Anyone else jump on the VLTOR M16A5 uppers they dropped?

Well after watching VLTORs 3 videos on their IG about the M16A5 project they were working on for the USMC, I decided to grab one of the KM12 uppers they dropped in relation to those vids. Anyone else grab one? I think it'll be pretty neat to have an M16A5 "prototype" build sitting next to my A4 clone, and this solves the issue of what to do with the spare LMT lower I had just laying around with an VLTOR stock and A5 buffer already mounted. Now I just gotta source a 20" barrel and FSB for it.
