Dirty Business Manufacture Weapons Guide — July 2026 | Dirty Business Wiki

Weapon manufacturing is one of the highest-risk, highest-reward production lines in Dirty Business. Where cannabis teaches patience, firearms teach precision: missing parts stall assembly, sloppy quality fails inspections, and leftover shavings generate evidence fast. This guide explains bench layout, parts flow, assembly order, quality tiers, and how to ship weapon contracts without jamming your entire base.

Prerequisites Before You Craft

Do not rush weapons on day one. You should understand orders, storage, workers, and disposal from the beginner guide, have stable cash from grow weed or counterfeiting, and a base upgraded enough for machine rooms—see upgrade base. Skipping fundamentals means one bad batch freezes income and spikes heat.

Review controls and keybinds for precise interactions at benches. Weapon steps often chain multiple stations; mis-clicks waste components.

Weapon Production Overview

The firearms line generally follows: source parts → machine or refine components → assemble receivers → fit barrels and triggers → quality check → package → deliver. Exact station names vary by Early Access build, but the dependency graph stays consistent: later steps cannot start without earlier outputs in storage or on benches.

Parts arrive through purchase orders, scavenged crates, or intermediate crafting. Keep a parts buffer so one missing screw does not idle three workers. The production hub maps weapon nodes alongside LSD and counterfeit chains.

Bench and Room Layout

Dedicated machine rooms reduce foot traffic and co-op collisions. Place in order of flow:

1. Parts storage near intake doors
2. Machining or cutting stations for raw metal work
3. Assembly benches for multi-step builds
4. Inspection table for quality rolls
5. Packaging adjacent to outbound storage
6. Disposal point on the exit path—mandatory

Power draw spikes when multiple machines run. Upgrade electrical capacity before doubling benches. Noise and security systems may tie into later patches; watch the updates page after each Steam patch.

Assembly Stages and Timing

Weapon assembly is rarely one button. Expect staged interactions: mount receiver, attach barrel, install trigger group, finish stock, test fire in a controlled range if available. Each stage consumes time and may consume disposable tooling.

Parallelize smartly. While one bench finishes machining, another operator assembles prior outputs. In co-op, split “machinist” and “assembler” roles instead of crowding one station.

Failed quality checks produce scrap. Scrap is not harmless—it becomes evidence unless processed. Route failures immediately to evidence disposal bins or burners.

Quality, Orders, and Buyer Requirements

Weapon buyers specify model type, quantity, condition, and sometimes serial restrictions or packaging format. Counterfeit serials may intersect with the counterfeiting line from production—do not mix workflows until you understand both.

Accept contracts only when parts inventory and bench time align. Weapons take longer per unit than weed bundles; reputation loss on failed gun orders is severe.

Use the complete orders guide for loading crates, vehicle capacity, and delivery timers. Heavy crates slow movement—plan carry paths through wide corridors.

Workers and Skill Assignment

Hire specialists once volume justifies wages. Generic workers may default to simpler tasks; assign explicitly to machining vs assembly if the UI allows priority tags. Details in hire workers.

Workers cannot invent missing parts. Maintain a shopping list on a whiteboard or shared co-op call—communication beats assumptions.

Risk, Heat, and Evidence

Weapons generate metal shavings, failed parts, oily rags, and test rounds. Every piece counts toward heat if left on floors. Schedule disposal sweeps between batches, not at end of day.

Test firing may create auditable noise or special waste types. Run tests during low activity periods and dispose of casings immediately.

If police pressure or raid mechanics trigger in your build, secure finished goods in locked storage and keep active benches clean. For mechanic specifics, cross-read evidence disposal and community notes on tools.

Scaling Production

Second assembly lines need duplicate parts buffers and redundant inspection. Bottleneck analysis:

• If machining backs up, add lathes or hire a machinist-dedicated worker.
• If inspection backs up, quality failures may be too high—fix upstream steps before adding inspectors.
• If delivery backs up, upgrade vehicles or split co-op carriers.

Fund expansions with steady side income from grow weed until weapon margins cover capital costs alone.

Demo and Early Access Notes

The free demo introduces production concepts but may not expose the full weapon tree. Early Access players should expect balance shifts—recipes, timers, and part costs change. After patches, re-run a small test batch before accepting bulk orders.

For broader critique of combat economy and progression pacing, see the review. For stuck interactions at benches, try controls troubleshooting.

Weapon manufacturing separates organized operators from chaotic ones. Build the line once, keep it fed with parts, and never let scrap hit the floor.
