The kifaru gunbearer is a good idea for hands-free carry, but it doesn't work well for at-the-ready carry.
I substituted a quick-release webbing buckle at the top anchor, just pinch the buckle tabs and the gun is free, ready to pull up.
I use a stiffer belt-loop (nail) bag for the butt end, because it doesn't collapse around the butt and resist it being pulled out. Rifle comes in and out of the stiff bag very easily for quick deploy.
It's the best "at the ready" system out there imo
