Marksman Carbine

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

Characteristics
The Marksman carbine is a semi-automatic, medium-power rifle with a 20-round magazine. Mounted with an enhanced-zoom scope that shares the same reticle as the anti-materiel rifle and sniper rifle, it is highly accurate and deadly at long range with a guns skill of 100. With its good damage, an extremely high rate of fire and a good sized magazine, it can deal a large amount of damage-per-second, making it versatile and useful weapon against most enemies.

Behind the Scenes
According to J.E. Sawyer the Marksman Rifle is loosely based around "paratrooper-oriented marksman rifles" and are present due to New Vegas' Proximity to Nellis AFB.
