"I was @ 23 rps with my E&L AKS74N
13 to 1, hi comp piston yadda yadda yadda
Using a stock E&L motor.
Put in the ASG 40k......30 rps.
I have a perun v3 and it was very snappy, now it is somehow snappier.

I have a Reaper HPA build.
This AEG competes tit for tat with my HPA build.
Do this motor, spend that dollar.
Be that guy.

"I put this motor in my King Arms PDW and paired it with 16:1 SHS gears and 11.1v battery. Massive upgrade to trigger response and RPS.
