Gathering Your Essential Tools and Materials
Required Materials
Before embarking on this journey, the first step is to gather all the necessary tools and components. Having everything readily available streamlines the process and prevents frustrating interruptions. Let’s break down what you’ll need.
The core components are straightforward. You’ll require, first and foremost, the rifle itself. Then comes the scope, the optical device that will magnify and clarify your target. You’ll also need scope rings. These connect the scope to the rifle, so ensuring compatibility is crucial. Scope rings must be the correct size to fit both the scope tube and the mounting system on your rifle. If your rifle does not already have a mounting base, you’ll need to acquire one, matching it to your rifle’s action and the scope rings you’ve selected.
Beyond these fundamental components, several tools are critical for a successful and accurate mounting process. A screwdriver is essential for tightening the various screws involved. Be certain to have the correct size and type of screwdriver that fits the screws on your rings and mounting base. A torque wrench is strongly recommended. Tightening screws to the correct torque specification is essential to prevent damage to the scope, rings, or base, and it helps prevent slippage. A level, whether a standard bubble level or a scope-specific leveling tool, is a vital instrument for ensuring the scope is perfectly aligned with the rifle’s vertical axis.
Consider also including blue thread locker, such as Loctite. Thread locker helps to prevent the screws from loosening due to recoil and vibration, maintaining the scope’s zero. Cleaning solvent or degreaser, along with cleaning patches or lint-free cloths, are also good items to have on hand for prepping and cleaning the various parts.
Though not strictly essential, some optional tools can greatly enhance the process. Scope mounting alignment tools, like a lapping bar, can help ensure a perfect fit between the rings and the scope tube. This minimizes stress on the scope body. Lens cleaning supplies, including lens cleaning fluid and a microfiber cloth, are also useful for maintaining the clarity of your optic.
Preparing Your Firearm and Optic for Mounting
Safety First
Before you begin any work, safety must be your absolute top priority. Always handle firearms with extreme caution. Ensure that the rifle is unloaded, and the action is open. Check the chamber physically and visually to confirm it’s empty. Point the muzzle in a safe direction, away from yourself and others, at all times. It’s essential that you keep all of your safety rules at the front of your mind.
Once you’ve verified the firearm is unloaded, you can start preparing the components. Begin by thoroughly cleaning the scope and rings to remove any oil, grease, or debris that may be present. This ensures proper contact between the surfaces and helps maintain a secure mount. Use a cleaning solvent or degreaser and the cleaning patches or cloths.
Inspect the scope itself, the rings, and the mounting base (if applicable) for any signs of damage, such as dents, scratches, or loose parts. If you notice any damage, do not proceed. Contact the manufacturer or a qualified gunsmith.
Finally, if you are replacing a previous base, or if your rifle’s receiver needs cleaning, clean the mounting surface on the rifle receiver with cleaning solvent. Remove any existing adhesive or residue. A clean mounting surface is essential for a secure and reliable base installation.
Installing the Mounting Base (If Necessary)
Base Selection
If your rifle does not already have a mounting base installed, this is the next step. The type of base you will need depends on your rifle’s action and your scope rings’ style. There’s no single universal base; the best option will match both. Common options include Picatinny rails, which offer versatility and ease of use, and Weaver bases, which are also widely used.
The most important thing is to choose a base that is compatible with your rifle receiver and your scope rings. Check the specifications to ensure a perfect fit.
The base installation process will vary slightly depending on the type of base and your rifle. However, some general guidelines apply. Follow the manufacturer’s instructions carefully. Clean the mounting surfaces on your rifle’s receiver thoroughly before installing the base. This ensures proper adhesion and a secure mount.
Align the base correctly with the rifle’s action. The base must sit straight and be properly aligned to give your scope the ability to sight correctly. If your base uses screws, apply blue thread locker to the threads. This will prevent the screws from loosening due to recoil. Tighten the screws to the recommended torque specification using a torque wrench. Overtightening can strip the threads, while undertightening can lead to a loose mount. Refer to the base manufacturer’s specifications for the proper torque settings.
