Service Rifle

The Service Rifle is a weapon

Gameplay
A semi-automatic rifle that uses 5.56mm ammunition and has a magazine capacity of 20 rounds. The weapon is used by NCR troopers.

The rifle can be used to repair weapons such as the light machine gun, sniper rifle and assault carbine using the Jury Rigging perk. The Service Rifle can be modified with a forged receiver to increase durability and an upgraded spring to increase the rate of fire.

Durability
The Service Rifle can fire a total of about 1,995 standard rounds, the equivalent of 100 reloads, from full condition before breaking. When modified with the forged receiver, it can fire a total of about 2,995 standard rounds, the equivalent of 150 reloads, from full condition before breaking.

Behind the scenes
Josh Sawyer commented that the Service Rifles are pre-War, a "sorta" mish-mash of an AR-15 and AR-10.

Bugs

 * Sometimes in V.A.T.S., the rifle will disappear from the player character's hands; the animation will continue, however, which will waste ammunition, and do no damage to the enemy. The gun will reappear when the V.A.T.S. animation ends. This glitch may happen outside V.A.T.S. as well, when crouching, but can be fixed by simply standing up.
 * When completing the aid for Camp Guardian a loop can be created through dialogue with Private Halford to obtain one rifle, 15 armor piercing 5.56mm rounds and 32 5.56mm rounds by going through the top dialogue options repeatedly.
 * When upgraded with both the upgraded springs and the forged receiver, shooting with surplus ammunition makes the Condition jump to 100% before it starts to decline. The condition drops to a certain point around the 75% mark on the scale and then jumps to 100% Condition making 5.56mm surplus ammunition much more valuable as a repair exploit. The process is repeatable.
