ANYTHING less than a 16" barrel is considered a NFA / SBR or Pistol Upper. DEPENDING what your plans are. I have X SBR's and X pistol lowers (already set up as) How many uppers and what barrel length i have is irrelevant. As anyone, outside a Vague legal interpretation would agree.
AS for "chucking it on the lower" ONLY if you purchased the lower as OTHER or PISTOL.
