In my experience the US military overcleans rifles to a stupid degree. It was not uncommon to see steel dental picks brought out to scrap carbon out of the chamber of an M4. This was a "life hack" sometimes taught by SNCOs. People cared more about having a spotless rifle (because arms room retards also demanded it) than not scraping the shit out of the inside of their rifle.
I've gone to ranges where I had my rifle perfectly cleaned and oiled just right when some SNCO dingus with a squirt bottle full of oil would force people to open their bolts while they absolutely hosed the inside with oil.

>NGSW stuff
Yup. The NGSW was pushed by people who saw an opportunity to misrepresent how engagements worked, and by using Afghanistan cherrypick data about intermediate cartridges being less successful at the extreme ranges of the very particular environment in certain situations. This had already been solved by the DMR program (and I think DMRs should be standard in TO&E at the platoon level just to solve this small gap but anyway) and at engagements inside extreme ranges the 5.56mm worked fine. But industry shills preyed on the outlier data and the fuddlore addled brains of the people in command to get the NGSW spun up. Once Afghanistan died down and extreme range was no longer on everyone's mind, the NGSW justification changed to fear mongering about Chinese body armor. We are dealing with dinosaurs in institutions who still think 5.56mm was a mistake.
