[Hectic]

Jesus. I dont think ive ever emptied a hicap that fast lmao.
Pull tue trigger for a seccond or two and have to rewind.
On semi the cycle is done befor you even let off the trigger and the fastest tap i can do on auto results in a 3 round burst.
And because its an mp5sd with such a light spring light piston and sorbo that mofo is quiet. Even damn quiet on dry fire but with bbs damn. This should be quite the cqb machine.
Thanks all for the input. Gonna grab a lonex shell next week as i wasnt 100% satisfied with the results of shimming on this cyma box but overall it turned out well.
One more thing. Piston head. Aluminium or polycarb?
