I had the exact same problem and setup with the EGW mount. I ended up switching to Leupold mounts. Solved the problem easy as pie. Burris Signature Z rings are not nearly as commonly found as 5 years ago. Leupold mount and rings was an easy ebay purchase paid less for them then the Z Rings would have been. Mount a Swfa 10x40 SS. Now just settling the bugs outta the build. I have used both the SWFA and a Bushnell 3200 10x on this rifle both have been great scopes for the money. The Bushnell actually came off my rem700 308 contractor rifle.
