Like new original Colt M16A2 20inch barrel assembly complete with delta ring, gas tube, and handguards. The barrel is chrome lined, has a 1x7 twist, and is threaded with bayo-lug. This Colt barrel assembly has had less than 100 rounds put thru it and overall still looks almost like new. I am asking *Sold*. Pics will be available to a serious buyer. Please contact me via e-mail.
