I have been eyeing the vortex scopes, and the viper line is out of my budget for a while

I figured i would get a crossfire (6-24x50 specifically), people seem to generally have high praise for them, but i have seen some remarks they are not for high recoil rifles ?

This would be going on a 308, I would like to get the 30MM tube, but due to needy little ankle biters, may end up with a 1" tube for now.

Should i be concerned with crossfire scopes rattling loose ? I generally load to the mid range loads, currently I am workikng on a 168gr load with varget.

Thanks
