thats a pretty big drop! ummm i'd say your best bet is getting a spring change. you can try a crawler barrel i just dont if it'd drop your fps that much

lol, trevor, mabey you should fully read and understand the platform that he is asking about before you start giving out tech advice.
that might work for the common aeg, but as he is asking about the king arms "GAS BLOW BACK" rifle, he will need to take different steps.

what you need is an n-pas valve avalible from ra-tech. here is a video from ra-tech demonstrating its use.
