Zhu-Rong v418, developed under the codename ZRIN by L.O.B. Enterprises, is a man-portable incendiary weapon built on the basis of a standard Shanxi Type 17 sidearm. The key component is an acumist barrel, replacing the standard one. Upon pressing the trigger, a standard 10mm round is fired and partially liquefied by the barrel coating. Upon impact, it liquifies entirely and delivers incendiary damage. Retardant jacketing and internal heat diffusers protect the operator's hands and fingers from injury. These properties give it superior accuracy and performance over other ZRIN prototypes, enough to qualify it as a production candidate.
Earlier prototypes were much less successful. ZRIN-363 weighed 118.3 kg and emitted dangerous fumes. The next model, ZRIN-375, used a proprietary ammunition type based on the 10mm round. However, the caplet with amalgamating agents, while creating spectacular firebursts and shrapnel projection in line with the project requirements, it proved excessively sensitive: Ammunition could explode due to vibration produced by simply walking. The penultimate functional prototype, ZRIN-401, rectified all of these problems, by using standard 10mm ammunition and using an acumist barrel to superheat the projectiles, but the lack of heat protection meant using it for prolonged periods of time was hazardous to the operator.
The Zhu-Rong pistol does the same low amount of damage as the regular Chinese pistol but has a slower rate of fire. Although its damage might not be quite on a par with other more powerful sidearms, the Zhu-Rong v418 has incendiary properties, dealing some fire damage upon hitting a target. It has the longest range of all incendiary weapons, aside from the heavy incinerator. Enemies killed with this pistol will often explode into dozens of flaming chunks.
The Zhu-Rong is able to fire 1659 rounds (about 166 magazines) before breaking.
The Zhu-Rong pistol can only be found in L.O.B. Enterprises. It is found behind a Very Hard locked door (requires a Lockpick skill of 100) in the CEO's office in the case on his desk. The key for the case is inside his desk. It is also possible to reach the case by working the Lone Wanderer's way around the edge of the destroyed top floor until they are on the other side of the locked door.
Behind the scenes
The name is a reference to the ancient Chinese god of fire, Zhu Rong.
PCPlayStation 3Xbox 360 There is a bug where only the first shot from the pistol in V.A.T.S. does any damage. Once an enemy is on fire, additional hits from the Zhu-Rong seem to have no effect.
↑Lab Report: Prototype ZRIN-418: "Lab Report: Prototype ZRIN-418 Prototype refines acumist barrel experiments by addition of retardant jacketing, as well as internal heat diffusers. Rate of fire diminished from un-modified version of weapon. Conventional 10mm ammunition does not fully liquefy until impact, giving the 418 exceptional accuracy compared to earlier prototypes. Live-fire tests report no major casualties. Recommend ZRIN-418 as production candidate."
↑Lab Report: Prototype ZRIN-363: "Lab Report: Prototype ZRIN-363 Experimental prototype makes extensive use of hardware common to liquid ammunition flame projection weapons. While initial test results were impressive, extreme weight of unit (118.3kg) and fume inhalation rendered most test subjects incapable of firing the unit or remaining conscious under typical field conditions."
↑Lab Report: Prototype ZRIN-375: "Lab Report: Prototype ZRIN-375 Prototype introduces proprietary ammunition type. Conventional 10mm shells house a caplet containing amalgamating agents. When the caplet was broken in lab tests, localized fireburst and shrapnel projection met requirements for project. However, in field tests amalgam caplet ammunition proved too fragile, and several detonated from excessive vibration or walk speed."
↑Lab Report: Prototype ZRIN-401: "Lab Report: Prototype ZRIN-401 Prototype attempts to refine results of acumist coating within weapon barrel. Initial tests showed promise. As predicted, delivery friction super-heats projectile as it is delivered from the weapon, and conventional 10mm ammunition can be used. However; during live-fire testing, subjects firing the weapon in rapid succession suffered severe burns to the fingers and palm."
