I was thinking of replacing a weaver 4x i have on my savage 99 with a new weaver k4 and putting the older weaver on a 30/30 handi rifle , but then saw a millet buck silver 4x32 that was selling for $59.00 at midsouth shooters supply and i see they have lifetime guarantees are these good enough scopes to try out or should i stick with the weaver.
