Late to the thread, I'm no LT fanboy, Mark LaRue - love him or hate him, but I've been around long enough to recognize a smokin deal and painfully understand buy once, cry once. Skip the PSA upper. Cough up the coin and grab a Larue 18" assembled/test fired for $0 (through 12/26) Ultimate Upper Grendel. $891 FDE, $792 BLK. Then add a matching stripped billet lower for $200. $992 for a complete LT Grendel? Absolute no brainer. I'd bet $1.76 you'll have more than that into the PSA - options creep - by the time you get it where you want it. Jus my $0.02...
