Each caliber has a specific size bolt which will correspond with that specific caliber rifle. Since each rifle and bolt will have a variance with head-spacing, the factory must examine each specific firearm and “fit” the bolt to that specific rifle. If you wish to send your firearm in for a replacement bolt, be sure to get a Service Request (SR) number before sending in your rifle. You can obtain this by calling us at 1-800-243-9700.
