Free floating keymod rail *

The rail is a cheap free floating rail that full disclosure, floats away. Encountered issues with poor design that rail doesn't lock to barrel nut. Gun is worth much more but whoever gets it will most likely need a new rail so I'm asking $500 OBO, I am willing to take a hit on this and will entertain reasonable offers. I am a handgun guy and don't have the energy to deal with it. I am located in Phoenix, more specifically Scottsdale.
