  — Item Description 

The M16A4 Firebug is an assault rifle released during the 07/18/13 unscheduled game update.


The M16A4 Firebug is a NX Standard, smooth-bore variant in the M16 family of assault rifles.

Comparing to the GP-Standard version, the M16A4, the stat changes are as follows: one point damage buff, an increase of eight points in portability, a point increase in rate of fire, a point increase in accuracy and a decrease of one point in recoil.

These stats are comparable to the widely used M416 CQB. The Firebug has a one point increase in damage, a seven point increase in accuracy, one point advantage in rate of fire, but a one point decrease in portability and one point more recoil. Additionally, the Firebug does not come with a pre-attached sight.

The Firebug's most noticeable improvement over the original M16A4 is that it is much more portable. The drawback to the M16A4 was its portability, which is near the lower end of the AR spectrum. Now that it has been counteracted, players can confidently move around with the Firebug without fear of being too slow to get to choke points quicker or run from enemies faster.
