I wouldnt worry to much about it. It isnt like your going out on a once in a lifetime hunt with an air gun and vortex has one of the best warantees in the bussiness. I here storys all the time about air guns tearing up scopes but ive got a piston gun here that has had i dont know how many pds of pellets through it and it wears a cheap 4x bushnell banner and its never given me a lick of problems.
