With your .223, recoil is not really an issue regarding the 'shock proof' claim...Normal and reasonable care will provide years of good service...However, unless you get into the high dollar, combat ready optics, most scopes will survive an occasional drop or hard knock, but repeated such blows can break loose the reticle filaments...
"Fog proof", again, is sometimes a relative term...Extreme and rapid temperature changes can produce negative results...For that reason, many hunters will store their rifles/scopes in their vehicle overnight for the next mornings outing, rather than taking it from a relatively warm house into freezing or sub-freezing temperatures...The short term heat while driving the vehicle usually won't permeate the scope enough to cause a problem..
