Searching for the heavy gun parts blueprint in ARC Raiders usually means one thing: you want to turn a rare schematic into a weapon you can actually use. The difficult part is not simply finding a blueprint. It is lining up the schematic, workshop level, and supporting materials before valuable loot sits in storage with no practical purpose. For players comparing ARC Raiders BluePrints, the Hullcracker is a useful case study because Heavy Gun Parts directly affect whether the plan is ready to become a finished weapon. Why Heavy Gun Parts Matter Heavy Gun Parts are easy to undervalue when viewed as individual salvage. Their real value appears when they complete a high-impact recipe. The Hullcracker requires three Heavy Gun Parts, plus a Magnetic Accelerator and an Exodus Module. It is also tied to the Gunsmith reaching Level 3, so collecting parts alone does not guarantee immediate access to the craft. That creates a simple planning rule. ◆ Keep Heavy Gun Parts when you are close to the Hullcracker recipe. ◆ Judge the full recipe rather than the value of one isolated component. ◆ Treat the Gunsmith requirement as part of the weapon's actual cost. This approach prevents a common mistake: trading away useful parts, then discovering that replacing them takes several more successful extractions. How the Hullcracker Blueprint Fits Into Progression The reported route to the Hullcracker schematic runs through The Major's Footlocker in Tian Wen's quest line. The objective sends raiders to the Ruby Apartments, where the relevant container is on the second floor after entering from the northwest side. Recovering Major Aiva's Mementos and completing the quest provides the blueprint route, assuming the information remains accurate in your version of the game. The important lesson is that blueprint progress and material progress should move together. If The Major's Footlocker is already your next objective, start protecting Heavy Gun Parts instead of treating them as spare trade value. If the schematic is already learned, set a clear target of three parts and gather the Magnetic Accelerator and Exodus Module before spending those components elsewhere. When Should You Trade or Save Them? Heavy Gun Parts have value outside the Hullcracker path as well. A rotating trade selection in Speranza has included them, which gives players another way to solve a material shortage. That option is helpful, but it also creates a meaningful choice. ◆ Save the parts if you already own the Hullcracker blueprint and need only one or two more. ◆ Consider trading when you lack the schematic, workshop level, or several other recipe components. ◆ Avoid using rare materials for a short-term exchange unless it clearly advances a near-complete plan. There is no universal answer for every account. A player with Level 3 Gunsmith access and two Heavy Gun Parts has a strong reason to preserve them. Someone still far from the blueprint may gain more from a trade that supports immediate progression. Safer Raid Decisions Make the Plan Work Blueprint-critical loot changes how a raid should be played. Once you recover the schematic or the final Heavy Gun Part, optional loot becomes less important than extraction. Secure storage is especially valuable for a newly recovered blueprint, while a safer route is usually preferable to extending a successful run for one more item. Think of the goal as converting loot into permanent progress. The Hullcracker only pays off after the schematic is learned, the Gunsmith reaches Level 3, and all five required components are ready. As a professional platform for buying game currency or items, U4GM offers a convenient option, and you can purchase u4gm ARC Raiders BluePrints when that fits your progression plan. Save Heavy Gun Parts when a complete craft is close, and trade them only when the exchange solves a more immediate need.
