I have been thinking more about 'run it wet'. Ran a new carbine and had FTE within a few rounds (started dry, on purpose, 'cause I never had, and wanted to solve a failure). Then lubed the whole thing copiously - entire BCG, carrier, inside of upper, chamber, heck, probably even the dust door. No more FTE's, but all that isn't necessary, yeah? Where does one really need lots o'lube, and where is less alright? I don't want unnecessary oil to attract dirt to the areas that don't need it, and if I can avoid any more spray in the face through the charging handle, that's always a plus (without paying $90+ for a gasbuster CH).
