This not correct. Moly is greatly superior to Teflon. Moly will continue to lubricate even after the grease is nearly gone, as it forms a tenacious layer on the underlying metal. It's only drawback is it is dark-colored. The film it leaves still lubricates although it is thin. "Thin" boundary lubrication is fine if it works, and it will, bearing loads beyond anything Teflon can do. As a chemistry professor, I have examined this issue carefully.
I am concerned that the grease you mention which contains the moly is too thick for your firearms applications. Maybe, maybe not. Cold weather might affect functioning.
PTFE or Teflon is okay in cleaners like BreakFree but not particularly of value for superior, durable lubrication. When it is used, the carrier oil or grease is as important as the Teflon. I have yet to see it give superior, long-lasting lubrication the way moly does. I use both and know which I clearly prefer.
You could try one of the DuPont lubes which you can find at various places, like hardware stores or on Amazon, Teflon is DuPont's own product, and they make good product.
A VERY good, very cheap answer is to use a good quality Mercon ATF such as by Valvoline or Mobil, as a gun lube and protectant. Synthetic is best. I like Mobil 1 brand ATF. Or Valvoline Maxlife. Cheap, and it cleans well. It is a great lube, and penetrates well; it is physically and to a degree, chemically similar to sperm whale oil, long considered the very best lubricant oil for fine guns. If it isn't thick enough, follow gunsmith Grant Cunningham's advice and thicken the ATF with some STP oil additive. It will then stay in place on auto gun rails.
Power Steering fluid as sold by Valvoline is similar or identical to ATF, but without he red dye if the dye is staining clothes.
I imagine you can mix in a little of the moly grease, as well, but it might not work. Experiment.
To use ATF as a truly superior cleaner, Google "Ed's Red" on the Internet ( skip.the acetone and lanolin if you want).
Be cautious about lubing the lugs on bolts! This can be dangerous.
