The Aguila factory was originally established in 1961 and used by Remington. In 2011 a major upgrade to the production equipment and processes was begun which has reportedly made the Aquila ammunition plant one of the best and most modern in the world.
This is from the company website:
Aguila Ammunition is manufactured in Cuernavaca, Morelos, Mexico, by Industrias Tecnos, S.A. de C.V. In 2011, Tecnos partnered with Texas Armament & Technology (Tx-AT) to begin a facility-wide MODOP, or Modernization and Optimization, project to truly redefine ammunition production and reliability.
A February, 2016 article in American Rifleman gave the company good marks.
