I got one of the 750ml versions a couple weeks ago from AGG.
Advertised weight is 3.36 oz. Mine weighed in at 3.3oz.
The silicone handle covers can be removed and put back on with little effort. They weigh in at 0.1 oz.
Don't know about the fuel canisters. The published dimensions are 3.9" wide x 4.36 " tall.
The lid is very nice. It press fit snaps into place for draining pasta so you don't have to have your hand on the lid while draining (no steam burns).
The lid knob is riveted onto the pot. If you want to replace it with something lighter, you will have to drill out the rivet first. But since it requires 2 hands and a firm grip to remove the lid when it is locked onto the pot, I don't think I am going to mess with this.
I was a little concerned at first that it required so much effort to take the lid off the pot when it was locked on there. This could make for a dangerous situation if you were trying to remove the lid with boiling water in the pot, possibly causing splashing and all that. But the lid can be sat securely on the pot, without locking it into place. I think the only times I would lock the lid into place is when I was draining pasta or when I have the pot packed away in my pack.
One of the reasons I bought this pot was that it was one of the lightest pots I could find that would fit one of those fancy new Bushcooker LT1 woodburning stoves inside.

5.8 oz for stove and pot…. Sure you can go lighter with a Heineken can and a alky stove, but then you have to carry fuel…
BTW you could go lighter with an 850ml pot from Mountain Laurel Designs (3.15 oz). But I really liked the snap on lid….
