When I upgraded my AR10 trigger my buddy told me to make sure I got a trigger designed for the AR10. His reasoning was the AR10 Bolt Carrier Group is heavier than the AR15. The extra mass could break the hammer on an AR15 trigger. Seemed reasonable to me so I got a CMC AR10 trigger....

Your friend work at an academy gun counter?
When the bcg begins reward motion, it's already in contact with the hammer, so it's not striking it, just pushing it: mass would make no difference.
The only difference you might find between a trigger sold as specifically made for an AR10 would be the hammer spring being a bit stronger because someone thought the AR15 hammer spring might not reliably ignite 308 primers. Survey says that was a lie.
BTW, CMCs triggers state "AR15/AR10" on their website. They don't sell separate triggers for each.
edit: hammer on those AR10 labelled triggers might be a bit bigger, for the same reasoning as the increased spring force. Again, unnecessary.
