For bolt action rifles, it seems must are OK with an oversized action. Custom sporters are one example, but I think there are a large number of manufacturers chambering outside the prime size for their actions.
Same with shotguns. Manufactures produce 20 ga shotguns in 12 ga actions. Same with the smaller gauges. I have read some even use the same barrel blank with a smaller bore moving the balance of the weight forward along with greatly increasing weight.
So, why not a 556 AR-10? What is the weight differential? That is, equal set-ups, how much would an AR-10 in 556 weigh over an AR-15 in 556?
It seems there would be issues with the gas system, but an upper with a lighter bolt, adjustable gas system, etc, would likely be able to resolve this issue.
My hands-on experience with an AR-10 is limited to the most basic of familiarization with operating the platform. I am quite ignorant.
A pound?
Certainly less than two pounds, right?
It seems like much of the extra bulk would be in the upper and lower receivers which are aluminum, so not that much weight difference.
I know Colt attempted this a little over five years ago and it didn't seem to be commercially successful. I didn't find a clear weight comparison of their 223 AR10 and a like AR15.
Typing this out made me think of a "widdle receiver" that would convert an AR-15 upper to run on an AR-10 lower. What a complicated beast that would be. Reliably converting my mini to stanag mags would be considerably simpler.
