The sniper rifle is a slightly heavier, single-shot firearm in RimWorld which deals a high amount of damage per shot; a long time between shots; very long range and high overall accuracy.

Acquisition

Sniper rifles can be crafted at a Machining table once the Precision rifling research project has been completed. They require 60 Steel, 8 Components, 45,000 ticks (12.5 mins) of work, and a Crafting skill of 7.

Sniper rifles can also be purchased from outlander and orbital combat suppliers or from outlander faction bases, or recovered from raiders:

Mercenary Sniper	99.89%	Normal	70-320%

Analysis

Sniper rifles have the longest range of all weapons, along with excellent long-distance accuracy. With high per-shot damage, they have a propensity to destroy limbs. Therefore, they are a poor choice if you intend to take prisoners after a raid.

While per-shot damage is high, snipers have a sluggish firerate. Their actual DPS is among the worst of firearms, just on par with the neolithic greatbow. Thus, snipers are a poor "general" weapon. If range is important, though, then snipers are a strong choice. They can be used to provoke sieges, kite centipedes, or be one of the safest weapons to hunt with. Due to poor DPS and slow firerate, it is a tedious weapon to kite with and should generally be avoided unless you really need the range.

As a shooter's personal accuracy is reduced for each tile of distance, sniper rifles are one of the most skill-heavy weapons in the game. For example, a shooter with a Shooting Accuracy of 95% (Shooting 6) would have a 0.95^30 chance, or only ~21%, to hit a target from 30 tiles. This is regardless of weapon - weapons apply another penalty after shooter-side accuracy. In contrast, a shooter with Shooting Accuracy 99% (Shooting 20) would have a ~74% shooter-side chance to hit, a DPS increase of +252%. If using a sniper for long-range combat, then have your highest skill shooters wield it.

Compared to the bolt-action rifle, the sniper rifle has worse firerate, DPS, and close-range accuracy in exchange for higher range, extra per-shot damage, and improved long-distance accuracy. The sniper rifle is more expensive, has a larger research requirement, and isn't common from raiders (barring sniper-only mercenary raids).

Stats

Against an unarmored human, the sniper rifle can kill with 2 shots to the torso or 1 shot to the head, brain or any vital organ. It'll generally take around 3 hits (~20.9 seconds average) to incapacitate that human from pain shock.
