i just put one on my .204 handi rifle , so far I like it . For $70 its hard to beat a scope with flip up caps, rings and 16 power and if you would have problems you can take it back to Wal mart
my buddy has one on a 270wsm that he bought at W.M. I think it is 4-16x40 with mildot that lights up, he is very pleased with it for the price he paid.
