RWS droop mounts too long!

I just found out that my three new RWS droop mounts scope rings are too long, by about half an inch, for my three Hawke Vantage scopes. Guess I could cut out the middle section and make it a shorter two piece mount. I just reinstalled my old one pice mount and see if the gives out as centered the gun was shooting about 4 inches low at about 12yards. Disappointed fur sure. Three boats anchors with zero use. Just wanted you to know about the problem so you can avoid trying it. Charles
