Two thumbs up here for Aero mounts. Great way to save weight and they are a solid mount. Another option to cut a bit of weight would be a ti gas block.
I know the barrel is a big piece of the weight but it is a tack driver and I'm hesitant to "fix" it. I've just got a regular M4 buffer tube/stock on there. Off to google lightweight stocks...Can you loose some weight with a different stock?
I had a barrel recontoured to shave weight with no accuracy loss.
Awesome, thanks.Except for the barrel, you cant really save a lot of weight in any one component, its a little here and a little there, but it adds up. Take a look at breastroker's lightweight build thread:

in lightweight hiking we say grams add up to ounces and ounces add up to pounds...Awesome, thanks.
I see what you mean about a little here & there. This would save me ~2.5 oz but I have a hard time spending $50 to save <3 oz.
I'm trying to not let this turn into a bigger project but I'm going to copy your list format:I built a lightweight 6.8 mainly for pushing woods in WI this past year. Thread at:

I run the 16" Wilson Combat Lightweight Tactical Hunter barrel on my 6.8 and it is amazing how much weight it saves over my standard .223 heavy contour barrels. Plus, the barrel is a tack driver and managed to put down two whitetail bucks this past season.
Since you swapped hand guards, I would recommend the strike industries viper stock as a way to shave some weight for your next step. Since my original post going over the components of my build, I have swapped out the Magpul stock for the strike industries viper and it feels considerably lighter in my hands as compared to the Magpul.
As other mentioned above, the Aero mount is a great way to shave weight and I am also considering swapping out my Burris PEPR for one for next season.
The only other area that you could potentially really shave considerable weight would be a lighter scope, but this is easier said than done depending on the type of optic and level of magnification variability you want.
I look forward to seeing how your weight shaving progresses.
