Three years later, the integrated SAA manufacturing began, with all components - case, primer, propellant powder, and bullet assembled into a complete cartridge.

[7] Republic Act 7898 likewise provides for the modernization of the Government Arsenal for the development of production capabilities to enhance self-sufficiency in defense requirements.

"[4] As part of the modernization effort, the arsenal, through the Department of National Defense, issued an invitation to bid for a Multi-Station Bullet Assembly Machine for 5.56mm M193/M855 in August 2009.

[10] On April 5, 2019, the arsenal broke ground for two major production facilities under co-production agreements with South Korean firms: a force protection equipment manufacturing plant in partnership with Samyang Comtech and a 5.56mm magazine manufacturing plant in partnership with Buhueng Precision.

In 2011, a new standard coding system was adopted by the arsenal following its formulation and final approval in October of the previous year.

The revised system uses simplified alphanumeric designations that make reference to the ammunition's caliber and type for ease of identification while avoiding unnecessary complications caused by the use of mixed English & SI units and designations based on different foreign code systems.
