One rifle is a Colt 6450 (9MM) LEO stamped lower receiver about 500 rounds no marks or nicks at all. Second ar is a RRA 14.5 flattop. Steve w/ADCO put the upper together for me. I am looking for a New to LNIB DSA Congo Type rifle with folding stock or Paratrooper style.. Please email me for more details. Thanks for looking.
