Well, with the three month wait you just learned the cardinal rule of gun purchases....
ALWAYS BUY FROM A DEALER THAT HAS YOUR ITEM IN STOCK!
This goes triple for suppressors, by the way.
It's always better to buy from a dealer, even an out of state dealer, that has what you want in stock and have it transferred to your local dealer.
Glad you like the rifle though. LMT is the closest thing to a Colt you can buy, and the places where it falls short are insignificant (straight pins instead of taper, no park under the FSB).
