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 mil-dot reticle as the anti-materiel rifle and sniper rifle, but its barrel and magazine appear to have a stainless steel coating, it is highly accurate and deadly at long range with a Guns skill of 100. Additionally, it has a very low Action Point cost of 14, lower than most pistols as well as being the lowest out of any rifle in the game.

Durability
The marksman carbine can fire a total of about 1995 standard rounds, the equivalent of 100 reloads, from full condition before breaking.

Behind the scenes
According to J.E. Sawyer, the marksman carbine is loosely based around "paratrooper-oriented marksman rifles" and are present due to New Vegas' proximity to Nellis AFB.
