OP did indicate he wanted a "Gucci" AR. This is not the same as stating he wants an accurate AR, thus your suggestion would be spot on. I know MSTN has been around a long time, and I have heard that he builds accurate rifles, but I will never get on board with CF barrels. I have known so many people who have had them on their rifles only to turn around and ditch them. The primary reason amongst a few others being, they just can't maintain accuracy over sustained strings of fire.
OP - if I were to ask a clarifying question, such as, are you wanting a quality "precision" AR, or just something that looks cool? Also, if
@bigjake83 is offering to put a rig together for you, I would just get his address, order the list of shit he provided you, have it all shipped to him, and wait for it to arrive.
If you want a "factory built" rig, just get the JP. I've got a couple KAC's and they are great rifles, they just aren't worth what they are going for in today's market (IMO, of course). I've read a lot of good things about LMT, but I have no personal experience with them.
