This folding mechanism surpassed my expectations. The skeleton stock is badass. My Zastava looks mean as hell.
Sig 1913 folding mechanism.
Locks up tight as advertised, recommend.
The folding mech is incredible. Extremely smooth and perfect for its uses. If it’s in stock, buy one, as they sell extremely fast
Installed this on my Zastava m92 pistol. It’s easy to install at the perfect height. I also like that it is reversible so I can decide whether I want it to fold right or left. Along with the Ab-8r arm bar and tailhook, my pistol is so much more functional.
If your thinking about getting this SIG MECH, don’t think twice about it just get it, you won’t regret it.!!! :)
Great product.... a little stiff at first but does loosen up .
Absolutely perfect! Solid folding mech for my Galil Ace with zero play.
Not a lot to comment on - it's a folding mechanism. But it is a rock solid folding mechanism, and super compact at the same time. No push buttons to lock or unlock, simply position your hand slightly behind the hinge and lift slightly while pushing your thumb down into the receiver side and it will lift out of the locking catch and swing to the left smoothly. It stays folded, but with a quick pull it will snap open and lock into place fast. JMac is the only place I've seen these knuckles available for sale individually - a great resource for builders looking to develop their own skeletonized braces or stocks.
