Eugene Stoner designed the weapon to fire a small grain, fast burning powder. The DOD substituted a large grain, slow burning powder that they had warehouses full of. With the replacement powder it was still burning when it reached the gas port, hence the action jamming. A second but still dangerous fault was the orginial three prong flash suppressor which tended to bend and become non-usable.
Lyonheart Both the Lewis and the Maxim have their good points. The Lewis was air-cooled but the Maxim could and was sized up to fire 37mm cannon shells (the 2pdr pom pom)
M-16. I never had a problem with mine in SEA. My older brother was a marine stationed at Khe Sanh. His unit came to the conclusion it was incompatible manufacturing of the feed cartridges and magazines. His gunny refused certain manufacturers once they figured out the serial number ID (like a VIN).
