Aftermarket barrels offer various performance enhancements, like tighter tolerances. Research your options carefully and select a barrel that aligns with your shooting goals. Be aware that a good quality barrel can make a world of difference in your accuracy.
Action Wrench
This specialized tool is crucial for safely removing and installing the barrel. The action wrench is specifically designed to grip the receiver of the Savage Mark II securely. There are different types of action wrenches; ensure you choose one designed to fit your specific model. Using an incorrect wrench can lead to damage to your receiver.
Barrel Vise or Clamping System
This is used to securely hold the barrel during the barrel change process. A barrel vise is the preferred tool, offering a solid and reliable grip. It prevents the barrel from rotating while you apply force to the action wrench. Be sure to use appropriate barrel vise pads to protect the barrel’s finish.
Torque Wrench
Essential for ensuring the barrel is tightened to the correct torque specifications. Over-tightening can damage the action or the barrel, while under-tightening can lead to accuracy issues and potential safety problems.
Cleaning Supplies
You will need a cleaning rod, bore brushes, patches, and a high-quality bore cleaner specifically designed for .22 rifles. This is for cleaning and preparing the action threads before installing the new barrel, and for cleaning the barrel after installation.
Small Hammer and Punch
You may need these to remove any pins during disassembly, especially if you choose to remove the trigger assembly (which isn’t always necessary).
Thread Locker
Specifically, a product like Loctite or a similar thread-locking compound. This helps secure the barrel to the action and prevent it from loosening due to recoil. Choose the correct type of thread locker, consulting product recommendations for rifle barrels.
Anti-Seize Compound or Grease
Apply a small amount of high-temperature anti-seize compound to the barrel threads. This prevents corrosion and makes future barrel changes easier.
Shop Towels or Rags
To keep your workspace clean and to wipe up any excess lubricants or solvents.
Optional Equipment: Bore Scope
A borescope allows you to visually inspect the inside of the new barrel for any imperfections or defects before installation, or to inspect the barrel after installation.
Dismantling the Savage Mark II
With safety procedures firmly in place and your tools assembled, it’s time to start the disassembly process. Take it slow, and pay attention to detail.
Removing the Action from the Stock
Carefully remove any screws that secure the action to the stock. These screws are typically located in the trigger guard area and potentially in front of the magazine well.
Once the screws are removed, gently lift the action out of the stock. You may need to gently wiggle or tap the action.
Store the stock in a safe place, away from the work area.
Bolt Assembly Removal
With the action out of the stock, open the bolt.
Locate the bolt release lever (the specific location may vary slightly depending on the exact model of your Mark II).
Engage the bolt release lever, while simultaneously pulling the bolt out of the receiver. The bolt should slide out easily.
Set the bolt assembly aside.
Trigger Assembly Disassembly (Optional)
While not always necessary, removing the trigger assembly can sometimes provide better access to the barrel.
Identify and remove any pins or screws that secure the trigger assembly to the action.
Carefully remove the trigger assembly. Note the orientation of the parts for reassembly.
Store these parts safely.
Separating the Old: Barrel Removal

Securing the Action
Place the action securely into the barrel vise, ensuring the action is properly seated and clamped. Use the correct barrel vise pads to avoid damage to the receiver. Tighten the vise securely, but avoid over-tightening.
Positioning the Action Wrench
Carefully position the action wrench on the receiver. Make sure the wrench is properly seated and fully engaged on the flats of the receiver.
Applying Force and Loosening the Barrel
Using the appropriate wrench, slowly and steadily apply force to loosen the barrel. The barrel will typically unscrew in a counter-clockwise direction. Be aware that it may take considerable force to break the initial seal, which can require effort.
Work slowly, checking for movement. The barrel should begin to rotate.
Optional Heat Consideration
Occasionally, a barrel can be stubborn to remove. *Use heat with extreme caution*. Using a heat gun may help to loosen the barrel. *Use only if you are comfortable and familiar with working with heat and firearms*. Apply heat cautiously and evenly to the area where the barrel and receiver meet. Remember, excessive heat can damage the firearm. Be careful not to overheat. Allow the metal to cool before attempting to loosen the barrel again.
Complete Removal
Once the barrel is loosened, continue unscrewing it from the action. The barrel should unscrew completely.
Carefully remove the old barrel from the action.
Bringing in the New: Barrel Installation
With the old barrel removed, you’re ready to install the replacement.
Preparing the New Barrel
Before installation, thoroughly clean the threads on the receiver. This will help ensure proper seating and prevent corrosion.
Apply a small amount of thread locker to the threads on the barrel. This helps secure the barrel and prevent it from loosening. Follow the manufacturer’s instructions for the thread locker.
Apply a thin layer of anti-seize compound to the barrel threads. This will prevent galling, corrosion, and make future barrel changes easier.
Threading the New Barrel
Carefully thread the new barrel into the receiver by hand, taking care not to cross-thread the barrel.
Continue to thread the barrel until it is snug against the action.
Final Tightening and Torqueing
Using the action wrench, finish tightening the barrel. It is essential to tighten the barrel to the manufacturer’s recommended torque specifications. Over-tightening or under-tightening can lead to poor accuracy or, in rare cases, damage.
