This is a 14.5 barrel by Centurion Arms set up perfectly for an AEMS5 suppressor (if youre in Mass they do make a faux suppressor to complete the look) it comes with a Aimpoint 5000 red dot with a surefire 660 and tape switch. It does come with BCG and CH. Email me if interested 

PS **********they dont have Centurion Arms in the drop menu below so I just picked Colt cause I had to pick something**********
