Hello everybody, so I started paintball about 6 years ago and play a few times a year. But in the last few games, ive got a taste for blood and want to make my own custom gun! I can do basic metal and a lot of woodwork but before i get into all that (which I'd like to get to by the end of the year) I'd like to know what im getting into before I just jump right in.

1st: Those HPA tanks with the buttstocks on them, can a standard co2 tank just screw into where the hpa tank goes therefore making the co2 tank the buttstock.

2nd: Is there any sort of barrel extention or really long barrel like a 25-30", perferably for an a-5

Thanks everybody for putting up with my pathetic questions and what not. More will probably be on the way

I didn't find the right solution from the Internet.
