not John, but IME, no.
In addition two those two new FX-IIs defective right out of the box, I can think of at least one more FX-II (With M1 turrets), one old M8, and a fixed pistol scope I'm not currently remembering the details of at the moment that went belly up.
the pistol scope was on a .454
the FXs were on : .280,30-06, two 338s, and a .375
on the flipside, I have an older Vari-X II 1x4x20 that's been on a .375 for about 12 years or more and probably has over 2000 rounds under it's belt without a hitch.
you pays your money and you takes your chances....
