For me, I might have reached that point with the Scout Rifle concept. I find that it has more or less become obsolete as a general purpose rifle has taken it's place and I think this new Ruger SFAR which comes in under 7 pounds as a semi auto rifle might just do it. 

Has anyone else "moved on"?

I am tempted to sell off the 6.5 Grendel rifle and associated ammo. Open to ideas.
