Safety First: Your Most Important Consideration
The Critical First Step: Ensuring the Firearm is Unloaded
Before you even think about touching your Marlin .22, it is absolutely critical to prioritize safety. Firearms demand respect, and even seemingly simple tasks can become dangerous if proper precautions are ignored.
The very first step and, arguably, the most crucial is to **ensure the firearm is unloaded**. This means more than just visually checking the chamber. Begin by carefully removing the magazine (if your model has one). Once the magazine is removed, cycle the action to eject any rounds that may be in the chamber. Then, visually inspect the chamber to confirm it is empty. Point the muzzle in a safe direction (downrange, if possible) while you perform this check, and keep your finger off the trigger at all times. Repeat this process to triple-check. No matter how familiar you are with firearms, this process should be followed every single time.
Always wear appropriate eye protection – safety glasses are non-negotiable. Small pieces of metal and springs can fly during this process, and the consequences of a projectile striking your eye are devastating.
Work in a well-lit area with plenty of space. A cluttered workspace increases the chances of accidents, so clear the area of any unnecessary items. A gun vise or padded surface can be incredibly helpful in providing a stable platform for your rifle and protecting its finish.

Gathering Your Essential Tools and Materials
Essential Equipment for the Task
To successfully remove the rear sight from your 1970 Marlin .22, you’ll need a few essential tools. The right equipment makes the job easier and reduces the risk of damaging your rifle.
A correctly sized screwdriver is a must-have. This will likely be a flathead screwdriver, but confirm the exact type required for any screws that may be present on your particular sight. Ensure the screwdriver fits the screw heads snugly to avoid stripping them.
You will need a small punch or, preferably, a brass drift punch. This is a crucial tool for driving out the pin that secures the rear sight to the barrel. The brass material is softer than the steel of the pin, which reduces the likelihood of damaging the rifle. The size of the punch is important. A punch that is too small will not make contact with the pin and a punch that is too large might damage surrounding areas. Choose the correct size of the punch for your specific Marlin.
A hammer is required to use the punch. A small hammer, or even a gunsmith’s hammer, provides the necessary force to drive the pin out. Avoid using a hammer that is too heavy, as this could damage the rifle.
A non-marring mallet or plastic-headed hammer is optional, but can be useful. If the rear sight is particularly tight in the dovetail, you can gently tap it with this tool to help it loosen.
Protecting the finish of your rifle is paramount. Use a soft cloth, masking tape, or, even better, a gun vise with protective padding. This will prevent scratches and other cosmetic damage during the removal process.
Consider using a penetrating oil or lubricant. If the pin is stuck, applying a small amount of penetrating oil can help to loosen it.
Beginning the Removal Process
Step-by-Step Guide to Removing the Sight
With your tools and materials gathered and safety protocols firmly in place, you’re ready to begin removing the rear sight.
Repeat the most important step: **Ensure the Rifle is Unloaded!** Double-check the chamber and magazine to be absolutely sure.
Prepare your workspace. Place the rifle in a gun vise, if you have one, or on a padded surface. Secure the rifle firmly to prevent it from moving during the procedure. This will help prevent any accidental damage.
Locate the securing pin. The rear sight on most 1970 Marlin .22 models is secured to the barrel by a small pin. This pin usually runs horizontally through the sight base and the barrel. This pin is typically located on the side of the sight assembly. Carefully examine the sight assembly to pinpoint its location.
Removing the Securing Pin: The Key to Sight Removal
Removing the securing pin. This is where the punch and hammer come into play. Position the punch squarely on the pin. When removing the pin, it is important to get the direction correct. The vast majority of sights are designed to be driven out from the *left to the right*. Inspect the side of the sight to determine which side has a very slightly wider gap to accommodate the tapered pin. Make sure the punch is contacting the pin directly and squarely.
Begin tapping the punch gently with the hammer. The goal is to dislodge the pin. Avoid using excessive force initially. If the pin doesn’t budge, gently increase the force, but always be mindful of the potential for damage. If the pin appears to be stuck, apply a small amount of penetrating oil around the pin and allow it to sit for a few minutes. Re-attempt the removal after a bit of time has passed. Take extreme care to protect your eyes with the safety glasses during this process.
Once the pin starts to move, continue tapping until it is completely removed. Place the pin somewhere safe where it will not be lost.
Removing the Sight Itself
With the pin removed, the next step is to remove the sight itself. After the pin is removed, you may be able to gently tap the sight off. Before you do this, carefully look at which side the sight is located. This will dictate the direction in which you will tap. The sights are usually placed in a dovetail slot, and thus are tapered to fit very snugly. Using the non-marring mallet, or even the punch and hammer, you can apply controlled force on one side of the sight to drive it out of the dovetail.
It’s important to ensure the sight is being driven in the correct direction, because it’s designed to go one way and can easily be damaged if attempted incorrectly. In most cases, the rear sight will be driven out from the *right to the left*. Take note of the direction and tap, gently at first, ensuring the sight starts moving. Once it begins to move, you can carefully increase the force.
Post-Removal Considerations
What Comes After Sight Removal
Once the rear sight is removed, examine the dovetail slot for any dirt, debris, or damage. Clean the area thoroughly if needed. Use a solvent or cleaner suitable for firearms to remove any residue.
If you’re replacing the rear sight, make sure the new sight is compatible with your 1970 Marlin .22 model. This may seem obvious, but there are variations and you should ensure the replacement sight will fit properly.
Briefly, if you are re-installing a new sight, insert the sight into the dovetail slot. If the sight is tight, apply light pressure. Gently tap the sight into place, again using the non-marring mallet or punch and hammer. Use the pin to secure it in the slot. Aligning the sight can be done by eye at first, or you can sight down the barrel at a target. Adjust the sight until the shot is on target.
Troubleshooting Common Challenges
Addressing Potential Problems
Sometimes, things don’t go as planned. Here are some common problems and how to address them:
If the pin is stuck, penetrating oil is your friend. Apply the oil and let it soak in. If that fails, consider using a heat source on the pin, but do so with extreme caution and safety awareness. If it remains stubbornly stuck, it’s time to consult a qualified gunsmith. Forcing the pin can cause irreversible damage.
If the sight itself is stuck, ensure that you are tapping in the correct direction. Sometimes, corrosion or debris can bind the sight in the dovetail. Apply penetrating oil and allow it to work its magic. Make sure you have removed the pin before you attempt to remove the sight!
If you damage the sight or the dovetail during the process, it’s time for professional help. A gunsmith can often repair or replace damaged components, preserving the functionality of your rifle.
Always seek help from a qualified gunsmith if you are unsure about any step, or if you encounter significant difficulties. A gunsmith has the experience, tools, and expertise to safely and effectively perform the required tasks.
