B42 Rain's Firearms & Gun Parts

A complete overhaul of the vanilla Project Zomboid firearms and gun attachments. Somewhat lore-friendly or vanilla+.

This is very much a work in progress. B42 unstable broke literally every lua script I had in B41.78, all my suppressors, every AnimSet I had customized, and obviously every single item & weapon script file as well. Expect bugs all the way until B42 goes stable, and even after that. I am soloing this thing.


If your character has never in their lives even held a firearm (Aiming 0), their accuracy with especially pistols and more "advanced" types of guns will reflect that experience level. Shotguns and especially sawn-off shotguns are your best option to level up your Aiming, because they are much more forgiving to unskilled shooters than a handgun would be for example. Once you get your character to Aiming 5, all the guns will be accurate. Especially if you use some of the attachments that improve accuracy. Aiming 6 and above will start turning your character into John Wick.

7.62x39 and 7.62x51

60-round magazines for 9mm and .45 ACP automatic weapons.
50-round magazines for 5.56, 7.62x39 and 7.62x51 automatic weapons.

"A regular at the local firing range." +1 Aiming, +1 Reloading, and +1 Nimble. -6 points.

9mm Suppressor
.45 ACP Suppressor
.223/5.56/7.62x39 Suppressor
.308/7.62x51 Suppressor
12g Suppressor
12g Suppressor (Improved)
Homemade Suppressor
Suppressors reduce (but do not eliminate) the sound level of gunshots. Lower caliber weapons are more suppressed than higher caliber ones.
For example, 9mm guns with a suppressor are about as loud as a running generator. The homemade suppressor is not nearly as effective as the other ones.

Fiber Optic Sight: Small bonus to accuracy and range
Red Dot Sight: 2x as effective as the Fiber Optic Sight
SOCOM Red Dot Sight: Rare military issue red dot, 3x as effective as the Fiber Optic Sight
x4-x12 Scope: Small increase to minimum range, big increase to maximum range
Double Barrel Shotgun Choke Tube: Self-explanatory
Shellholder: Increases a shotgun's reloading speed
Improved Recoil Pad: Attacheable to shotguns as well
Marksman's Recoil Pad: Far more effective recoil pad for rifles
Compensator: Reduces a pistol's recoil and helps slightly with accuracy
x4 ACOG Scope: Increases both minimum and maximum range, along with accuracy. Small penalty to aiming time.
x8 ACOG Scope: Increases both minimum and maximum range, along with accuracy. Penalty to aiming time.
Foregrip (Tactical/Wood): Reduces recoil, allows for quicker aiming, and very slightly helps with accuracy.

Military Pouches & Military Pack. Similar to the Military Backpack, and all three can be worn together. The Military Pouches also provide Webbing attachments.

Massive thank you to Nik for the lever action animations!

No it will not.
For most people, yes. If you want to be extra safe, backup your save first.
Have a screwdriver, the gun, and the attachment in your main inventory. Right click the gun -> Upgrade.
NO!
Choose one or the other, not both.
