Its only a few dollars cheaper if anything , at that price its pretty much the lowest ,there just trying do get rid of over stock !
I can say they have a lot of bad reviews but simply go on live chat and ask if its in stock before ordering .
If you would use the not 922r compliant shotgun or rifle say defending your self that's where a prosecuting attorney or Feds would try and get you at.
But other than that who know's.
