@a6m5 the setup you have on your M&P15 pretty sweet. I like the fact that you can go from mid-range to CQB without removing your hands from your firearm. Being that the BDC reticle on your Burris is setup for .223/5.56, I'd patiently wait for another tube style red dot with a BDC for .300BLK/7.62x39. There is always the Trijicon ACOG but it isn't cheap.
Theoretically you could do that. But with the scope that close to your eye, you're going to get first hand experience of "scope bite"
. I'm somewhat embarrased to admit it but I have personally experienced scope bite on another rifle and I was grateful for the fact that I was wearing eye pro. At this point there are a few things wrong: scope is mounted improperly, your vision has diminished or you simply have the wrong scope for the wrong application.
