Burris x-bolt bases - Burris Trumount Universal Rifle Scope Two Piece Base

I ordered these for a project rifle, (not an x-bolt) but did not use them due to a change in my design. Not only was Optics Planet the cheapest, including private sellers on eBay, but was about the only retailer that still lists them. I did return them and Optics Planet made the process painless. Normally I would not return one small part, but OpticsPlanet only had one set in stock when I ordered, since I can’t return the two sets I bought for higher prices from two separate eBay privateers, I didn’t need 3 sets hanging on the workbench.
