El Muro is a Resolver weapon that pairs a shotgun hand cannon with a homemade riot shield. You can buy it from Juan straight away, and it lets you push into close fights while the shield soaks bullets.
It is built for close quarters. Raise the shield, walk into a room and fire point-blank. It is weak at range, so it is not a general-purpose weapon.
Buy it from Juan with Depleted Uranium. There is no rank requirement.
You can upgrade to a Reinforced Shield or a Blunt Shield, add Serrated Edges, and switch between shotgun shells and slugs.
The long reload is the big weakness. Make your last shots count or duck into cover before you reload, or you risk getting swarmed.
Auto-Crossbow
The Auto-Crossbow, called the Executioner in Far Cry 6, is a semi-automatic crossbow you carry as a special weapon. It returns from Far Cry 4 and looks like a stockless BZ19 with a helical magazine.
Auto-Turret
The Auto-Turret is a deployable gadget that you place and then leave to shoot enemies on its own. It is handy for guarding a flank, and FND Engineers use their own turrets against you.
Compound Bow
The Compound Bow is a silent bow for stealth kills and hunting in Far Cry 6. Arrows make no noise, so you can drop guards without alerting a base, and its unique version is the brightly painted Bullseye.

Discos Locos is a Resolver weapon that launches CDs as blades while it plays salsa music. Hip-fire shatters discs into shotgun-style shrapnel and aimed fire throws them whole, so it works at close and mid range.
