The assault carbine is a weapon in Fallout: New Vegas.


Assault carbine expanded

The assault carbine is a magazine-fed, compact automatic weapon with a high rate of fire and a comparatively low spread. It is one of the most accurate automatic weapons in the game and can be effectively used in close and medium range combat. In V.A.T.S. mode, it will shoot a 5 round burst for a cost of 20 Action Points.

The assault carbine uses 5mm rounds, boasting an armor piercing effect of -10 DT, and 5mm AP rounds, which have a -25 DT effect. These make the weapon highly effective against medium armored or heavily armored targets, as only power armor possesses more than 25 DT. In addition, 5mm HP rounds have only a x2 DT multiplier, compared to the x3 multiplier of other HP rounds (all effects as of patch The 5mm ammunition is available in large quantities, but the assault carbine suffers from a low base damage of 13, the second lowest of any rifle in the game.

The assault carbine can be equipped with an extended magazine, identical to that used on the regular marksman carbine except with a black rather than aluminum finish.


The assault carbine can fire a total of about 3,745 standard rounds, the equivalent of 157 reloads, or 125 reloads when modified with extended magazines, from full condition before breaking.

  • When experiencing a malfunction with the assault carbine (or any other weapons which share its reload animation) the Courier will utilize the forward assist to fully seat the bolt carrier group.
  • It has a similar look to the service rifle, although it has a shorter barrel, ergonomic handgrips, matte black furniture and a collapsible stock instead of a fixed wooden one.

Behind the scenes

According to J.E. Sawyer, the marksman and assault carbines are present "in part due to New Vegas' proximity to Nellis AFB."[Non-canon 1][Non-canon 2]

  1. Question: "Is the Marksman Carbine loosely based on the POF Short Barreled Rifle?"
    J.E. Sawyer: "No. It's loosely based on some paratrooper-oriented marksman rifles I saw online. It and the Assault Carbine are present in part due to New Vegas' proximity to Nellis AFB."
    (J.E. Sawyer on Formspring)
  2. Question: "FO3 establishes that the R91 Assault Rifle was the standard issue armament for the National Guard. Why then is it not included in FNV? I understand the lack of Chinese ARs, but it seems like the R91 would have been a better fit than the assault carbine."
    J.E. Sawyer: "The Assault Carbine is not standard issue. They are intended to be paratrooper weapons, which is why Boomers have so many of them."
