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.

To disassemble the Cooey Model 60 bolt, first ensure the firearm is unloaded and the safety is engaged. Remove the bolt by pulling the bolt handle fully back and then lifting it out of the receiver. Next, locate the bolt stop and push it down to release the bolt body from the bolt handle. Once separated, you can further disassemble the bolt by removing any screws or pins as needed for cleaning or maintenance. Always refer to a specific manual for detailed instructions.
