Looking at building a very, very light carbine, just for fun and need to order an upper receiver. I'm wondering if anyone knows the weights of A2, A1, and flat-top uppers (forward assist versions).

I don't know weights, but if you want really light, you want a pencil barrel, or lightweight barrel, and a light forearm. Think carbon fiber.
I have no idea of the weight of my .300 BLK (http://www.thehighroad.org/attachment.php?attachmentid=174610&d=1352692527), but it is very light, even with the scope on it. The lightweight barrel with no front sight, just a low profile gas block, is most of the reason why.
I can weigh it later.

Yep, that's the plan. Pencil barrel (.223) & carbon fiber.
Just don't know how much uppers weigh. I'm trying to shave every ounce of weight that I can.
Hmmm... Are your scope rings mounted backwards?

No, although the scope is mounted further forward now.
