of an empty C02 cartridge and using the hole in the nipple as a guide drilled a hole through the rear of the cartridge .Next i drilled out the puncture hole at the front of the cartridge to aid gas flow, then blew all the swarf out with an airline and then ran a full can of brake cleaner through the cartridge to clean the insides.
I screwed the modified empty cartridge to my rifle i had to cut a small hole in the front of the stock to pass the remote line through and connect it to the foster nipple on the back of the modified C02 cartridge, then i opened the valve on the paintball bottle and the gun was charged with C02.so i saved about 30 for the adaptor
I will make the next empty cartridge with a one way nipple so i can refill the cartridge and disconnect the quick release from the nipple to remove the line and paintball bottle, this mod will save me loadsa money.In my garage i have a 5 kilo C02 fire extinguisher all i need to connect that to the paintball tank is a foster nipple and i will be able to refill my paintball tank using the fire extinguisher :) it only costs 2 to fill the fire extinguisher with 5 kilos of C02 which will fill about 8 paintball bottles or 56 cartridges which i reckon will be at least 5600 full power shots or in other words 56 times 88 gram cartridges to buy at 7.50 each would come to 420.
