When the Marine Corps was first issued the M-16 in Vietnam {1967} a product called “Dry Slide” was provided for lubrication. It looked like dissolved graphite but I think it was silicone based. It tended to cake up when exposed to heat and cause malfunctions. It was replaced by another product—gun oil.

Dri-Slide contains Molybdenum Disulphide which is a great lubricant especially in high heat, high pressure situations.

I use it on my guns and airguns. I remember my Daisy Powerline airguns say to use 30 weight non-detergent motor oil for both lubrication and protection.

I have often wondered how well synthetic motor oil would do for gun oil. It is really cheap compared to the name brands. I know it is expensive for motor oil but in motor oil quantities it is pretty cheap per ounce.

Not disagreeing with y’all, understand, but wasn’t the malfunction issue found to be carbonates from the caustic wash Winchester used to neutralize the acids used in manufacture of the propellent?
