Controversy erupted immediately and continued for years. Reports from Vietnam of jamming led to questions of reliability. Investigation proved jams resulted from not cleaning the rifle, and that it was not a self‐cleaning weapon as manufacturers claimed. Some complaints indicated that the small 5.56‐caliber 55‐grain bullet lacked adequate impact. Conversely, others charged the ultrafast munition caused inhumane internal damage to its victims. Soldiers eventually adapted to the M‐16 and accepted its capabilities along with its shortcomings.
In the 1990s, the model M‐16A2 was still the standard small arm for the United States. The 7.78‐pound rifle is equipped with a 30‐round magazine and fires a 62‐grain bullet with an effective range of 550 meters.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
