Spring force/coefficient of a bullet button?

[cwiz]

Anyone know the spring force of the spring in a bullet button build kit? spring coefficient would be perfect but whatever you have...

I guess you can calculate it (F=kx). You can use something for a known weight and then measure how much the spring displaces using a caliper or something. The more accurate the measurements, the more accurate your result will be. I guess this will get you close.

ya ya ya, i just don't have the equipment to measure force accurately.
