Single Player[]
The Ranger is most found in the level "The Hornet's Nest". To the Militia it is the most used shotgun, along with the Model 1887. They are sometimes used Akimbo, although this is very rare. It's always found Akimbo in Museum.
Multiplayer[]
The Ranger is unlocked at Level 42. The gun is unique in that its sights cannot be aimed down. Instead, the ADS-button fires the second barrel, similar to firing weapons with Akimbo. With the Akimbo attachment, the aim down sights button fires one shotgun while the fire button fires the other. Pressing the button again fires the second barrel of the respective shotgun. Thus, at most, Ranger users can only fire two barrels at a time. Akimbo is one of the more preferable attachments as it gives the user four shots without reloading, as opposed to only two without Akimbo. The attachment has little cost since the player cannot use the iron sights on the Ranger even without Akimbo. Being able to fire four shots helps at medium range when the target is too far away to be killed in one or two shots. It is also fairly accurate, despite what the Create-A-Class stats and common sense would say.
Akimbo Rangers are often seen in multiplayer due to their sheer power. Much of the skill using the Ranger requires knowing when to fire two barrels or only one when faced with multiple enemies and knowing when to fire two shells from one shotgun, which allows the player to reload only one shotgun with the other still available for defense. Akimbo Rangers greatly benefit from reload cancelling, as the time the shells are loaded are about half the time the reload animation lasts. A good sound to remember is the first "click" when the first shell(s) are apparently loaded; this is when one should reload cancel.
A single Ranger can boast a few attributes that its Akimbo counterpart (or the other shotguns in the game) can't. The single Ranger has the ability of being able to kill enemies within its maximum and minimum range almost all of the time without the need of the perks Steady Aim and Stopping Power. Since each player has 100 health total, the Ranger's damage-per-shot is potentially overkill, and can even instantly kill those with Painkiller. It only requires a minimum of 4 pellets (3 with Stopping Power) in order to kill a user with Painkiller. But the setback of the single Ranger is the constant reloading, especially when using both barrels simultaneously.
Knowing how to use the Rangers is crucial especially when using Akimbo, as the player will usually have no idea where enemies are, or how many there are. Therefore, it is recommended not to fire off all the shells into a single target, but rather, fire one off, and fire another if needed, then save the rest of the shells for just in case a group of enemies appear unexpectedly. Firing off all the shells into a single target can lead to ammo shortages, or a fatal encounter with an extra, unexpected enemy. To prevent fatal ambushes (with Akimbo), fire off only one side and during the reload for that particular side fire with the other side.
