Mirroring bones when rigging valve skeleton in 3dsmax?

[Crossu88]

So I've embarked upon a daring journey to rig insurgency's characters into player models and NPCs. The only thing I want to know is whether or not it's possible to mirror bone positions without having to manually do the math for it. I'm using 3dsmax and it would help speed up a lot of my projects if I was just able to mirror the positions of the arms and finger bones to match the other side of the body. Any advice is appreciated. Thanks for those that take the time to give any so.

try the mirror modifier

Mirror them from the bone tools option and not the mirror modifier.
