Master Class
Oil, it’s what I was trained to use on the M-16A1 back in basic and during unit armorer training. Bolt Carrier and bolt, very light coat on other metal to metal surfaces (e.g. upper & lower contact) occasionally super light and springs and other metal to prevent corrosion.
As far as brand I generally use Hoppe’s lubricating gun oil.
