Working Paper – Firearms Marking with Laser Engraving: Technical Insights and Recommendations

Marking is a critical element in arms control, aiding with effective stockpile management, preventing the diversion of firearms into illicit markets, countering illicit trafficking and ensuring the traceability of firearms in criminal investigations.

This paper explores the use of laser engraving technology for firearm marking in accordance with international and regional instruments, including the Programme of Action on Small Arms and Light Weapons, the International Tracing Instrument, the Firearms Protocol, and the Inter American Convention against Illicit Trafficking and Manufacturing of Firearms, Ammunition, Explosives and other Related Materials, as well as best practices for firearms marking outlined in module 05.30 on marking and record-keeping of the Modular Small Arms Control Compendium (MOSAIC).

The paper presents findings of experimental research aimed at identifying the optimal applications of laser engraving for marking firearms to prevent, to the extent possible, their obliteration, and to ensure, as far as technically possible, their recoverability.
