For an inexpensive scope they are not too bad. I have had 1 on a 223 Tikka for many years, it was all I could afford at the time, the gun shoots so well I do not want to risk changing "ANYTHING"
I fellow I know had 1 on his 7 mag for a couple of years until he had the $$ for a Leupold, worker well for him.
They are not as crystal clear as some of the more expensive scope, but there are many worse scopes out there. :mrgreen:
