JAR-5 Dominator: Rechambered
Ministry of Defense — Procurement Notice
The Ministry of Defense has authorized a field conversion for the venerable JAR-5 Dominator, reconditioning the rifle's chamber to accept the explosive gyrojet cartridges originally developed for the P/40-K sidearm program. Helldivers wielding the Dominator have long prized its stopping power against armored threats but field reports consistently noted the rifle's 15×100mm ammunition lacked the terminal effect required to breach the heaviy enemy armor now encountered across the galaxy.
This conversion corrects that deficiency — and then some. The Rechambered Dominator fires the same rocket-propelled, high-explosive warhead as the P/40-K, loaded behind a hotter and larger gyrojet rocket which drives the round to 380 m/s — more than double the stock round's 180. Heavy armor penetration and explosive fragmentation on impact now with the veloctity and maximum range of a rifle.
Managed Democracy demands overwhelming firepower. This conversion ensures it.

What this mod does: Rechambers the JAR-5 Dominator to fire the P/40-K Bolt Pistol's explosive, heavy armor-penetrating warhead on a hotter gyrojet load:
- Damage: 500 (the Bolt Pistol's 325 impact + 175 explosive)
- Traits: Heavy Armor Penetrating · Explosive
- Speed: 380 m/s, up from 180 — a flatter, faster shot
- Range: 532 m cap (the stock round simply flew until it hit something; this one now despawns at 532m simulating the rocket motor running out of fuel)
- Arming distance: 12m OR 0.1m if set to unsafe mode — in normal mode when inside 12 meters the round hits without detonating so the blast doesn't catch you at point-blank range.
- Toggle on and off in the keybindings by setting a key via Bingus Vanilla Megapack's Mod Bindings Menu
- Persistent state to safe/unsafe arming distance mode
- HUD element reflecting safe/unsafe arming distance state
- Recoil: ~1.2× stock (new gyrojet propellant)
- Magazine: stock 15 rounds, unchanged
- Sound: optional WH40k: Space Marine 2 Heavy Bolt Rifle sound effect
Mod Bindings Menu dependency (for the arming toggle)
The arming-distance hotkey is the only thing that depends on Mod Bindings Menu. Everything else — warhead, speed, range, and recoil works with just Bingus Shared Loader.
What it is: Mod Bindings Menu (by CowboyBingus) adds a native MODS tab to the game's Options → Keybindings screen, next to General/Combat/Communication. Mods register hotkeys there so you set them through the game's own menu instead of editing config files.
How to set it up:
- Install/enable Mod Bindings Menu, deploy, restart the game.
- Go to Options → Keybindings → MODS tab.
- Find "Toggle arming distance" under the "Dominator Rechambered" section.
- Assign any key (keyboard, mouse, or controller all work).
- In-game, press it to flip arming between 12 meters (safe — the default) and 0.1 meters (live — the round detonates on contact, so watch your spacing).
- The binding starts unbound, so if the MODS tab shows the entry with no key, that's expected — just assign one.
Requires:
Known issue: The armory still lists the Dominator's stock traits (Medium Armor Penetrating, no Explosive). This is display-only. In combat, the rounds are Heavy Armor Penetrating and Explosive with 500 damage.
