|quotetext=N/AThe M4A1 is a carbine version of the [[M16A2]], equipped with a 14.5 inch barrel, a retractable stock, and most importantly, a full-auto mode instead of a burst mode. Small, light, deadly, customizable, and enduringly popular, the M4A1 is in fact the most popular combat rifle of the Mazes, and it is a staple of any sensible armory or personal collection. If you don't have one already, get one! And if you have one already, then get another!|quoteauthor=N/ATempest
