A repair bench charges 20% of the recipe to fix a broken item, less when it is only worn.
What the Muzzle Boost gives back in each recycler
| Recycler | Efficiency | You get |
|---|---|---|
| Red recycler | 75% | 7 + 50% High Quality Metal |
| Green recycler (powered) | 60% | 6 High Quality Metal |
| Green recycler | 50% | 5 High Quality Metal |
| Yellow recycler | 40% | 4 High Quality Metal |
The Muzzle Boost breaks down into High Quality Metal.
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. “7 + 50%” means 7 every time and a 50% chance of one more.
In Rust, Muzzle Boost is a weapon attachment in the Weapons category (item ID #-1405508498, console shortname weapon.mod.muzzleboost). Weapon modding mounts this muzzle attachment across 21 compatible ranged weapons. Inventory storage holds a single unit per slot, and uncollected ground drops despawn after 40 minutes.
Increases weapon fire rate by channeling gasses back into the weapon cycling it faster, at the cost of bullet accuracy.
Crafting Muzzle Boost 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 Muzzle Boost and related weapons in Rust, prioritize researching a looted or traded copy at a Research Table (60 scrap) whenever you want to skip the 750-scrap tech tree path and save 690 scrap, or unlock the tech tree branch when your group also needs the prerequisite blueprints.
| Item | Category | Stack Limit | Craft / Source | Tech Tree / Research | Green Recycler Yield |
|---|---|---|---|---|---|
| Muzzle Boost | Weapons | 1 per slot | Workbench Level 2 | 60 node / 750 path | Not recyclable |
| Weapon Lasersight | Weapons | 1 per slot | Workbench Level 3 | 60 node / 180 path | Not recyclable |
| Burst Module | Components | 1 per slot | World loot / gather | No blueprint | Not recyclable |
| Holosight | Weapons | 1 per slot | Workbench Level 2 | 60 node / 990 path | Not recyclable |

The Muzzle Boost takes the muzzle slot and shortens the time between shots by 10% on 21 ranged weapons in Rust, including Assault Rifle, Bolt Action Rifle, Custom SMG, Handmade SMG, HMLMG, L96 Rifle and 15 other firearms.
The Muzzle Boost is crafted at a Workbench Level 2 from 10 High Quality Metal, once the blueprint is learned in Rust. Raw ores smelt into metal inputs in a furnace while non-craftable components must be looted from monument crates before queuing the craft at your workbench.
The Muzzle Boost drops from 9 container and NPC loot tables in Rust, led by Locked Crate (1.3% chance), Elite Crate (0.78% chance), and Scientist PT Boat Dry Box (0.73% chance). Each listed probability reflects a single container opened or NPC killed, and found copies can be repaired or researched at base.
The Muzzle Boost recycles in Rust at an unpowered green recycler into 5 High Quality Metal. Monument green recyclers shred items one unit at a time on fast radtown cycles, whereas safe-zone yellow units trade lower material recovery for peacekeeper protection.
The Muzzle Boost takes 25 seconds to craft, down to 12.5 seconds at Workbench Level 3 in Rust. It sits in the Weapons catalog with item ID -1405508498 alongside 84 related weapons, with F1 console command inventory.giveid -1405508498 1 across 85 published Weapons entries.
A repair bench fixes the Muzzle Boost from broken for 2 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.
Blueprint progression for Muzzle Boost at Workbench Level 2 in Rust charges 60 scrap on the target node and 750 cumulative scrap along the prerequisite branch, while direct blueprint study at a Research Table charges 60 scrap.
Dropped on the ground in Rust, the Muzzle Boost 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 Muzzle Boost has 32-bit signed item ID -1405508498 and shortname weapon.mod.muzzleboost 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 Muzzle Boost in the F1 developer console by typing inventory.give weapon.mod.muzzleboost 1 or inventory.giveid -1405508498 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.
