Well, if it's any consolation, I had to send my new 1894CB back for a warranty repair.
I got it back in less than 30 days and it is perfect.
I am not excusing Marlin. And I know that you feel bad. But give customer service a chance to do right by you.
They make the return process very easy on their website. You will get a return authorization number and a shipping label in seconds.
Yeah, giving up your new rifle for a while sucks but if you return it they may track down the assembly people involved and provide some remedial training. Hopefully enough returns will lead to an overall improvement.
I'm convinced that the demand is so high that they are cranking them out. A victim of their own success so to speak.
I recently returned a Henry 357 lever for glaring tooling marks all down the bore. It happens.
