XPR-50（游戏文件中称作AS50）是使命召唤：黑色行动2、使命召唤：突击队和使命召唤：黑色行动3中的一把狙击步枪。
使命召唤：黑色行动2[]
- “半自动狙击步枪，命中胸部及其以上部位是致命的，有着中等的后坐力。”
- ——“创建作战配置”中的描述
战役[]
XPR-50在完成关卡“与我受难”后解锁，出现在关卡“奥德修斯”中供玩家提供狙击支援来完成一个挑战，此外是关卡“审判日”中的默认武器之一。
多人对战[]
XPR-50是多人对战中最后解锁的狙击步枪，于52级解锁。
XPR-50是一把伤害中等的狙击步枪，能造成95的基础伤害，没有伤害衰减，计算伤害加成后命中手臂、躯干上部及其以上部位能一击致命，但装配消音器后命中手臂前端不再能一击致命，且命中腹部的伤害会降低到90。XPR-50有着高穿透力，其子弹射穿掩体后依然有着较高的伤害，但造成一击致命的概率会大大降低。
XPR-50的射速高于狙击枪的平均水平，射速限制是375发/分钟，开火速度超过这个数值的话会限制开火。此外，XPR-50有着媲美Ballista的伤害，使它有着可观的输出。
XPR-50的后坐力较高，瞄准时准星晃动的幅度在狙击枪中排名第二，只比DSR-50的小。XPR-50在站立时的准星回正速度很低，数值上只有725，不过在下蹲或匍匐时其数值会提高，下蹲时为942，匍匐时则大幅升高至1160。
XPR-50的部分性能相对较差，有着较高的瞄准时间，为400毫秒，同时像其它狙击枪一样有着极差的腰射准度，使得腰射几乎无法击中敌人，换弹速度也较低，战术换弹需要3.5秒，完全换弹则需要4.1秒，但换弹到2.45秒时便可取消多余换弹动作。
XPR-50的弹匣容量为8发，每次重生时都有三个后备弹匣，加起来玩家一开始就有32发子弹，通过拾取弹药，最多可以拥有64发后备弹药，即8个弹匣。在狙击步枪中，XPR-50的弹药量仅比SVU-AS少，而实际上后者消耗弹药的速度更快，仅靠XPR-50的初始弹药，玩家也可以获得可观的击杀数。
XPR-50的可选配件同其它狙击步枪基本一样。消音器可以让玩家开火时不暴露在敌方的小地图上，但是会失去击中手臂一枪致死的能力，但XPR-50是半自动武器，并非特别依赖单发射击来杀敌，而且击中胸部时仍然是致命的，因此消音器仍是个值得考虑的配件。
弹道计算器能降低30%的武器瞄准晃动，降低幅度相当可观，与变倍瞄准镜搭配使用可以进一步降低瞄准晃动。
The Variable Zoom Scope gives the XPR-50 two zoom levels, one less zoom than the standard scope, the other with more zoom than the standard scope. This scope can help the user spot targets from further away, or have an easier time tracking targets up close. The Dual Band Scope creates a thermal overlay that will highlight enemies not using Cold-Blooded as bright orange, while Cold Blooded users are unaffected and do not have their color changed. The ACOG Scope grants view of the mini-map, peripheral vision, and a low zoom level relative to the XPR-50's other sight pictures. The ACOG Scope also doesn't restrict the user's ability to hold breath, but the prompt to do so will not appear on screen.
Fast Mag decreases the XPR-50's reload time, reducing the speeds to 2.36 seconds for a partially filled magazine, 2.56 seconds for an empty magazine, and a 1.45 second reload cancel speed. This reload speed is one of the fastest in its class. Extended Clip will increase the reload time by ten percent, but will increase the magazine capacity to eleven rounds, roughly a 38% increase, while increasing the starting ammo loadout to 44 rounds, and a maximum of 88 rounds between the gun and reserve magazines.
The Laser Sight will reduce the hip-fire spread significantly, while giving a protruding laser. It's mostly the latter effect that is most valuable on sniper rifles, since players who tend to quickscope may find that the Laser Sight gives a visual aid of where to aim.
FMJ will increase the XPR-50's penetration power even further. The XPR-50 will be able to tear through most pieces of cover without major repercussions, if not completely unhindered by the obstacle(s), as only the un-penetrable obstacles will stop the user completely. Considering the XPR-50 already has excellent penetration, however, FMJ is considered an overkill attachment that only helps in very specific scenarios.

使命召唤：突击队[]
The XPR-50 appears in Call of Duty: Strike Team. It is unlocked after buying the "Stealth Package" Care Package, which contains the perk "Sniper", which increases Sniper Rifle Damage, three Claymores, and the XPR-50. In addition, the XPR-50 is given by default a suppressor for silent kills.
使命召唤：黑色行动3[]
- “半自动点50口径狙击步枪，命中胸部及其以上位置能一击杀敌。在举枪瞄准时长按左摇杆/L3/Shift屏住呼吸。”
- ——“创建作战配置”中的描述
XPR-50在使命召唤：黑色行动3中于2018年3月6日回归，仅能通过空投补给获取，其造型与黑色行动2中的原版武器几乎无异。
The XPR-50 is a versatile sniper rifle, as it can kill in one shot to the chest with the ability to pull off follow-up shots because of its semi-automatic nature. However, while the recoil's kick is only moderate, it resets quite slowly, so being patient with subsequent shots is advised. The default scope is quite clear with a T-shaped reticle, which is adequate for long-range engagements, but optics with lower zoom are helpful for close and medium ranges.
The handling properties are average compared to other sniper rifles. Hipfire accuracy is poor, although rapid fire without aiming can be used as a last resort when caught off-guard in close quarters. Idle sway is moderate, so Ballistics CPU is helpful when using the default scope in making sure the first bullet hits the one-shot kill area. With a magazine size of eight and a fairly slow reload, coupled with the potentially rapid use of bullets, Fast Mags or Extended Mags are recommended. Suppressor is a decent choice, as it incurs no penalty to sniper rifles, and masks the very loud firing sound the XPR-50 emits.
