Thanks to the Savage-compatible action on the ARC Mausingfield action, changing barrels can be done easily without the need for a gunsmith to fit a barrel. Thanks to the ease with which barrels can be swapped out, it's possible to change calibers relatively easily on this action, and that's where the Mausingfield Bolt Head and Extractors Kits come in handy. Available in a range of popular calibers, these kits can be used on Mausingfield rifles developed in 2019 or later and provides owners with the ability to change calibers on their rifle. The bolt head included in this kit is machined from hardened steel and features a DLC coating that prevents premature wear and corrosion.
