Hi all I’m new to this forum and gbbs. Recently got the TM MP7a1 gbb and I love it! Only problem I’m having is filling the mag with gas. I’ve followed others posts about holding the mag upside down (valve pointing up) and making sure the valve and can are in line properly. When I fill it I get a lot of the liquid squirting out and not much goes into the mag ( I don’t get my shots off) I’m using WE green gas.
anyone else had problems? What am I doing wrong?
thanks
