Why should we Free BSD?
Just saying switching to an HBAR on a pre 10/1 build is legal as is switching back. The barrel may have been test fired to check headspace also.
As for the rest, thats just shitty quality.
If you are test firing it, you don't make markings on the barrel nut and extension that appear as if it was mounted to an upper. This thing has some serious scraping done of the phosphating on the barrel extension, and the barrel nut looked like somebody that didn't know what they were doing mounted it on an upper. It is almost as if somebody mounted it, decided they didn't like it, sent it back, and they shipped it out, claiming it was new.
