Hammer and trigger question ar-10

[jls67chevy]

Hello all,

My understanding is that the ar-10 and ar-15 trigger group is the same except for the hammer and hammer spring. Is this true?

Also has anyone used an ar-15 hammer and hammer spring on their ar-10 and experienced any problems?

On a side note: Does anyone know where someone might have ar-10 hammers and hammer springs in stock for sale?

Thanks for viewing!
