Solid but be careful - Troy Safety Selector Assembly, Direct Thread, Ambi, Semi Auto

Is there a risk of stripping? Yes. Can you avoid it? Yes. You can try removing some of the red loctite to make it easier to turn in, or just use a wrench set that has one of those large plastic turning handles to get the best purchase on the screw. Feel is quite smooth, though that may be partially thanks to the ballpoint roller detent I used from a triggertech safety paired with this lever.
