If you use the DNZ mount, be sure and bed it to the receiver to aleve any stress that might be induced by receiver run-out.
Set a DNZ on an old Savage flat-back that seemed to fit very well.
Not saying it woulden't need to be bedded or checked, this one fit real well.
I was impressed with DNZ!
It hunts well also, smooth lines that seem to shed chafe rain and snow rather well and wipe clean.
I would put another DNZ on a rifle of mine.
