The rifle my LW's broke on wasn't shot much, as mentioned 84L Classic. With Leupold 2.5-8x. Not much use or scope weight.
I really don't think it is a matter of use, and maybe scope mass, but the strain on the aluminium being too much. Also, mine were torqued correctly with a torque wrench.
So many people on here have had issues that I think I won't be going forward with them, so much of a problem if they go tits up on a hunt.
