Like new pre-ban Colt 20inch chrome lined heavy barrel thats threaded with a flash hider. Sorry no bayo-lug as this came off a transition gun. This is a complete barrel assembly including barrel nut, delta ring, gas tube, and handguards. All parts are Colt factory. I am asking $210 delivered. Also I have a nice Fabian DTA mil-brake I can have permanently attached if you need a post-ban barrel. This will cost about $50 more. Please contact me by e-mail, thanks Chris.
