  • These are assembled by me by hand as well as transported back and forth from the range from test firing. Becuase of the handling of the uppers there will be some very minor cosmetic blemishes. If you are looking for a showroom finish, please look elsewhere. I expect my uppers to be used harshly and to handle the abuse. Any issues with function will be immediately addressed and remedied to the satasfaction of the customer.
