I'm fixing to get me an RRA 6.8 upper to put on my RRA CAR2, anybody out there done that and what do yall think about it?

I just got through building a custom 6.8 using a ko-tonics barrel and Sun Devil billet upper/lower set. It turned out nice. I'll get pics up eventually.
Anyway, a complete 6.8 upper will swap on with no other mods except the magazine. Go for it! (The ammo is EXPENSIVE though...)
