yea, but a sample of one doesn't bug me much. somebody on that thread talked about thinking the concave radius on the base was too small so when the base was tightened to the receiver, it had to spread open a little. kinda my thoughts too, but without knowing for sure it wasn't operator error or a incorrect base (packaged wrong perhaps), I'll carry on knowing they have worked for me for a long time.
the Burris DD bases may be an option for those with nagging doubts from the leupold thread. they look solid, and my M70 .375 AI has a fairly heavy scope in a set of those.
