I have had two 20" rifle kits each with an A2 upper on order since the Black Friday sale last November. Per the retail sales department, you have every part in stock short of a couple small sub components of the A2 rear site. These parts have been out of stock for the last two years. I had asked retail sales if you would send the kits to me minus the A2 rear sites and just refund the difference. I was advised that this is not possible. Why not? The only option I was given was to switch to a flat top upper, which I do not want. I've been waiting for just shy of a year and with no ETA for the missing parts will have to wait much longer. Given this, I think a little flexibility is warranted.
By the way, the lady that I spoke with in Retail Sales is very nice and I don't want this message to reflect negatively upon her. She was pleasant and I think she did all she could do.
