There is a company in Oklahoma that repairs old Redfield scopes made in the USA (Denver) prior to the sale of the Redfield company. However since your scope is a cheap model it is probably not worth the cost of repair ~$50. Their address is: Iron Sight Corp.,3324 S. 76th W. Ave.,Tulsa OK 74107 phone: 918-445-2296. They did a good job repairing an old quality 2-7x Redfield for me, but if my cheap Redfield lo pro 3-9x broke, I would throw it away as the optics are not that good.
