How many rounds can magazines of the M16 hold?

The M16 rifle is typically equipped with magazines that hold 20 or 30 rounds of ammunition. The 20-round magazine was standard for earlier models, while the 30-round magazine has become more common in later versions of the M16 and the related M4 carbine.

The capacity of 30 rounds is significant as it allows for sustained fire without the need for frequent reloading during engagements. This capacity, along with the rifle’s design for semi-automatic and automatic fire modes, makes it an effective weapon for infantry use.

While there are larger capacity magazines available for the M16 platform, such as extended magazines that may hold 40 or more rounds, the standard issue magazines for the M16 are primarily the 20- and 30-round options. Therefore, the choice indicating 20 to 30 rounds accurately reflects the standard capacities used for M16 magazines.
