Jim,
I just put a set of Williams on my Marlin 45-70. I do like scopes on my varmit guns, but on this gun I figured the longest shot might be 150 yards, and I can see that far. So, I went with the peep sights. I like open sights as well and I like these peeps. I think for the money you will not be disapointed.
Jut make sure you get to the range and practice with 'em.
