I'm running a Burris AR332, 3X magnification (fixed) however I'm using the raised rail that is fixed to the side of the rifle. Works great minus the silly chin-weld haha! Looking at it, it would be in about the same spot in respect to how far forward it would mount, so I don't see you running into any issues with that one. It'd definitly help with the cheek weld issue too. There's a picture for reference below. The only catch with it is that you can't use the supplied sun-shade that comes with the Burris, it extends over the ejection port.
