Whatever the rifle I want to carry weighs.
Here's my "lightweight" calling rig:
I built this rifle as a lightweight alternative to my other calling rifles, then wanted more and more options, and started adding to it. Empty, it was just under 7lbs originally, compared to 12.5lbs for my 24" heavy barrel Ar or 12.9lbs for my wife's Savage 12. Then over a few years time I added the scope, foregrip, and bipod, pushed it up to 10.3lbs. Still 2lbs lighter than the other ones, but quite a bit heavier than my rimfire calling rigs.
Sure, it's nicer carrying a 7lb bolt gun, but by the time I strap on a scope and bipod, I'm in the 8-9lb running weight anyway.
But then again, I'm young enough that carrying a little extra rifle doesn't hurt my feelings. I'm not suggesting anyone carry a 17lb bench rig, but I won't complain for anything in the 8-13lb range.
