Laser Sight on Guns in Project Zomboid (Build 42.19)
Build 42.19 · vanilla weapon part · seven compatible firearms
Quick answer
Laser Sight is a firearm attachment that mounts on the Canon slot. With a screwdriver you can attach or remove it on seven guns. Live stats: +5 hit chance, faster aim (−10 aiming time), item weight and equipped weight both 0.6. Extra weight is a cost, not a benefit. Compatible guns: M9, M1911, B-F Pistol, M16, M1A, Trapper Carbine, and MSR7T Tactical Rifle.

If you still see older guide numbers
Some older write-ups list weight 0.2, only five mount guns, and no aiming-time bonus. In Build 42.19 the bag and equipped weight are both 0.6, the aiming-time bonus is present, and two extra mounts were added: Trapper Carbine and MSR7T Tactical Rifle. Display names also shifted: the third pistol is B-F Pistol (not “D-E”), and the .308 rifle is M1A Rifle (not “M14”).
What the stats do
- Hit chance +5 — improves accuracy while the part is mounted. Matches the in-game tooltip: increases firearm accuracy.
- Aiming time −10 — you settle the sight faster. Easy to miss if you only look at hit chance.
- Weight 0.6 / +0.6 when mounted — the part itself weighs 0.6 and adds 0.6 to the gun’s carried weight. That is a load cost, not a combat upside.
How to attach or remove
- Have a Screwdriver available for the attach/detach check.
- Open the firearm’s weapon-part menu and install Laser Sight on the Canon slot (or remove it the same way).
- Only the seven firearms below accept this part. Other weapons will not offer a valid install target.
For the general attachment workflow across all part types, see how to equip weapon parts.
Canon slot conflict
Laser Sight uses the Canon slot. On handguns that also accept a gun light, the light shares the same slot, so you cannot run Laser Sight and a Canon-slot light together on one gun. Choose accuracy (laser) or the light’s illumination stats—not both in that slot.
Compatible firearms (all 7)
These are the seven firearms that accept Laser Sight in Build 42.19, with English display names.
| Display name | Caliber / role | Notes |
|---|---|---|
| M9 Pistol | 9mm handgun | Common early sidearm |
| M1911 Pistol | .45 handgun | Higher per-shot punch than the M9 |
| B-F Pistol | Handgun | Older guides often called this “D-E” |
| M16 Assault Rifle | 5.56 rifle | Full-auto capable assault rifle |
| M1A Rifle | .308 rifle | English name is M1A (not M14) in 42.19 |
| Trapper Carbine | Carbine | Not on many older five-gun lists |
| MSR7T Tactical Rifle | Tactical rifle | Not on many older five-gun lists |

What you see on the gun
- Attachment model: On compatible guns the Laser Sight model can appear on the weapon when mounted. The inventory icon is the handgun laser graphic.
- Projected beam / red dot on the world: Vanilla Laser Sight does not add a world-projected laser beam or light cone (unlike a gun light’s torch). Treat the hit-chance and aiming-time bonuses as the real benefits; do not expect a visible pointer on zombies or walls unless a mod adds one.
