The other thing I noticed they are doing differently than other 80% lowers that have an ATF determination letter is marking the position of the selector and hammer and trigger pins... to your point, this makes it too easy- you don't need knowledge or a jig to complete it.
Just pointing out things that are different than the EP Lowers vs other 80% lowers I've seen.
Moral of the story- get a determination letter before selling.
