Rust M79 Grenade Launcher and L85A1 Rifle: What the Commits Show

2026-11-10

Two new weapons are taking shape in Facepunch's commits: an M79 grenade launcher with high explosive, smoke and buckshot rounds, and an L85A1 rifle at an early blockout stage. Meanwhile the Uzi 9mm, which went live on November 5, is still getting changes.

None of the new weapons has a date. They are work in progress on their own branches and could change or be cut before they ship.

M79 grenade launcher

Alfie Birch has been working on a branch called M79_Grenade_Launcher since early November. The commits so far are art and setup:

On November 2, the blockout meshes were removed and the M79 viewmodel and materials were added, with follow-up viewmodel fixes.
On November 4, a world model for the M79 was added, so other players will see it in your hands.
Also on November 4, the 40mm grenades got world models, textures and basic prefabs for three types: 40mm HE, 40mm smoke and 40mm buckshot. Each one has a fired version too.

So far there is nothing about damage, crafting, loot or which tech tree it sits in. The commits are about the model and the rounds, so how strong it will be is still unknown.

This is our guess, from the three ammo types: the M79 looks set to be a single shot launcher that can blow things up, block sight with smoke, or work like a shotgun at short range.

L85A1 rifle

On November 4, pedro.a started a branch called L85A1 and added an L85A1 blockout. A blockout is a rough stand in model used to test size and shape before real art is made. That is all there is so far: one commit and no details on stats, ammo or how you would get it.

It is a very early sign, so treat it as something to watch, not something coming soon. Our earlier post on new weapons in the works covers the G3A3, lever action rifle and melee weapons that were spotted before this. The digest also shows lever action rifle animations started this week.

Uzi changes since launch

The Uzi 9mm shipped with the November 5 update. The launch version switches between the folded stock (automatic) and the extended stock (semi automatic) when you hold the fire mode button. Several commits change things around it:

One press to switch. On November 5, Martyn Chapman removed the need to hold the fire mode button. Changing the stock is now a single press. It is on the Uzi branch, so it is not confirmed live yet.
Stock folded when holstered. A November 6 commit makes the stock always fold when the Uzi is holstered and unfold when you pull it out. The commit says this is visual only.
A game tip. Equipping the Uzi now shows a tip if your fire mode button is not set.
Scopes. The 8x scope and variable scope are blocked on the Uzi.
Repair cost. Rin changed the Uzi repair cost so it no longer needs metal fragments.
Where it drops. Rin added Uzi loot spawns to hackable crates, elite crates and the underwater version of the normal crate, and says this may be revisited later. A follow-up by cipeaX keeps it from crowding out other guns in hackable crates and adds some ammo to the elite and underwater lab spawns.

The loot spawn commits were on main on November 4, the day before the update. The patch notes do not list where the Uzi drops, so we cannot confirm these spawns are live. For more on how the Uzi came together, see our Uzi commits post.

FAQ

Is Rust adding an M79 grenade launcher? Facepunch is building one. The commits show a model, a world model and 40mm HE, smoke and buckshot rounds. There is no date.

What is the L85A1 in Rust? A rifle that only exists as a blockout, a rough test model, in one commit from November 4.

How do you switch Uzi modes in Rust? At launch you hold the fire mode button. A commit changes that to a single press, but it is not confirmed live yet.

Where does the Uzi spawn? Commits add it to hackable crates, elite crates and an underwater crate. The patch notes do not confirm this, so it may change.
