Replacing the barrel on your Ruger Precision Rimfire (RPR) is a rewarding upgrade that can significantly enhance accuracy and shooting experience. Whether you're looking to switch calibers (though that's not possible with the RPR), experiment with different barrel profiles, or simply replace a worn-out barrel, this guide provides a detailed walkthrough of the process. Remember, always prioritize safety and follow all manufacturer instructions.
Tools and Materials Needed
Before you begin, gather the necessary tools and materials:
- New Ruger Precision Rimfire barrel: Ensure it's compatible with your specific RPR model. Confirm the caliber and threading specifications.
- Action wrench: A properly sized action wrench designed for the RPR is crucial to prevent damage to the receiver. Improper tools can easily strip the threads.
- Barrel nut wrench: This specialized wrench is needed to tighten and loosen the barrel nut.
- Torque wrench: Accurate torque is vital to ensure proper barrel installation and prevent damage. Consult your new barrel's instructions for the recommended torque specifications.
- Thread locker (optional): A high-quality thread locker, such as Loctite 242, can help prevent the barrel nut from loosening over time.
- Cleaning supplies: You'll need to thoroughly clean the receiver and barrel threads before installation.
- Gunsmithing vise (recommended): A vise will help stabilize the rifle during the barrel removal and installation process. Use soft jaws or protective material to avoid marring the receiver.
- Protective eyewear and gloves: Always protect your eyes and hands when working with firearms.
- Firearm cleaning solvent and patches: To clean the receiver and threads after removing the old barrel.
- Pencil and paper: It is helpful to take pictures or notes to remember how the parts go back together.

Step 1: Unloading and Safety Check
Absolutely critical: Ensure your Ruger Precision Rimfire is completely unloaded and clear of any ammunition. Visually and physically inspect the firearm to confirm it's safe.
Step 2: Removing the Old Barrel
- Secure the rifle: Use a gunsmithing vise, ensuring the receiver is securely clamped but not damaged.
- Loosen the barrel nut: Using the barrel nut wrench, carefully loosen the barrel nut counterclockwise. Avoid applying excessive force.
- Remove the barrel: Once the barrel nut is loose, carefully remove the old barrel from the receiver. Note the orientation of the barrel and any markings to ensure correct reinstallation.
Step 3: Cleaning the Receiver
Thoroughly clean the receiver threads and barrel threads using a cleaning solvent and patches. Remove any debris, old thread locker, or residue that could interfere with the new barrel's installation.
Step 4: Installing the New Barrel
- Apply thread locker (optional): If using a thread locker, apply a small amount to the threads of the barrel nut.
- Install the new barrel: Align the new barrel with the receiver, ensuring it's properly seated.
- Tighten the barrel nut: Using the barrel nut wrench, carefully tighten the barrel nut.
- Torque the barrel nut: Use the torque wrench to tighten the barrel nut to the manufacturer's recommended specifications. Over-tightening can damage the receiver.
Step 5: Function Check
After completing the installation, perform a thorough function check to ensure the rifle operates correctly. Dry fire the rifle (always with the muzzle pointed in a safe direction) to check the bolt’s movement.
