scuba tanks

hey does anyone no where you can buy a used scuba tank to fill my gun off of? everywere i have tried only has expensive new ones and i just cant afford that right now
Thanks

a place on calgary trail south around 70 Ave has used ones for about $200

youd need a very large scuba tank to fill your tank multiple times....

and you'll need to get a fill station for the tank which will run you about $100

I bought a new tank (aluminum) at ocean sports for $200. And you should get 2 of them for any good fills.

Pm me, i'll tell you were to look.
