Good, solid stock - FAB Defense M4 Folding, Collapsible Buttstock for Milled AK

This is a very good, well made, solid stock and bolts on tightly for a milled receiver. The folding mechanism is crisp and tight. The hex bolt behind the folding mechanism attaches to a wing nut inside the receiver. The hex bolt arrived so tight that I thought it was permanently fixed. I did figure it out, though, and was able to snug everything down holding the wing nut inside the receiver, while tightening the hex bolt behind. Very satisfied.
