M4A1

The M4A1 (stylized as gun_m4a1) is an assault rifle test weapon. It has a high rate of fire and a reload mechanism. The M4A1 takes the standard number 2 assault rifle slot. It does not have visible bullets by default, though the bullet impacts can be observed.

The M4A1 has an incredible fire rate and is the fastest weapon in the game. It also maintains a surprisingly good accuracy and can fire an almost straight stream of bullets. Its projectiles have the power of a standard rifle. This is one of the experimental weapons, like the Glock.

The M4A1's magazine contains 30 rounds, which can be unloaded in about two seconds. The weapon fires 15 shots per second, which is roughly the same as its real-life counterpart. Occasionally, the weapon will glitch and only fire a single shot before having to reload. If the player tries to fire in bursts or 'semi-automatic' the M4A1's capacity will likely be reduced to 16 rounds until the next reload.

Trivia

 * A way to make the bullets visible is use the 'debug' cheat.
 * Firing it in 'semi-automatic' is difficult, because its high rate of fire typically yields 2 or 3 bullets per click.
 * It is based on the M4A1 Carbine.
 * It is excellent for flying.
 * The Glock was found a day after someone first discovered this gun.
 * This gun has been around since the beginning of the game, as a test weapon. However, the weapon first appeared in customs maps on June 9, 2012.
 * This gun is frowned upon by the developer and can't be found in approved maps. This may be because it is not a fair weapon to fight with, due to its damage and fire rate.
 * When the player reloads the weapon, the magazine seems to disappear then reappear.
