Regular and fully modified
The assault carbine is a magazine-fed, compact automatic weapon with a high rate of fire and a comparatively low spread, created specifically for use by American paratroopers. It is one of the most accurate automatic weapons in the game, and can be effectively used in close and long range combat.
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 18.104.22.1682). 5mm ammunition is available in large quantities, as it is also used by the high-capacity minigun. In V.A.T.S mode, it will shoot a 5 round burst for a cost of 20 action points.
A fully repaired assault carbine can fire 3747 rounds before breaking.
