Hello. First post. I've recently received an older 110E in .270 thats in been in the family a long time. Started going through it. The forward action screw was rubbing the underside of the bolt head. The bolt stamping matches the receivers serial numbers. So they must be a matched pair. So can I replace just the bolt head? Do I even need to replace it? Ive got some good pics, just havent figured out how to post yet. Thanks!
