LaRue 6.5 Grendel Rifles

[Mrvmax17]

New guy here on the forum (but been around for a while and am on numerous other forums). I ordered the upper kit and stripped lower on the weekend of the 16th, I'm in Texas and I thought I would get my stuff this weekend to assemble (I have a hunting trip coming up and I want to take this rifle). I could not pass this deal and although I didn't want yet another different caliber to load for I did it anyway. I have a new night vision scope I plan on using on this rifle. I called LaRue the 20th and asked when it would ship, they stated they were out of boxes and buffers and it would be the end of next week before it shipped. I really want to use this on my hunting trip so I called them back and asked if I can pay extra and have them ship what they have right now and ship the buffer later. Their customer service dude said if they did that there was no way to track the buffer and I would never get it. I said no problem, I do not need it anyway just ship my stuff (I explained to him why). He said it wouldn't matter, it would still be the end of next week before it ships.
I am actually a part time FFL so I have received a few of their complete rifles over the years but I have never bought from the before. I can say that so far their customer service is lacking. First, how do you run out of boxes? Second, what is so hard about making a new tracking number to track a buffer? What is so hard about not shipping the buffer and packing up what they have and shipping? I spoke with two different customer service reps and it sounds like they just do not care to do anything to help me out. It is not that difficult to leave out the buffer and ship it to me. I am not impressed thus far, I hope this is the end of the disappointment with them.
