oh man sorry for the frustration, Sadly QC is just not what it used to be... Look at vehicles these days they are mostly junk!
Everytime I turn around I have another recall.
I also in the last few years have purchased 2- ($6,000 ish) Rifles and both had minor Issues. (parts, screws,cosmetics)
I reached out to both of the the brands Direcetly, and they were able to help me out either Locally or
In one case one sent me extra screws.
I like others would suggest taking it to a local smith, or sending it to a good smith. Cut the loses, and enjoy the rifle, Sadly
I get if this whole ordeal taints the rifle for you.
