Tried working with Quantico Tactical on their M&P15. I highly recommend staying away from them.
I originally e-mailed them Sunday, and received a response Monday morning to call that day to secure a rifle. I asked about the M&P 15 M4 Clone with carry handle. I think it was listed on the website at around $780 after mail-in rebate. I knew they were on back order, but I asked if I could order and pay for one now so I'd have a dated receipt to get the $100 rebate from S&W.
Monday I tried calling, but the store was closed. So I e-mailed Lisa (head of govt sales) again and left a voicemail.
Last night she e-mailed me and apologized for missing me (they closed early Monday) and said to call today. After several attempts, I finally got in touch with her.
Apparently the prices of all the M&P had gone up nearly $100 ($829) since the weekend. And despite saying it would be no problem, she would not charge me to generate a receipt until the rifle comes in and ships (one-two weeks). So the price is actually $929.
My buddy and I were going to buy two rifles, so later today I called back and asked if she'd honor the original price for both of us, but she declined. I understand demand right now, but if you're going to market to military and act like you're helping everyone out, it's poor form to raise the price over the course of a couple of days. You're not doing me a favor buy selling me something, so don't act like it. Especially when no manufacturer has raised any prices. (Her stance was, "Well it's still well under MSRP").
Anyway, recommend avoiding that place for firearms purchases.
