There’s a bit more to it. Certain models will be lighter than others due to size. An HTG will be significantly lighter than an A4 regardless of fill choice.
Some models also benefit more from the carbon fibre and fill than others. Again, an HTG can be made extremely light. Whereas, there are typically only a few ounces difference in a standard fill A1-3 and an Edge model.
Consider also that light fills can be a waste of money. For example, McMillan uses a heavier fill in areas with flush cups or rails. So if you want a front rail and six flush cups, better to go standard than pay for Edge and have half the fill heavy anyway....
I'll probably get called a heretic for this, but I like the HS precision Remington LTR stock better than any for a light weight stock, and I've had a lot of nice stocks. After glass bedding, installing Karsten cheek piece and replacing the bottom metal with badger M5, it is tough to beat.
I bought a fully-adjustable HTG with the intention of replacing the LTR stock, but I just can't do it. If I were going to build another light weight bolt I'd look for another LTR take-off.
I'll sell you the HTG for what I paid for it if you like....

I'm sure that's true, but it's not just the weight for me. The LTR stock is also considerably shorter and handier, and not to mention, a good $600 cheaper. I was more surprised than anyone when I came to this conclusion. I never realized how much I liked this stock until I took it off and tried something else.
Don't get me wrong, I love McMillan's stocks and have had quite a few, as well as manners, AI and other custom and factory stocks. If I'm being honest with myself, I just like the LTR the best for a lightweight rifle.

I love the A3. If i was trying to save a few more ounces i would go with the A3 Sporter with the Edge Tech. The grip on the A series for me is perfect. Here is a pic of the A3 Sporter, it's not pictured on their website but they make it.
