- Weapon description

Campaign
In the single player campaign, the XP-100R is sometimes seen used by the American Militia. The most common way the players obtain them is by taking them off a dead member of the militia. the XP-100R has a small internal magazine (holding four rounds), is the fastest bolt-action in the game, can be drawn as fast as any other pistol, and usually kills enemies with one shot even at long range. However, the pistol's small magazine capacity, and low rate of fire could put the player at a disadvantage during close range engagements.

It can be found with a Sniper scope or Acog scope attachment.

Multiplayer
The XP-100R in mulitplayer has similar stats to its campaign counterpart. The most notable difference is that the XP-100R does 70 damgage in multiplayer instead of 100. The XP-100R deals the highest damage per round out of all the pistols.

Available attachments for the pistol include a sniper scope, acog scope, tactical knife, and silencer. It is the only pistol in the game that can be attached with a sniper scope, but the only one that doesn't have an extended magazine attachment.
