Crack open an airdrop and there is a decent chance a long, black rifle is sitting inside. That is the M39 Rifle, Rust’s military grade semi auto. It hits as hard as an AK per shot, it is pinpoint accurate, and you cannot craft it, research it or put it on the tech tree.
This M39 Rust guide covers the gun’s real stats, every place it drops, how to buy one at Bandit Camp, how it stacks up against the SAR, AK and LR-300, the best ammo and attachments, what it recycles into and how many shots it takes to kill.

What Is the M39 Rifle in Rust?
The M39 is a semi automatic designated marksman rifle that fires 5.56 Rifle Ammo. Its in-game description is simply “Military grade semi auto rifle”, and in the game files it is rifle.m39 with item ID 28201841 (see our Rust item IDs list).
Think of it as the big brother of the Semi-Auto Rifle. Both fire one bullet per click, but the M39 does 50 damage instead of 40, carries 20 rounds instead of 16 and is more accurate. Because it is semi auto, there is no spray pattern to learn: your rate of fire and your recoil both come down to how fast and how calmly you click.
The trade-off is supply. The M39 sits in the same military tier as the L96, M249 and LR-300. There is no blueprint, so every M39 you use is one you looted or bought. Lose it and you go back to hunting for another.

Where to Find the M39 in Rust
The M39 only spawns in high tier loot. These are the approximate chances per container from current loot tables (they shift a little between updates):
| Source | Chance | Where |
|---|---|---|
| Supply Drop | ~18% (1 to 2 rifles) | Server airdrops and thrown Supply Signals |
| Elite Crate | ~1% | Launch Site, Military Tunnels, Underwater Labs |
| Heli Crate | ~1% | The wreck of a downed Patrol Helicopter |
| Bradley Crate | ~0.5% | Crates left by the Bradley APC, plus its heavy scientists |
| Tunnel Dwellers | Carried weapon | The underground rail network |
| Bandit Camp Black Market | Always in stock | 400 scrap |
If you want an M39 on purpose, Supply Drops are the only reliable route. Around one in five drops has one, so a team that farms a few Supply Signals or fights over server airdrops will see it far more often than anyone looting elite crates. Tunnel dwellers, the 125 HP scientists below the rail network, are the other reason to see M39s early in a wipe, because they fight with one.
How to Buy the M39 at Bandit Camp
The Black Market at Bandit Camp sells the M39 for 400 scrap. You walk away with a working rifle, no blueprint, research or workbench needed. It is 100 scrap cheaper than the LR-300, which is why many players grab the M39 when they cannot quite afford the LR.
Bandit Camp is a safe zone, so stash your gear first and do not aim a weapon at anyone inside or the guards will open fire. If you are short on scrap, our Rust scrap guide covers the fastest ways to farm it.
M39 vs SAR vs AK vs LR-300
| Rifle | Damage | Fire mode | Magazine | How to get it |
|---|---|---|---|---|
| M39 | 50 | Semi, ~343 RPM | 20 | Loot, 400 scrap at Bandit Camp |
| Semi-Auto Rifle | 40 | Semi, ~343 RPM | 16 | Craft at Workbench 2 |
| Assault Rifle (AK) | 50 | Auto, 450 RPM | 30 | Craft at Workbench 3 |
| LR-300 | 40 | Auto, 500 RPM | 30 | Loot, 500 scrap at Bandit Camp |
- M39 vs SAR: a straight upgrade. 25% more damage per shot, 4 more rounds and a tighter aim cone. If you find an M39, your SAR becomes a backup.
- M39 vs AK: the M39 wins at mid to long range because every shot lands where you aim. The AK wins up close, where 30 rounds of full auto beats anyone clicking.
- M39 vs LR-300: the LR is the easier gun to win close fights with. The M39 hits harder per bullet and is the better pick for holding an angle or a compound wall.
For the full weapon ranking, see our Rust weapons tier list, where the M39 sits in S tier.
Best M39 Ammo and Attachments
Ammo. The M39 fires the same 5.56 as the AK, SAR, LR-300, Bolt Action Rifle and M249:
- 5.56 Rifle Ammo: the default and the best value. 50 damage a shot.
- HV 5.56: faster, flatter bullets for long range shots, at a small damage cost.
- Incendiary 5.56: sets things on fire but leaves a bright tracer that gives away your position.
- Explosive 5.56: a soft raiding round, weak against players. See our explosive ammo guide.
Attachments. The M39 takes the full rifle attachment set:
- Holosight: 20% tighter aim cone and a clean sight picture. The best all-round pick.
- 8x Zoom Scope or Variable Zoom Scope: turns the M39 into a proper marksman rifle, at the cost of 50% more recoil.
- Extended Magazine: 20 rounds becomes 25.
- Weapon Lasersight: 20% tighter aim cone and much better hip fire.
- Burst Module: fires short bursts instead of single shots, with less recoil and spread per shot. You get it by recycling a Prototype 17.
- Muzzle Brake: halves recoil but costs 15% damage.
- Silencers: hide your muzzle flash and sound for roaming, but cut damage and bullet speed.
M39 Recycle Yield
Put an M39 in a recycler and you get:
- Monument recycler: 30 High Quality Metal, 3 Metal Springs and a 60% chance of a Rifle Body.
- Safe zone recycler (Outpost, Bandit Camp): 20 HQM, 2 Metal Springs and a 40% chance of a Rifle Body.
No scrap comes back. Recycling only makes sense if you have spare M39s and need a Rifle Body for an AK or Bolt Action Rifle; otherwise, keep the gun. A dropped M39 despawns after 40 minutes on the ground.
M39 Shots to Kill
Players have 100 HP. With standard ammo at close range, before damage falloff kicks in:
| Target | Shots to kill |
|---|---|
| No armor | 2 body shots, or 1 headshot |
| Metal Facemask (blocks 50%) | 2 headshots |
| Hazmat Suit (blocks 30%) | About 3 body shots |
| Metal Chest Plate + Hoodie (about 45%) | About 4 body shots |
Arm and leg hits do less, and damage drops off at long range, so treat these as best-case numbers. The lesson is simple: aim for the head. Even through a facemask, two clean headshots end the fight. For more on gear, see our Rust armor guide.
Tips for using the M39
- Pace your clicks. Spamming the trigger throws off your aim. A steady rhythm keeps every shot on target.
- Fight at range. Hold roofs, compound walls and monument angles. Avoid running into close fights against AKs and shotguns.
- Put a holosight on it first. It is the cheapest big upgrade for the gun.
- Do not roam with it carelessly. There is no blueprint, so a lost M39 is gone until the next airdrop.
Every gun you own disappears on force wipe. Check when the next Rust force wipe is so you know how long your M39 has left.

Where is the best place to find an M39 in Rust?
Supply Drops. Each one has roughly an 18% chance of holding an M39, far higher than elite crates, heli crates or Bradley crates, which sit around 1% or less. Tunnel dwellers in the underground rail network also carry the M39.
How much damage does the M39 do in Rust?
