The M107 is a sniper rifle available in DayZ. Designed to take down light armor, the gun is absolutely devastating to infantry even at range, since its massive .50BMG (12.7x99mm NATO, the same as the AS50) round makes for 1 hit kills against players. However, due to limitations in ArmA2, it is impossible to take down multiple targets with one bullet.
With two levels of zoom and a scope zeroable up to 1200m, this gun is still in many ways inferior to its counterpart, the AS50. It lacks range, accuracy and can only use 10Rnd. M107. However, the M107 is more common than its counterpart, spawning in the barracks at the northwest airfield, while the AS50 spawns only at helicopter crashes. But, like the AS50, the M107 cannot be used with NV Goggles.
This weapon can be heard by zombies in nearly a half kilometer radius, making it inadvisable to use for killing them, as it will only attract more.

Because of this, you can drop dead out of nowhere, never hearing the sniper's bullet before you die.
The weapon's scope reticle can also serve as an improvised rangefinder to estimate the distance to the target.As of 18.104.22.168, The M107 and AS50 are no longer available in-game. Their damage values have been set to 0 to prevent anyone with hacking capabilities from spawning either back in.
