The MS16 is a hard-hitting single-shot battle rifle in a long L and a short S version. The best pick is Surf & Turf, an MS16 S unique from the Crocodile Tears treasure hunt.
Use it like a semi-sniper. Each shot hits hard and travels well, so it rewards careful aim at mid to long range. It is slow for close fights where an automatic rifle does better.
Complete Crocodile Tears for Surf & Turf. Sharkbite is a unique MS16 L, and a Libertad Custom MS16 L also exists.
It takes standard, armor-piercing, soft-target, poison, blast and incendiary rounds. You carry 120 rounds, or 180 with the Assaulter Pocket.
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
