More common at higher levels, the 12.7mm submachine gun is a heavy-duty large caliber submachine gun (SMG). It features an unconventional top-mounted magazine, which lies parallel to the weapon's barrel. It boasts a high damage-per-second, but suffers from a small magazine capacity and a fairly large spread, though this spread is still less than that of the 10mm SMG (as of patch It is also one of only three fully automatic weapons which are capable of being silenced, (the silencer is not to be confused with the 12.7mm pistol silencer, as they are not interchangeable), the others being the silenced .22 SMG and Sleepytyme (GRA).

This weapon has more weapon modifications available to it than the standard version.


The 12.7mm submachine gun (GRA) can fire a total of about 2,495 standard rounds, the equivalent of 119 reloads, or 93 reloads when modified with stacked magazines, from full condition before breaking.

  • Like the anti-materiel rifle's suppressor, the 12.7mm SMG's suppressor only reduces the weapon's noise from loud to normal, rather than completely silencing it, meaning that NPCs will still hear the shots, albeit not as easily as before.
  • The GRA version of the silencer (suppressor) on this weapon is not interchangable with the one for the standard version silencer.

Behind the scenesEdit

The 12.7mm SMG is almost entirely fictional, though a couple of elements were loosely inspired by the FN P90 and TDI Vector.[1]
