How does everyone carry their rifle while rucking?

I use a AGC bino harness and I found, recently while out rabbit hunting, that I dislike having to have my rifle strapped to the side of my bag. It was hard to get on and off, I found I had had to take the bag completely off to get my rifle into my hands.

What is everyone using? I am planning on buying a new (to me) hunting bag, either EMG or Kifaru. Are guys just running a quality gun sling? Are you using the gun bearer (does a bino harness get in the way)? Or are you simply using the compression straps on the side of you bag to keep it fixed to your pack?

Thanks everyone!
