UPDATE 23 OCT 26:
Post-EAC rebuild. The loader is gone. This is a manual file swap.
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.
Additionally, all JAR-5 Dominator's have been been modified by armorers and are now proper select fires (semi, burst, full automatic).
Managed Democracy demands overwhelming firepower. This conversion ensures it.

Post-EAC stat plan json format. This is no longer a dl_bin swap mod so it doesn't require any merging with other dl_bin swap mods.

WHAT IT DOES
Rechambers the JAR-5 Dominator to the P/40-K Bolt Pistol's explosive warhead. Two ballistic profiles. Optional firing sound. The impact graphic is the pistol's, confirmed in mission on 23 Oct 2026. The magazine in the gun stays 15 rounds.
REGULAR
- Speed: 380 m/s, up from 180.
- Range: 532 m. The rocket motor burns out and the round despawns.
- Arming distance: 12 m.
- Recoil: about 1.2x stock.
- Spare magazines: 6.
- Blast: the bolt pistol's. Full damage inside 1 m, falls off through 6 m, nothing at 7 m.
REALISTIC
- Speed: 450 m/s. The game stores one speed, so this is the speed after the motor finishes, not the crawl at the muzzle.
- Range: 360 m.
- Arming distance: 15 m.
- Recoil: 0.60x stock. Most of the push happens after the round has left.
- Spare magazines: 4. Fifteen rounds are still in the gun.
- Spread: +1 on both cones.
- Blast: a private copy. Full damage inside 1 m, nothing past 2 m. The bolt pistol keeps its own wider blast.
- The dl_bin file swap versions will load into any mod manager. They will conflict with any other dl_bin swap mods and you will need a mod merger to reconcile.
- The statplan versions are compatible with Ordnance and require only Ordnance.
FIRING SOUND
Pick one, or leave it stock. Darktide, Space Marine II, Boltgun, or Necromunda. The stat swap and the sound are independent. Install a profile, then a sound, or use the sound alone.
KNOWN ISSUES
- The armory still shows the stock Medium text. The Heavy / Explosive tags are not on the card.
- There is no full-auto, and no SAFE/UNSAFE wheel. Those belonged to the old loader build. They are not in this one.
- The Space Marine 2 audio file is 3 dB too loud.
