Gen3 Folding Stock Adapter for AR style pistols and rifles. Alloy construction, same as all the other alloy folding adapters, just not as expensive. Has a built in quick disconnect on the bottom for sling attachment so you can use standard end plate. Installation instructions are included. On a 1 to 10 scale, the install is about 5. Just need to be able to read and a castle nut wrench. Allen wrenches are included. Please be careful not to lose the rear pin spring that is behind the end plate, the spring is small and likes to eject itself if you are not careful.
