As with most optics I recommend, every U.S. Optics Riflescope are assembled in the U.S.A. with some of the glass and electronics coming from sources from other countries. Every U.S. Optics Riflescope is engineered to the standards we developed over our 28 year history, then hand assembled by skilled technicians before undergoing rigorous testing of the features by multiple technicians during their quality assurance process. If a U.S. Optics products proves to be deficient in function, quality, workmanship or material, U.S. Optics will repair or replace the product, regardless of transfer of ownership, for LIFE!
