Hi guys - recently DROS-ed my first AR. It will be a Stag lower mated to an Armalite 20" upper. A true A2-style AR rifle, which is kind of what I wanted for my first AR.
I'm not new to rifles, nor even semi-auto ones, but as stated this will be my first AR. Any tips for cleaning and maintenance that i should know? I can't tell whether the upper is a piston or not. The person I bought it from said he hadn't fired it, but said (while peeking through the holes in the handguards) that it was a piston upper. However, upon field stripping and removing the BCG and charging handle, the tube that protrudes into the action appears to be just that - a tube, which would suggest a DGI. Wouldn't the thing that sticks into the action be a solid rod if it were a piston?
In either case, it doesn't matter to me. I'd be just as happy with either DGI or a piston, but, if it were a DGI, what should I do to clean it/maintain it?
