Quality control? You mean they have a QC department. The end user is their QC department. I stopped buying Ruger products sight unseen. I lost count but I think I had to send the last six Rutgers I bought back to factory to be finished. They should have never been allowed out the door.
I cant say I blame you. I wont buy a pieced together AR regardless of brand. I wont buy any AR at this point because I have to many as it is.
