M4A1

Background Story
US and NATO service rifle chambered in .223 Remington or 5.56 x 45mm NATO based on Eugene Stoner's Iconic AR15 and AR10 designs. It does less damage than the AKM or the Kalashnikova but it has a faster cyclic rate and is favored with better accuracy, range, and velocity.

However, its higher price tag and heavy ammo consumption leaves it to be desired, and it shares some traits with the AK47, which leads to the ongoing debate (even in the midst of an apocalypse, people still find something to argue about) about which gun is better.

Tips

 * Firing slowly will maintain good accuracy.

Trivia

 * This weapon is manufactured by Leftover Brains.
 * Despite being much more modern than a Kalashnikov, it still falls behind in some aspects.
