Aero Enhanced Buffer Tube w Castle Nut and Endplate (pre-owned)

Pre-owned in good condition. Aero Enhanced buffer tube with castle nut and standard endplate. The buffer tube and parts are in newish condition, but the previous person who installed them was a little rough with them. The castle nut notches have been rolled over a little. The groove in threads of the tube are in good shape, but you can see where the tube was not secured. The customer brought this in for me to replace with new parts. I didn't charge him for the work, and am selling this for what that would have cost. All parts are functional. End plate has not been staked.
