Damage is one body hit up close, with no armour. A headshot multiplies it against players only. Damage per second empties one magazine and counts the reload. Velocity and spread are applied locally by your game client, while the server bounds their limits.

Chance is for one container opened or one NPC killed. Amount is how many it holds when it holds any. Condition is the state the item comes out in.
A repair bench charges 20% of the recipe to fix a broken item, less when it is only worn. A component in the recipe is charged as the first ingredient of its own recipe instead, or not at all when it has no recipe.
What the Custom SMG gives back in each recycler
| Recycler | Efficiency | You get |
|---|---|---|
| Red recycler | 75% | 6 High Quality Metal, 75% Metal Spring, 75% SMG Body |
| Green recycler (powered) | 60% | 4 + 80% High Quality Metal, 60% Metal Spring, 60% SMG Body |

| Yellow recycler | 40% | 3 + 20% High Quality Metal, 40% Metal Spring, 40% SMG Body |
The Custom SMG breaks down into High Quality Metal, Metal Spring and SMG Body.
A recycler takes one at a time.
Figures are for one item in perfect condition. Each recycler’s name opens its full table at this item. “4 + 80%” means 4 every time and a 80% chance of one more, and a percentage alone is the chance of getting one.

In Rust, Custom SMG is a ranged weapon in the Weapons category (item ID #1796682209, console shortname smg.2). Loaded with standard Pistol Bullet, it delivers 30 base impact damage from a 30-round magazine in active combat. Inventory storage holds a single unit per slot, and uncollected ground drops despawn after 40 minutes.
A rapid-firing Machine Gun. Sacrifices accuracy and distance for speed.
Crafting Custom SMG in Rust takes 25 seconds at a Workbench Level 2 once the 60 scrap blueprint node is unlocked, with all ballistics, crafting, and durability values read from the Rust game files. Shredding a spare copy at a green recycler recovers base materials at fifty percent yield (vs forty percent at safe-zone yellow units). Damaged copies repair at a Repair Bench for a fraction of recipe cost.
When choosing between Custom SMG and related weapons in Rust, prioritize researching a looted or traded copy at a Research Table (60 scrap) whenever you want to skip the 810-scrap tech tree path and save 750 scrap, or unlock the tech tree branch when your group also needs the prerequisite blueprints.
| Weapon | Damage | Fire Rate | Sustained DPS | Workbench / Source | Blueprint (Node / Path) |
|---|---|---|---|---|---|
| Custom SMG | 30 dmg | 600 RPM | 130.4 DPS | Workbench Level 2 | 60 node / 810 path |
| LR-300 Assault Rifle | 40 dmg | 500 RPM | 160.4 DPS | Military crate / Vendor | Uncraftable |
| Semi-Automatic Rifle | 40 dmg | 343 RPM | 91.1 DPS | Workbench Level 2 | 60 node / 930 path |
| MP5A4 | 37.5 dmg | 600 RPM | 163 DPS | Workbench Level 3 | 120 node / 420 path |

Loaded with standard ammunition, the Custom SMG deals 30 base damage per hit at 600 RPM (130.4 sustained DPS) in Rust, dropping to 80% damage past 42 m. Against a fifty-percent projectile-protection Metal Chest Plate, close torso hits deal fifteen net damage and down a full-health player in seven shots.
The Custom SMG fires HV Pistol Ammo, Incendiary Pistol Bullets and Pistol Bullets, 30 rounds to a magazine or 38 with an Extended Magazine in Rust. Holding the reload key (R) opens the ammunition selector to switch compatible rounds, with a 4-second reload timer.
Up to 4 weapon mods equip simultaneously on the Custom SMG in Rust across 15 compatible attachments: muzzle (Military Silencer, Muzzle Boost, Muzzle Brake, Oil Filter Silencer, Soda Can Silencer); sight (8x Zoom Scope, Holosight, Simple Handmade Sight, Variable Zoom Scope); underbarrel (Weapon flashlight, Weapon Lasersight); magazine (Extended Magazine); internal (Burst Module, Gas Compression Overdrive); targeting (Targeting Attachment).
The Custom SMG is crafted at a Workbench Level 2 from 8 High Quality Metal, 1 SMG Body and 1 Metal Spring, once the blueprint is learned in Rust. Non-craftable components like SMG Body must be looted from monument crates or recycled gear before queuing the craft at your bench.
The Custom SMG drops from 12 container and NPC loot tables in Rust, led by Supply Drop (39% chance), Elite Crate (2.8% chance), and Heavy Scientist (1.6% chance). Each listed probability reflects a single container opened or NPC killed, and found copies can be repaired or researched at base.
The Custom SMG recycles in Rust at an unpowered green recycler into 4 High Quality Metal, a 50% chance of a Metal Spring and a 50% chance of an SMG Body. Undamaged copies return the full listed yield, whereas worn items scale their recycler output down in proportion to remaining durability.
A repair bench fixes the Custom SMG from broken for 3 High Quality Metal in Rust. Repairing at a Repair Bench requires no learned blueprint or rare component body, scaling material cost to missing durability while permanently capping maximum condition by 20% across a full repair.
Dropped with nothing attached or inside in Rust, the Custom SMG despawns after 40 minutes by default. Picking it back up into a player inventory or storing it inside a base container immediately resets that ground despawn timer, which the server scales by item rarity tier.
The Custom SMG has 32-bit signed item ID 1796682209 and shortname smg.2 in Rust. Server plugins, custom loot tables, Vending Machine listings, and automated Industrial Conveyor filter strings reference these two identifiers under the Weapons category (stack limit 1 unit per slot).
Server administrators in Rust spawn the Custom SMG in the F1 developer console by typing inventory.give smg.2 1 or inventory.giveid 1796682209 1 for a single unit. Both console spawn commands require administrator or moderator privileges on the server, while regular players can bind a quick-craft shortcut key instead.
