💰 Heavy Gun Parts Blueprint

The Heavy Gun Parts Blueprint is a rare Refiner II recipe in ARC RAIDERS that permanently unlocks the ability to turn 4× Simple Gun Parts into valuable Heavy Gun Parts, the material used to craft, repair, and upgrade weapons that fire heavy and shotgun ammo across all tiers. Dropping from topside loot like high-tier containers and grenade cases, this blueprint is basically your upgrade pass for big-damage builds—grab it once, learn it, and you can keep recycling low-tier junk into fuel for your hardest-hitting guns.
