We are extremely confident in our rifles and all come with a lifetime warranty on any defect/quality control issues. Our rifles are hand built one at a time and put through reliability/accuracy testing before ever leaving the shop. Although every part is carefully inspected these rifles are built from de-milled military rifles most made 30-60 years ago. That being said if one of these parts ever breaks/wears out(highly unlikely) we will complete all necessary repairs at a discounted rate.
