Factory rings will be fine, the screws are a little soft, I replaced them with screws from Ace Hardware, total cost of around $2.00. I have had the factory rings on a 308 Win for around 5 years with no issues.
If it is a T3X I have read that they do not come with ringss, in that case you could post a WTB and find some T3 factory rings or go with aftermarket ones.

What fits in the factory rings?
