Get some rounds thru the barrel and use frog lube. It will keep your bolt carrier group nice and juicy and repel dirt, debris and carbon. Good luck
The forward assist and dust cover are there for a reason. We used both in the USMC. They are good to have if needed. The Sports don't have them because they are cheaper to manufactuer and an entry level AR.
