GUN4IR (pronounced “Gun For I-R”) is a DIY light gun system created by French developer Jean-Baptiste "JayBee" Bongrand. Unlike many commercial light guns, GUN4IR is not a standalone product — it is a framework that allows you to build your own high-performance light gun by sourcing components and assembling them in a casing of your choice.

The year 2021 marked a major transition point for the GUN4IR project. Prior to this era, early iterations of the code and fragmented user guides floated around open-source repositories like GitHub.

The DIY lightgun community changed forever with the introduction of the GUN4IR system. Developed by Jean-Baptiste Bongrand (known community-wide as JayBee), this project brought arcade-accurate, zero-lag lightgun tracking to modern LED and OLED screens. [ Your PC ] ---> Reads "license" file

Revenue from these $20–$30 USD licenses directly funds continuous development, such as the introduction of unified firmware and improved IR detection algorithms. Integration:

Expanded the library of undocumented serial commands, allowing advanced users to modify gun aspects through code. Licensing & Delivery Specifics
