basically i just bought the mg7 online and got it the other day.
shot a few paintballs out of it(cant find a hopper for it, so just stuck one in and shot)
but today i went to put in a brand newly filled 20z CO2 tank, and it shot like i had nothing in it, and the guage on it just made it to what i expect to be the 100 psi mark.
any ideas why and how i can fix it?
also if you have any links where i can buy upgrades for it would be great.
