Lightest folding hinge! - Samson Picatinny Side Folding Rifle Stock Adapter

This is the lightest 1913 folding hinge on the market. It's also very well designed. Other hinges, such as SIG or JMAC, require leverage to fold but, this hinge has an easy-to-use button. The others aren't difficult to fold once you break them in and get the hang of it but, in my opinion, this design is superior. The tension screw is also easy to adjust so even though the folder doesn't lock when folded, it will stay folded as long as the screw is applying enough tension. You can adjust it to your desired tension. I've now purchased 3 of these for JMAC SS stocks.
