Primary cause of mg stoppages is failure to extract,then failure to feed. M2 50 cal is known to heat up and rip the rim off the cartridge case, bolt goes back case gets rim ripped away and fails to extract. Next cartridge is already removed from link and gets shoved into hole from previous casing stuck in chamber. Now fails to feed,you can try to recharge but not gonna work since rimless brass can't be extracted. Will need ruptured casing tool and remove barell to fix.
M2 fires from a closed not open bolt.
