I'm contemplating assembling another AR. This time i'm going for a 16" mid length dissipator. I never seen one and i like the concept. I don't like the shorty handguards on a 16" and i don't want to get a free floating full length hand guard either. I bought a Bizarre Czech/Canadian stripped lower,dpms lower parts kit, Stag a3 upper, magpul folder(going green this time). My major setback is I can't source a 16" dissipator barrel anywhere where i live. My one and only option is to chop a down 20" heavy barrel to spec or start from a blank. Any thoughts from those who have a dissipator?
