[QUOTE="Welderboy250, post: 811136, member: 67711"] I'm new here and I know this is not the optics forum but I believe the problem lies with the receiver so ill post here, please move if it is the wrong place to post. I found this ruger heavy brl .204 on gunbroker for a friend. It had a horrible scope mounted. Didn't know at the time someone had done what seems to be a real hack job mounting. There was what appears to be a rectangular section of a plastic water bottle in the front ring under the scope tube. I observed this was necessary for the bell to clear the barrel without taller rings. Removed the plastic and laid the new scope in and did a quick rock test to see how bad things might be for alignment. IT WAS HORRIBLE! Pressing down over the front ring lifted the scope off the rear slightly, pressure over the rear one lifted it off the front one a good eighth inch! Some careful study eventually yielded the conclusion that the integral ring mounts are not machined parallel. There is no detectable problem with the rings, it is all in the receiver. What should be done with this thing? [/QUOTE]
