Hi everyone, I have a JG AUG A4 and I would like to reduce the power from 401 fps(at last chrono) to 330-350fps. After doing some reading ive found a change of spring is the best way to do this. Ive read an ASG Ultimate M100 spring would give around 330-350fps which is perfect however im unsure if that spring is compatible with my AUG.
So my questions are :-
1) Are all spring compatible with all AEG's?
2) If not is the M100 spring compatible with my JG A4 AUG?
Thanks for any help
