As a result of this, MUSA developed the M32A1 to meet the requirements of the solicitation… Milkor USA, Inc., is 100% USA owned company with no ties to any South African company. Quality is the core principal of MUSA’s MSGL product line. As a result, MUSA developed a relationship with Abrams Airborne Manufacturing, Inc. (AAMI), a company based in Tucson, Arizona. AAMI is an AS9100 Rev D and ISO 9001:2015 certified manufacturing facility that can produce MUSA’s MSGLs to the superior quality that MUSA demands in its weapon systems.
