I've got an AAP01 solely to keep me in the game if my main gets hit, as site rules dictate.
What I would like to know is there 1 single upgrade to increase the fps,I know it's bad out of the box and I'll only be running on .2 bb's.
Thanks .
I never find the FPS is an issue on my AAP - low 300s if i remember right. Certainly seems not far short of the range of a reasonably shooting AEG. I seem to recall that the WE glock mags give you a slight FPS boost over the standard AAP mags. But if you have a load of the latter already, you could try experimenting with retrofitting a WE glock mag valve to the AAP mag? e.g. https://www.bullseyecountrysport.co.uk/we-magazine-exhaust-valve-g17-gas-10277-p.asp
