I think I'm going to stick with the Automag for a while. It needs a little tweaking and probably the level 10 upgrade, but overall, I think it can be a really nice gun. If I hit the sweet spot on the trigger, I can easily get it up to 13-14 bps.
It was a hit at the field, too. Everybody thought it looked cool and wanted to hold it. One guy asked if I wanted to sell it, haha.
I don't know why people complain about the weight so much. The tank is the majority of the weight anyway (and yes, I got a carbon fiber tank, not steel), and it's not like my arms felt tired after running around on the field with it.
