M16A1

Summary
The M16A1 was developed to cater to the problems the original M16 had during the SANI Virus's first outbreak phase. It was given a larger magazine size and more reliable parts making it jam a lot less.

Tips

 * This weapon can kill Normal Zombies with three body shots.
 * Switch to semi firing mode to conserve ammunition when engaging normal zombies.
 * Try to aim for headshots when using burst firing mode, as you'll be doing 270 damage with it; enough to kill a Ticker in two bursts.
 * Semi firing mode is more accurate than burst.
 * Engaging a Brute with this weapon at medium to far range is encouraged due to its high DPS, and a surprising amount of accuracy.
 * It's highly recommended to equip Bulldozer I when using this weapon, as in heated situations you'll burn through ammunition quickly. The extra clips could very well save you.
 * It is recommended for the user to space out burst in order to prevent overheating, resulting in better accuracy than spam.
 * Bursting while ADS requires vertical compensation.
 * If you have a quick trigger finger, turn it to semi, crouch, and ADS for the best results.
 * It is best to use burst mode on hordes of zombies, as you can wipe out most of the zombies, if you have the ammo.
