Decent grip with qualifications - FAB Defense Ergonomic Folding Pistol Grip for M16/M4/AR15

This grip is perfect for the fact that I can store my scoped MSR in a more compact space, and that's what I was after. There is a little bit of "play" left to right in the grip when it is fully locked into Open. But no more than the play between an upper receiver and lower. However, if you want a rock-solid grip option, this may not be for you.
