The local know it all

told me to just put on one of them
$9,00 dollar 4x15 Bushnell' s cause it would fit right on the 3/8 grooves
and it would do fine..
But I figured that if you put a scope on there like that you would
have to resight the scope all the time because when you shoot the
20ga it would shake the thing off center..
I would just put one of them scopes on there for the 22 but when
them squirrels start getting squirrelly

I' d like to be able to take
them with the 20.
