I am not a weight conscious shooter per say. Only recently have I built an AR that you would call light weight. My choice of parts was simply to see what could be achieved for a competition driven build to be light, accurate and soft shooting. My typical 3-gun AR was always around 9lbs with optic and mount. Never thought it was too heavy. Ive done lots of training and classes with a Carbine weighing 8lbs or so and never thought it too heavy, even carrying it all day. My lightweight build without optic came in at just over 5-1/2 lbs. with optic 7-1/2 lbs. (shed about 2lbs total) This is with a 18" barrel and full stock. Not a pistol with a short bbl. More importantly in my opinion is where the weight lies. The closer to the shooter the weight is the better. This one is superb.
I also started with a Wilson LW receiver set. Its not as light as some ultra light receiver sets, but for a billet set it was about the same as a forged set. Used a bunch of Titanium for the steel small parts, comp and gas block and went with a carbon fiber wrapped Proof Research barrel. 1/2" groups at 100yds are easy. Total cost was spendy, but not KAC spendy. It was a fun project.
