Castor, thanks for 800 #. I called Weaver at that number and they gave me the # of the Weaver repair station in El Paso. 915-593-1005. Address is 1121 Larry Mahan Dr., El Paso, 79925.
The lady at Weaver said they handle all the repairs on Weaver scopes. Mine's an oldie-but-goldie V4.5.
Best of luck. L.W.
