The M16 A1 is a fast-firing assault rifle with a small 20-round magazine. You get it from the High Supply treasure hunt, and its two variants come from another treasure hunt and a Special Operation.
It works as an aggressive close-to-mid range rifle that shreds unarmored soldiers. The low damage per round and short magazine mean you reload often, so it is weaker in long fights than higher-capacity rifles.
Complete the High Supply treasure hunt for the standard rifle. Do A Rising Tide for Camo Quinceañera and the Malagua Special Operation for Decontaminant.
It takes standard, armor-piercing, soft-target, poison, blast and incendiary rounds. Muzzle, optic and laser sockets accept suppressors, ACOG and reflex sights. Camo Quinceañera trades a little damage for better accuracy, handling and stealth.
45/70-T
The 45/70-T is a lever-action rifle with a four-round tube. It hits hard per shot for a rifle, and Matéo Serrano's insurgency rewards its unique version, Vaquero Del Espacio.
AK-47
The AK-47 is the rifle most FND soldiers carry and the symbol of Libertad's revolution in Far Cry 6. It is a dependable 30-round assault rifle you can buy or find early, with Death Rites and Min Maxed as its unique versions.
AK-M
The AK-M is a modernised AK with slightly more punch and accuracy than the AK-47. It fills the same 30-round assault rifle role, and its unique versions include Fuck Antón, Royal Mint and the Lost Between Worlds rifle Red Fractured.
