To disassemble the bolt on a Browning X-Bolt, first ensure the rifle is unloaded and pointed in a safe direction. Remove the bolt by pulling the bolt release lever located on the side of the receiver while simultaneously pulling the bolt rearward. Once the bolt is removed, you can disassemble it by pulling the bolt handle back and rotating it counterclockwise to unlock and separate the bolt body from the bolt head. Be cautious not to lose any small parts during the process.
Grab the cocking piece in a smooth jaw vise, pull the bolt and shroud foreward and unscrew the bolt. To re-assemble, with the cocking piece in the vise, push the shroud foreward and screw the bolt back on.
