Looking to put together a nice replica M16A4 upper. I would like it to be correct as possible but I can live with the m4 feedramps if I had to as it will see full-auto use. Any good suggestions on venders for....

A3 upper with RAS markings (M4 or W/O)
20" Gov't profile 1/7 Barrel
KAC M5

I see PKF has Sabre Defence 20" Gov't contour barrel / KAC M5 / A4 complete upper. I really have no knowledge on the SD barrels are they accurate / quality?

Thanks for any help or insight,
