The M16 rifle, officially designated Rifle, Caliber 5.56 mm, M16, is a United States military adaptation of the Armalite AR-15 rifle.In 1964, the M16 entered American military service and the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the U.S. military's standard service rifle. The M16A1 improvements include a bolt-assist, chrome plated bore and a new 30-round magazine.The U.S. Army XM16E1 was essentially the same weapon as the M16 with the addition of a forward assist and corresponding notches in the bolt carrier. The M16A1 was the finalized production model in 1967. To address issues raised by the XM16E1's testing cycle, a closed, bird-cage flash suppressor replaced the XM16E1's three-pronged flash suppressor which caught on twigs and leaves. Various other changes were made after numerous problems in the field. Cleaning kits were developed and issued while barrels with chrome-plated chambers and later fully lined bores were introduced. With these and other changes, the malfunction rate slowly declined and new soldiers were generally unfamiliar with early problems. A rib was built into the side of the receiver on the XM16E1 to help prevent accidentally pressing the magazine release button while closing the ejection port cover. This rib was later extended on production M16A1s to help in preventing the magazine release from inadvertently being pressed. The hole in the bolt that accepts the cam pin was crimped inward on one side, in such a way that the cam pin may not be inserted with the bolt installed backwards, which would cause failures to eject until corrected. The M16A1 is no longer in service with the United States, but is still standard issue in many world armies.

|Introduction||为了取代不擅长丛林作战的M14，我踏上了本国有史以来最为黑暗的战场。虽然立下了一些战功，但是也出了很多状况。好在最后基本都解决了，还随之衍生出了不少新型号。有几个妹妹总不是坏事吧，算是因祸得福呢。||To replace the M14 poorly suited for jungle warfare, I embarked into the darkest battlefield my nation has ever faced. My service has been remarkable, but it wasn't without problems. Good thing is that my issues were all eventually resolved, and many new models resulted from that.
