They e-mailed a shipping label and I was able to send it in the same day. I used the original box, just wrapped with brown shipping paper. It was in late July. You do need to have an adult sign for it when they send it back - doesn't have to be you...
I had feeding issues with mine when I first got it (July 2018). I sent it back and they fixed it - works fine now with all types of ammo I have tried from hunting rounds to mil-spec.. It took about 4 weeks plus shipping time.
