2nd pair in a row that have failed miserably. First pair was so out of spec a 30mm Zeiss scope would not even turn in the rings . I lapped them and still way way too tight. I returned them and they sent them right back saying they were to spec.They thought my scope was out of spec . grin They make a nice paperweight.

A year later bought mounts for a Weatherby ULW(Game Reapers) ...Half the mount is finished semi gloss the other half is really matte. At that point I should have saved my time and just prepped them for return. I did not do that and mounted them on the rifle without incident until I attempted to put the rear ring cap on and found out it was not threaded all the way . I have a tap at home but will be damned if I am going to fix this POS. It is going back.

I am not even going to attempt to contact the manufacturer since they suck at what they do.
