[yardbart]

Will any of the other manufactures bolt assemblies or bolt and carrier assemblies work in the Armalite AR-10 upper's?

Thanks,

I don't know for a fact either way, but I have no good reason to find out. None are truly "mil-spec. My advise is to find someone with the one of the other AR-10 clones and ask them to let you check it for fit, I won't even swap bolts in my own rifles (all DPMS) . The bolts are different for the 308 and 300 SAUM models in the same brands,
