bolt head change

[carpet1]

I am changing the bolt head in 223 that came on a new model 10, going to .308 size [new bolt head]. Will the small parts exchange? What will I need besides the bolt head?

All the parts will exchange except for the extractor. The 223 extractor is different. I wouldn't swap the small parts. It's too cheap and easy to buy all the parts with the bolt head and keep them all complete.

You'll need a 308 magazine.
