Yes, but Hesse/Vulcan/Blackthorn pieces have been known to be out of spec and they do not stand behind their product. Worse, their receivers have been known to fail within a couple hundred rounds. Improper heat treatment, poor machining, etc., is the order of the day.
There are other kits and makers out there at similar price points that aren’t as crap or dangerous as H/V/B.
If I only had $600 to get set up I'd get an AK. If I only had $150 i'd get an AR lower before the ban, followed by a cheap kit then upgrade a apiece at a time as I could afford.
