Considering most instructions I've ever cared to read have indicated 20 in/lbs, I'd say that I woudn't be too worried about crushing any tubes until you are well
past 15 in/lbs.
But scope ring toque values are not on topic what-so-ever.
My dad's lightweight 7mm Rem Mag has had the Viper HS 4-16x44 (similar internals to the PST) on it for a full year now that has seen 100+ rounds without a hiccup. The turrets track well and the zero doesn't wander.
At the shop where I work we sell a whack of Vortex and the only ones I've ever seen come back in (occasionally) where the Crossfires and Diamondbacks. Never seen a Viper come back yet. I'm sure it will happen one day but it's been at least 3 years so far without a hitch.
My next scope will probably be a PST 6-24 FFP of some variety.
