Thanks everybody.

I measured the fps and rof with an xcortech chrony. As for my boss' CA M15A4, I believe you're right when you say it came up graded from the factory. What I know is that he certainly didn't upgrade it, and just got it in the mail from airsoft atlanta a couple of days ago.

My understanding of batteries is that the voltage mainly affects ROF, and amperage the battery life. For the record, it's a 9.6V nunchuck at 1950 mAh. Of course I'm open to suggestions on either a) a new battery, or b) a completely different type of battery.

I have tried playing with the motor height, and I see no improvement. I will open the thing to see if someone shimmed it like a doof.

It is fitted with a systema tightbore and a metal hopup, which I have adjusted.

Does anyone have a feel for what gearset belongs in this thing?
