Dispelling lubrication and cleaning myths
SWAT Magazine published a reprint of Pat Rogers great article on carbine cleaning and lubrication drills back in 2016, see link above and scroll down to the section headed "Cleaning Regime That What Works for Me".
The article talks about his experience of a 3 day cleaning regime in the Marine Corps (MCRD) and the section above moves to a ten minute regime that he adopted later in life.
