I can't compliment you ample concerning this gun. I've saved a picture of it on my desktop so I can "clone" it sometime. only one data issue, I picked up a handful of salty employed P&S M4 RAS's from Thoroughbred for $150 ea. yeah, not KAC, but ok for me. https://kac-carbine-rail52851.bloggerbags.com/34698824/rumored-buzz-on-kac-drop-in-rail
