Rifle length is preferable if your going to use a suppressor. I have an 18 Faxon Group Buy barrel with mid length gas with carbine buffer and spring. My 18 barrel is not over gassed and a good shooter with a non adjustable gas block. You definitely want an adjustable gas block if your going to use a suppressor. My Faxon has the proper size gas port but Satern/Liberty 18 barrels are known for having large gas ports and being over gassed.
