Sig 556 folding stock?

[Ed.]

Does anyone know how to reverse the measures taken to make the folding stock on the Sig 556 CA compliant?

That depends on how it was pinned. One way is to remove both roll pins and put a spacer inside the spring. If that is the case, you can just remove the spacer. Some people use a setscrew, so you would need to find that and remove it.

That set screw would be at the top of the button housing as visible with the stock removed by knocking out the hinge pin and removing the stock from the rifle? When I remove the stock as stated above I cannot remove the button.