Mounting the Scope Rings: A Crucial Step
Ring Sizing and Alignment
The scope rings are the vital link between your rifle and your scope. Before beginning, confirm the proper sizing. Choosing the correct ring size is critical. Scope rings are sized according to the diameter of the scope’s main tube. This diameter is usually indicated on the scope’s specifications (e.g., 1-inch or 30mm). Measure the main tube of the scope to confirm, and then choose rings that correspond with that measurement. Consider ring height too, which will depend on the objective lens diameter of the scope and how high you want the scope to sit above the rifle.
To install the rings, begin by loosely attaching the bottom halves of the rings to the mounting base. Leave the top ring halves detached for now.
With the bottom rings in place, it’s time to align the rings. While you can attempt this by eye, using scope ring alignment tools, like lapping bars, is highly recommended for achieving precise alignment. Misalignment puts stress on the scope body and can affect accuracy. The process of lapping your rings may improve accuracy by evening out minor imperfections in the rings.
Before securing the top halves of the rings, apply blue thread locker to the screws. Tighten the screws to the manufacturer’s recommended torque specification using a torque wrench.
Placing the Scope in the Rings and Perfecting the Eye Relief
Scope Positioning
Carefully set the scope into the rings. The next important step is to position the scope properly. Consider eye relief, which is the distance between your eye and the scope’s eyepiece when you have a full field of view. Proper eye relief ensures a comfortable shooting position and helps prevent eye strain. Too little eye relief and you risk getting “scope bite” from recoil, and too much means you might not be able to see the full field of view. Adjust the scope’s position in the rings until you find the optimal eye relief for your shooting style.
Make sure the crosshairs are properly aligned, and that the scope is level.
Precise Leveling of the Scope
Leveling Methods
Leveling the scope is paramount to accuracy. If the scope is not level, the reticle will be canted, leading to inaccuracies at longer ranges. There are several methods to achieve proper leveling. You can use a dedicated scope-leveling tool or a level.
One method involves placing a level across the top of the scope’s elevation turret. Another method involves using a leveling wedge between the scope and the rings. However you choose to do it, the goal is to get the reticle level with the rifle.
You can also use external levels. Place a level on a flat surface on the rifle and level it before you mount the scope. Then make sure the scope is level with the top of the rifle.
Once you are satisfied that the scope is level and the rings are properly tightened, you are on your way to hitting the target.
Final Tightening and Inspection
Verification
Before you can consider the scope truly mounted, it is important to double-check. Tightening the rings onto the scope involves alternating tightening between the top screws of the rings, in a cross-pattern. Tighten screws gradually, a little bit at a time, to ensure even pressure. Using a torque wrench is crucial here. This will help prevent damage to the scope tube. Over-tightening can crush the scope, while under-tightening may lead to slippage.
Consult the manufacturer’s recommendations for the precise torque specifications.
Once the rings are tightened, it’s time for a visual inspection. Recheck all screws for tightness. Ensure that the scope is properly aligned. Make sure the lenses are clean and free of any obstructions.
Checking for Zero and Fine-Tuning
Range Testing
Once the scope is mounted, it’s time to head to the range to confirm your zero. Bore sighting is an optional but useful step you can take before heading to the range. Bore sighting involves looking through the bore of the rifle and aligning the reticle to that visual line.
At the range, begin by firing a few shots at a target. Observe where your shots impact the target and adjust the scope’s windage and elevation turrets accordingly to bring the point of impact (POI) to the point of aim (POA). Make small adjustments to the scope’s turrets, usually measured in minutes of angle (MOA) or milliradians (mils).
Once you are hitting the target where you desire, it is a good time to declare success.
Common Problems and Solutions
Troubleshooting
There are a few issues that can sometimes crop up, and knowing how to address them is beneficial.
Scope ring marks can occur if the rings are overtightened or if they are not perfectly aligned. Using lapping tools can help. Another solution is using rings with internal cushioning materials that can minimize the potential for marks.
Another potential issue is scope movement. This might occur if the rings are not sufficiently tightened. The solution is to tighten all the screws, including the ones holding the base to the rifle.
If you are still encountering issues with accuracy, after mounting the scope, make sure it is aligned with the bore. If the scope is tilted, your shots can be off at longer distances.
