12.7mm Submachine Gun

The  is a weapon in Fallout: New Vegas.

Characteristics
More common in higher levels, the is a heavy duty large caliber submachine gun (SMG). It features a unique top mounted magazine, which lies parallel to the weapon's barrel, much like the P90c. It boasts a high damage-per-second, but suffers from a small magazine capacity and an fairly large spread, however this spread is less than that of the 10mm SMG (as of patch 1.3.0.452). It is also one of only two 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 other being the silenced .22 SMG.

Unlike other submachine guns, the is classified as a two-handed weapon; because of this, traveling with the weapon unholstered will slow the player character's movement speed. This also causes the weapon to be holstered on the back, rather than on the hip as with other SMGs. This also affects it with regard to the jury rigging perk, putting it in the same repair class as the service rifle and light machine gun, instead of with one-handed automatics like the 10mm SMG and 9mm SMG.

The 12.7mm SMG is exactly as durable as the weaker 10mm SMG; it can fire 2500 standard rounds, or about 119 magazines before breaking.

Modification

Locations

 * Bloodborne cave - behind a very hard locked gate in a box along with just under 8000 caps. There is a key to the gate lying by the campfire in the back of the cave (be wary of the tripwire behind the gate).
 * Hidden Valley Bunker - can be bought from Knight Torres.
 * The Fort - can be obtained from Legion soldiers.
 * Commonly found on Legion Vexillarius at higher levels.
 * At higher levels, this can be bought from various weapon merchants. It is most commonly sold by Gun Runners.
 * Great Khans have been observed having the weapon on them in relatively low condition at higher levels.
 * In the Honest Hearts add-on, it is used often by the White Legs at higher levels.

Behind the scenes

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