[1] The company has been headquartered in Marikina, Philippines since 1958[2] and represented in the United States by its subsidiary Armscor International, Inc., located in Pahrump, Nevada with facilities in Stevensville, Montana.

[4] The company was bought by the Tuason family in 1941 and began making firearms through the present corporation in 1952, being renamed Squires Bingham Manufacturing, Inc. in the same year.

Armscor is an ISO 9001 certified compliant company which manufactures weapons using CNC (Computer Numerical Control) equipment.
