A couple questions about the AR10 and like guns: The trigger, hammer and disconntor, are they same one's used in the 223 guns?
How much bigger is the bolt carrier than the carrier from AR15(223)...
Thanks...

Completely different systems. The 7.62 NATO AR's are super sized, the BCG's don't interchange with the 5.56mm models.

The FCG's are the same, I *believe*.

I can only speak for the DPMS LR-308. Yes it does have the same fire control group as the 5.56 AR and I'm in the process of installing a Geissele match trigger in it. But the bolt carrier group is much bigger. It looks like a scaled-up AR BCG and disassembles the same way except the firing pin retainer is not a cotter pin; it's a much bigger "regular" pin.
