As you can see in the pics, this is a rail from DIP, model number 19079, that fits a CZ 457. It is a 25 MOA rail, which gets you well past 300 yards with the right scope, but I switched to 40 MOA to get way…way out there. It was purchased along with several others as a “blem,” but if there’s a scuff anywhere I can’t find it. The edges in the pic look like maybe the cerakote is warn through, but it’s just the light. This one is brand new, I only took it out of the bag inside the package to take pics. The other “blems” have been put on 457’s and work fine, so not sure what made them blemished to begin with, other than I know DIP has VERY high standards. I’ll sell this one for $30 shipped, but will also be posting some slightly used ones of these for $25 shipped if you’d rather save a few bucks. Thanks for looking.
