I think Drill Sargent Preston wore dirty white gloves when he inspected our M-16A1’s. Nobody ever passed an inspection…
Once every six months. The other five I only field stripe clean.
Yes in the military it is clen or dirty one spec of dirt/residue and it is dirty.
His gloves may have been dirty, but I bet your weapon was spotless!
Hell, NONE of my firearms will ever pass that inspection, because they get shot, a lot!!!
So a follow up shot as an example.
One of my classes was 3 days 3-500 rounds of ammo expended on drills every day. The firearm of choice? Glock 48 MOS.
Some would think that the gun needs to be detail striped, cleaned and lubed every day to assure 100% reliability and quite frankly such a regiment is more dangerous than helpful.
My routine is during the day during breaks I add a drop or two of Mobile 1 to the inside of the slide into the rails and wipe the external areas where the black gushy stuff is seeping out with a rag.
At night, steal one of the hand towels the hotel nicely provides and use it as my “oily rag” usually soaked with CLP to wipe down all visible fouling I can reach during a simple field strip. I do NOT mess with the bore at all. I then spread a thin coat of grease into the rails and re-assemble. Then a room service cheeseburger and study next day drills and get the rest of my gear ready. The magazines just get a simple exterior wipe down and get reloaded.
I can guarantee the gun will not pass a white glove test, hell it’ll take two weeks to get all the black stuff scrubbed out of the skin in my hands. BUT it will run at 100%, minimally disturbed with unnecessary mechanical maintenance.
I prefer my firearms appropriately lubricated, so I guess I would fail this guy’s inspection.
I agree proper lubrication is key to the best performance and delivering you load without failure …
Who are the dudes in the orange shirts?
Monks?
Do you know how often you can fire a clean firearm?
Once!
I clean my firearms after every shooting session, but nowhere near the way I cleaned them in the Army.
I trade mine in on new ones when they get dirty, like a Mercedes owner with a flat tire. 
I don’t believe you let go of any of 'em… 
Probably. I’m anal and clean after every range trip.
No way in hell.
