With the AimPoint gooseneck mount, the QRP is probably your best bet, as it will co-witness perfectly with the irons with that setup. For a flattop, I would recommend a Swan Sleeve and A.R.M.S. CompII mount, but for the application you specify, the QRP is, in my opinion, the way to go. This is precisely the setup I had before switching to an A3 upper. I gave my old A2 upper to a buddy, and he is building a rifle with it. He already has a red-dot installed on it using my old gooseneck and QRP. My only complaints about the setup is that the QRP does not hold zero as well as some other mounts out there (A.R.M.S. specifically) and the gooseneck mount restricts the view through the carry handle sight channel when using the irons. Other than that, it's a very functional setup.
