These were for a leupy mk4 hd 4.5-18 but will fit most scopes with similar dimensions. Front ring and ARD size is 2.405". Rear ring is 1.772" and rear cap is 1.67". These are made by hammy3dprints and are great quality. Only selling because I no longer have the mk4 and I ordered another set for the new scope.
Price is shipped. CONUS
