Nothing will wreck and aluminum part quicker than over torqueing.
Yes, aluminium castings in particular don't have much ductility, so overdo the torque and you are apt to get a fracture that looks just like the one pictured earlier in this thread.
This. I've use the LWTs for a very long time and have never had an issue, apart from one shearing off a base screw, but that was due the rifle taking a very bad fall. It certainly wasn't the fault of the rings, which are still doing their job on that particular rifle. And all the kudos here on Talley's customer service are well-earned, in my experience.
