M16

 "For when the trees start growling" - CoStar6 

Description
The 'M16' or the 'Armalite Rifle Model 16' is a tried and true American Assault Rifle. It was made during the Vietnam war to replace the M14. Currently, the US military uses a successor of it called the M4 (not the M4A1, which is an entirely separate gun), although some soldiers still use it.

This weapon has a good Fire Rate, and deals decent damage. The M16 has an amazing accuracy so don't worry about hitting enemies from Long ranges

Survivors

 * This is a recommended purchase, it has good damage, firerate and accuracy
 * The ammo, however, is low when compared to other automatics, but it doesn't really matter
 * Use the accuracy to its full potential
 * Attack Tanglers and Hunters from mid-long range, this could help your team

Zombies

 * Due to the accuracy, you might take damage in the process
 * Use a zombie that can take the damage well if you plan on going close and personal
 * Riots are good for this, due to the forcefield and huge charging damage
 * If the map is small, you don't have to worry about the accuracy, so it'll be easier at getting closer
 * However it does 22 damage, so you'll still die pretty fast if you use a weak zombie
