Project Featherweight

[SC-Texas]

I am building a lightweight for my wife:
1. CMMG govt profile 11.5"barrel
2. Clark custom carbon fiber handguard - 6oz
3. ACE ultra light stock
4. Looking for a no F/A upper receiver

[Robb Jensen]

Perhaps I have missed a "chart of lightness" has anyone produced one of these yet?

Is a moe grip lighter than an A1?
The new mini Troy grip?
Are HK mp7 sights the lightest?
Weights of flashhiders?
The 9mm RRA upper vs standard?

I can see a middy using a light buffer and carrier... Maybe a new project aloft

I'm not good at making Charts maybe Rob_S will make one. I'm more than willing to help supply the data as I have a lot of access to a lot of stuff to weigh.

there used to be a Maryland AR shooters MSN group that had a huge spreadsheet of weights of just about everything. I think the group went away and therefore who knows what happened to the chart. I think I saved it a couple of times so if I can find it I'll put it in google docs, share it, and we can start adding to it. Might take me a little bit to find.

I found a few two year old archived versions of the Maryland AR Shooters (once excellent) site.

Both take a long, long time to load and navigate. The second appears to be slightly faster, but the colors make reading menus a PIA. If I can find the chart there, I'll post it.

ETA: I'm thinking of dedicating a computer to just navigating this stuff. I've yet to get beyond the first page. But, one poster on another site (not TOS) stated they got some info off the archive a few weeks ago, so ...)

Bad news: the link to that chart is DEAD. The reference notes that it was member-only accessible, and that may explain it.

rob_s: no pressure.

I weighed a bunch of stuff today. I'll get it posted up tonight and then Rob_S can use it in a parts weight chart.

Once I find, and convert, the Maryland chart I'll start a new thread where we can compile info into one place.

Wold be good to get people to post pictures of the items on the scale as it alleviates any confusion (was that with the screws or without, what xyz did you have inserted, etc.).

I was a member, which is how I got the chart the first time, but I think the group is defunct.

Okay, Robb, so tell us the stock number at VA Arms so we can order one?

I consider this a serious question.
