Have been on the hunt for quite sometime looking for a titan defense td-415 upper. I absolutely love hk-416's and 416 clones but not willing to pay the $2500-$5k price tag for a 416 upper. I know there are some titan defense uppers still out there; recently saw a 14.5 and 16in sale for decent prices on GunBroker but I need a 10.5 in. Anyone who could point me in the right direction or who has one they are willing to part with at a reasonable price would be much appreciated.
