Too tight / poor qc? - Anarchy Outdoors Bolt Shroud Replacement, Ruger American Rifle

This shroud was too tight and difficult to install (and subsequently remove). It seems as if there wasn't enough material removed during machining and the interior diameter was too small. Once installed and the bolt placed back in the rifle, I could barely work the bolt. I removed this shroud and reinstalled the cheap plastic shroud --- voila --- worked fine.
