How to Play

This loadout for M16 is a solid pick for medium to large-scale maps and game modes, like Ground War and Invasion, because of its overall range and accuracy. The M16 also excels in capture-and-hold game modes such as Domination and Hardpoint where enemies will be grouped up in particular locations.

Having Double Time, Fast Hands, and Battle Rage on this loadout allow players to become more agile and make up for the slow mobility of the M16 weapon.

All weapon attachments here help the M16 to become more accurate and deadly at mid to long-range shootouts. It is recommended for players to anchor objective areas in the map as the burst fire mode can find high value in areas with multiple targets.
