I recently purchased a JMac Customs folding stock with the Sig Sauer folding mechanism. I cannot figure out how to make the mechanism fold/unfold. Any help?
It’s hard to do not attached to the firearm. At the hinge joint put your thumb on the top with your hand around the stock like a golf club. Use your thumb to push down and the stock will raise up, then you can fold it over.
I don't have a JMac but it looks like it operates like my Sig folder. Have you tried it mounted on the weapon, it may just be tight and you need the extra leverage?
