K2

The K2 is an Assault Rifle. The K2 is a very accurate rifle, making it a great anti-sniper weapon. It was the first (and only) AR that had no automatic fire, but instead had both burst and semi-automatic modes.

The K2 has received a full-auto setting in the 10-16-08 Patch, increasing the popularity of this gun since it is now the only weapon that can fire in all 3 modes.

Although it is one of the better assault weapons out there, it has been underused because of the "easier" weapons. However, since it's one of the lower-ranked weapons, most new-ish players use this unique rifle alongside the M4A1, retaining a bit of its popularity.

Trivia

 * The K2 has been called the "M4A1 of the Post-September Era".
 * The SCAR-L and the K2 have very similar statistics, being equals in power, portability, and accuracy. The K2 however, has a slightly faster rate of fire, and offers a semi automatic firing mode, and has a lower Rank Restriction. However, the SCAR seems to be more prevalent. One possible reason the SCAR-L is used more often is because the K2's recoil pattern is rather strange and awkward to get used to.
