The R93 is the middle-ground between the quick-fire Rattlesnake sniper rifle and the high-damage Thanatos .50 cal. Because of this, the R93 is particularly effective against special enemies at long range, while still being efficient at dealing with standard enemies, thanks to its ammo count.
Outside of Death Wish difficulty, it has the ability to kill any enemy besides the Bulldozer with a single headshot. For weaker cops, especially on low difficulties, even bodyshots are sufficient. On Death Wish, the Taser and Cloaker can each be killed with a headshot plus a body shot.
The biggest weakness of the R93 is its small magazine of 6; while most shots on target result in a kill, the sheer number of enemies that appear during assaults make crowd control difficult with the R93 alone, so care should be taken with aiming and one should attempt to kill multiple enemies with 1 shot if the opportunity presents itself, for maximum ammo efficiency.
Additionally, while it has a somewhat low total ammo count of 30; the R93 recovers 1 round per ammo pickup from fallen enemies, so provided one does not miss too many shots, it is possible to fill up one's entire ammo count again by just picking up ammo drops from dead enemies.
Good stopping power and ammo efficiency; can oneshot any non-special with body hits, and oneshot any special with one headshot (Bulldozers, under certain circumstances, can be killed with one headshot as well, see below).
Reasonable rate of fire
Good stability once mods are installed.
Makes for a very capable and reliable close-quarters sniper rifle because of its decent statline and stopping power.
Very limited magazine capacity
Poor maximum ammo
Mods must be unlocked by completing specific achievements
The R93's meager reserve of ammunition may prove troublesome during prolonged firefights, so bring an Ammo Bag or have Fully Loaded aced to make sure you never run out of ammo. Bringing an ammo efficient secondary will also help to conserve ammunition and to allow more chances to gather ammo pickups.
Replacing the stock sight with a Milspec Scope or similar high zoom level optic will remove the scope sway encountered when using the stock sight, making it easier to land repeated shots taken in rapid succession.
Although the main flashlight has a toggle switch, the laser sight component of the LED Combo is pressure-activated, meaning the laser will stay on as long as the pressure switch is depressed. This switch is not placed where it should be, however (on foregrips, magazine wells, etc...) and is instead ziptied to the main taclight, leaving no plausible mean for the user to toggle it without awkwardly moving their off hand off the weapon and gripping the attachment itself.
While aiming down sights with this gadget, the bullets will land directly on the tiny circle of the sight, not above it. In other words, obscure your target with the small circle to it. While hip firing, the sight lines up relatively close to target, allowing easy hip fire shots at close range. However, sniper rifles overall suffer from an extremely large hipfire cone of fire; aiming down sights is highly recommended.
The Angled Sight can be installed along with another sniper scope, and does not replace the default sniper scope if installed without one.
Requires a pre-installed sight mod to mount. The magnification level can be changed while aiming down the sights, and the aiming FOV will automatically adjust itself. Not compatible with the Acough Optic, Military Red Dot, Milspec Scope, Combat Sight, Reconnaissance Sight, Theia Magnified Scope, Box Buddy Sight, the JP36's Original Sight, the Raven's Flip-up Sight or the GROM and Platypus 70's iron sights. Currently bugged and not appearing as intended on certain weapons, for a list see here. They're still listed below even if broken.
Upon release, the default reticle of this sight was a chevron instead of the retail version's red dot. After the release of the Gage Mod Courier DLC, it was reverted to the regular sight's red dot.
It is functionally the same as the standard Military Red Dot Sight, but the sight's casing is tan instead of black with the line "A-10" scrawled on near the adjustment knob. The sticker on the lens cap's interior also says "I <3 Payday" instead of having a picture of an American flag.
This sight was based on the Aimpoint CompM2 optic. While it is portrayed as a high-zoom scope in-game, the CompM2 is actually a reflex sight, meaning it offers no magnification in reality.
In its original setup, this is your standard high spec telescopic sight, but it's been fitted with some auxiliary software and hardware, which adds the following functions:
Range Finder Allows you to accurately measure distances up to 200m, displayed on the actual unit and in the reticle. Practical use for this is dubious at best considering that bullets in Payday 2 use hitscan mechanics and have no simulated gravity or windage effects. Furthermore, very few in game locations exist where targets can be engaged from even remotely close to 200 meters away. However, it can be extremely helpful in obtaining the Far, Far Away achievement, as it makes identifying enemies that are at 40m or further much easier.
Auto-Tagger In stealth, the scope will automatically tag any enemy you sweep your sights over, and once the alarm has been sounded, it'll auto-tag specials. This acts similarly to the effects of High Value Target Aced, and having the skill will also cause the increased damage and mark duration.
Note: Due to a bug in the current version of the game, this scope is unable to mark enemies in stealth. This is not intended.
The Theia Magnified Scope's in-game optic is extremely simplified compared to the real BORS. The system, when paired with a magnification scope, would show indications of humidity, environmental temperature, barometric pressure and projectile elevation/depression for precise compensation, which the in-game scope lacks, though seeing as every sniper rifle in the game uses a hitscan system to determine shot placement, the other miscellaneous functionalities are likely not needed.
When aiming down the sight, there is a dim "Y" above the "M" that stands for meters. This dimmed letter would stand for Yards, a different unit of distance measurement. Since the game only uses the metric system, the reason for this being there isn't exactly clear.
The Theia Magnified Scope currently has the largest magnification in the game.
In Greek mythology, Theia was the Titan goddess of sight and shining light of the clear blue sky.
The method of obtaining the sight is ironic to an almost bizarre degree as it's intended for precision shots at long range and not for something that in reality would be haphazard to the point of being insane (i.e. Zip-line Rifling).
Despite being based upon a dedicated night scope with tinted lens, the Box Buddy Sight provides the same clear sight picture as any other optic in the game when aimed through during daytime or in areas with bright lighting.
The R93 was based on the Blaser R93 Tactical 2, as evident by its LRS2 chassis and claimed caliber of .338 Lapua Magnum.
It can be mocked up to vaguely resemble the original hunting variant of the R93 with the Wooden Body equipped, though with a more squared grip and the Tactical model's muzzle brake and removable magazine remain visible on the weapon.
It also is one of the few weapons in-game to retain its real name, or at least parts of it.
It is one of few weapons in PAYDAY 2 with a unique pose on the main menu. The pose the character uses with the R93 equipped will have him/her hold the gun up and press its stock against their shoulder, as if aiming at someone/something through the scope.
