Can anyone point me in the right direction in terms of what springs are being used for AICS bottom metals?

Length, rate, diameter, etc.
 
On the AI AICS?

On AICS pattern bottom metals. I'm working on one and don't really know what spring to put in one. I'm using the spring from a clicky pen right now for testing purposes, but I need something sturdier for actual use.
 
From my limited experiences the typical latch spring is similar to the trigger spring or hammer spring in an AR-15. I think I have a picture of one out of an AICS. If I find it I'll post it.
