Worth every Penny
I originally ordered the MP7 with a short Barrel. The Energy output was lackluster with 1.3 Joules for .4g BBs and 150PSI. Powair6 Support was verry quick to help me. In the Timespan of only a week they rebuild the MP7 with a 280mm Barrel. Now it easily reaches 2 Joules at 150PSI, anmd shoots laser Beams. All in all great customer support. An expensive airsoft yes, but worth every Penny
