USMC M240 disassembly and assembly

Took 3 hours but the FN M249 got its first real deep cleaning and is spotless! There were tons of brass shavings inside likely due to the scraping that occurs as rounds are pushed out of the belt links, crazy! Being piston-driven it’s somewhat easier to clean vs a DI AR but the sheer number of rounds we put through it was the issue. But now this has to be the cleanest M249 that has ever existed in all of history, so let’s run a few belts through it to ruin that… 👊🏻🤘🏻 #m249 #beltfed #556 #fnh
