Assault rifle

The assault rifle is a moderately heavy, automatic ranged weapon which fires 3-shot bursts of rounds which deal a moderate amount of damage each; a slightly shorter delay between each shot; a moderate time between bursts; slightly longer range and moderate overall accuracy.

Acquisition

Assault rifles can be crafted at a Machining table once the Precision rifling research project has been completed. They require 60 Steel, 7 Components, 40,000 ticks (11.11 mins) of work, and a Crafting skill of 6.

They can also be found in ancient shrines or purchased from outlander and orbital combat suppliers, and outlander faction bases. They can also be found on the following raider kinds:

Raider Kind	Chance	Average Quality	Health
Mercenary Gunner	9.17%	Normal	70-320%
Elite Mercenary	53.37%	Normal	100%
Boss	53.37%	Normal	100%
Ancient Soldier	10.81%	Normal	100%
Trooper	?	?	70-230%
Janissary	?	?	70-230%

Analysis

The assault rifle is the jack-of-all trades of RimWorld's firearms. Single-target damage is respectable, with accuracy and warmup time being good overall. Range is amazing - it's tied with the minigun for best of the multi-shot firearms (that are not consumable). Having high range, along with good damage and accuracy, is a powerful niche on its own.

In terms of actual damage, the assault rifle is consistently higher than the LMG, lower than the heavy SMG until beyond short range (12 tiles), and generally outdamaged by the charge rifle. Either rifle is completely outdamaged by less flexible weapons like the minigun and chain shotgun. It is a moderately skill friendly-weapon, though the heavy SMG tends to fill that niche better. You may want to give weaker shooters some even cheaper weapons, like the machine pistol, instead.

The assault rifle can be used to good effect in virtually any use case, whether in close-quarters, out hunting, or on the field. The only real thing that the assault rifle lacks is stopping power, as it's unable to stagger humans. Another downside is that production is quite expensive, though not as expensive as a charge rifle. You won't see raiders use assault rifles until the midgame.

Stats

Against an unarmored human, an assault rifle can kill with 4 hits to the torso, 3 hits to the head or neck, or 1 hit to the brain; cripple or destroy limbs in 3 hits; and cripple or destroy eyes and digits with a single hit. It'll generally take around 6 hits (~9.3 seconds average) to incapacitate that human from pain shock.
