I have a older model 110 chambered in 270 win. I would like to rebarrel it to a 223 rem. I have take the bolt apart and put it back together for experience. My question is what all do I need to change the bolt for a 223rem. Do I need the bolt head only? if so does anyone recommend a place or have a link were to purchase the parts. Any help would be greatly appreciated.

Thanks,
Brandon
