Step-by-Step Guide To Mounting A Rifle Scope


To properly mount a rifle scope, there are several steps you need to follow including choosing the right scope, preparing your firearm, gathering necessary tools and hardware, installing the scope base and rings, positioning and leveling the scope with torque value in mind.

Choosing The Right Scope

When it comes to choosing the right rifle scope for your firearm, there are several factors you need to consider. First and foremost is the type of shooting you will be doing.

Will you be hunting or target shooting? Do you need a long-range or short-range scope? Once you have determined your specific needs, consider the magnification power of the scope.

Another important aspect to consider when choosing a rifle scope is its reticle. Reticles come in different shapes and sizes, each with its own benefits.

For example, crosshairs are simple and straightforward while BDC (bullet drop compensator) reticles take into account bullet drop at different ranges making them great for long range shots.

Preparing Your Firearm

Before you begin mounting your rifle scope, it’s important to properly prepare your firearm. Make sure to unload and clear any ammunition from the gun, ensuring that there is no round in the chamber or magazine.

Once the firearm is unloaded, you can proceed with removing any existing scope or sights. Ensure that all components are removed cleanly and thoroughly before proceeding with attaching the new base for your rifle scope.

It’s also a good idea to give your firearm a thorough cleaning at this point to ensure optimum performance during use.

Gathering The Necessary Tools And Hardware

Before mounting your rifle scope, you’ll need to gather the necessary tools and hardware.

First and foremost, make sure you have the correct scope rings for your specific firearm. This is crucial for ensuring proper alignment of the scope with your gun’s barrel.

Additionally, you will need a torque wrench and socket heads to tighten screws accurately without stripping them.

By having all the required tools and materials on hand before beginning, not only will your job be easier but also more accurate when it comes to securing your rifle scope in place correctly.

Installing The Scope Base And Rings

Once you have chosen the right scope for your firearm, it’s time to install the scope base and rings. This step is crucial in ensuring that your rifle scope stays secure and stable while shooting.

First, select a solid mounting location on your firearm that will allow enough clearance for proper eye relief.

Carefully attach the rings to the base before affixing them onto your firearm with screws. It’s important to use just enough torque pressure without over-tightening to avoid damage or misalignment.

Additionally, some shooters prefer using anti-seize compound on their screws and bolts to prevent corrosion or rust buildup over time.

Positioning And Leveling The Scope

Once you have chosen the right scope and installed the base and rings, it’s time to position and level your rifle scope.

The proper placement depends on a few factors like personal preference, firearm type, and shooting style- but typically most hunters place their scopes 1.5 inches-2 inches away from their eyes.

Leveling is critical in ensuring accuracy when using your rifle scope. When mounting your rifle scope, make sure both it and the gun are leveled horizontally by placing a leveling tool on top of each.

A bubble or digital leveler can make this process easier for you to determine whether there is any tilt present that needs correcting before adjusting the elevation or windage knobs.

By keeping these tips in mind when positioning and leveling your rifle scope correctly, shooters can improve their marksmanship abilities significantly, giving them better hunting experiences with greater accuracy on every shot taken downrange!

Tightening The Scope And Checking For Accuracy

Once you’ve installed the scope base and rings, it’s time to attach your rifle scope. First, make sure everything is secure by hand-tightening each screw before using a torque wrench to achieve the recommended torque value.

With everything snugly in place, check the accuracy of your rifle by adjusting windage and elevation knobs until you have proper sight alignment.

Take a few practice shots at a target on the range or in an open field to ensure that your adjustments are correct.

Tips And Troubleshooting For Properly Mounting A Rifle Scope


To ensure a secure and stable mounting of your rifle scope, it’s important to follow these tips: use the correct torque value for screws, avoid over-tightening, check for alignment and leveling, and consider using Loctite or anti-seize compound.

Using The Correct Torque Value

Using the correct torque value is crucial when mounting a rifle scope to your firearm. The torque is the amount of force used to tighten screws, and not using the appropriate level of torque can lead to damage to your scope, or worse, your firearm.

To achieve proper tightening, use a torque wrench and set it at the manufacturer’s recommended setting. Avoid over-tightening as this can cause stress on both the scope and firearm’s threads, leading them to become worn out quickly.

Using too little torque may result in loose screws causing misalignment and inaccurate shots.

Avoiding Over-Tightening

While it is important to secure your rifle scope properly, it’s equally crucial not to over-tighten it. Over-tightening can cause damage or even break the screws in the mount or rings, compromising accuracy and stability.

To avoid over-tightening, use a torque wrench set to the correct value for your hardware. Be sure not to exceed that value when tightening the screws into place.

Another tip is to use anti-seize compound or blue Loctite on the threads of your mounting screws.

Properly mounted scopes increase accuracy and make for an enjoyable shooting experience while minimizing accidents caused by malfunctioning equipment.

Checking For Alignment And Leveling

After attaching the scope rings, it’s crucial to ensure that your rifle scope is level and aligned with your firearm. This step plays a significant role in enhancing accuracy while shooting.

First, you need to position your rifle in such a way that it remains stable on a leveled surface.

It’s also essential to align your rifle scope properly so that its crosshairs are parallel with the bore axis of your firearm. Failure to do this may result in shots drifting away from their intended target, reducing accuracy while shooting.

Additionally, make sure that all screws are tightened up using appropriate torque values for secure attachment without over-tightening them resulting in damaged threads or other issues.

Using Loctite Or Anti-Seize Compound

When mounting a rifle scope on your firearm, using Loctite or anti-seize compound can help to keep the screws and hardware in place. This is especially important for those who plan to use their firearm for hunting or shooting activities that involve a lot of movement.

Loctite is a brand of thread-locking adhesive that can be applied to the threads of screws before they are inserted into the holes on your scope rings or base. On the other hand, anti-seize gives you an easier way to remove them if needed without damaging any parts of your equipment.

Always practice caution when applying either compound so as not to get it onto any part of your optics system like lenses and reticles.

Troubleshooting Common Issues

A properly mounted scope is essential for accuracy and precision in shooting. However, even with the best efforts, issues may arise during and after the installation process. Here are some common problems and troubleshooting tips to help you achieve a secure and stable rifle scope mount:

  1. Loose screws or rings: Check all screws, including the base screws, ring screws, and scope mounting screws. Use proper torque values specified by the manufacturer and avoid over-tightening that could damage the threads or distort the components.
  2. Misaligned or tilted reticle: Ensure that the scope is level both vertically and horizontally before tightening down the rings. Use bubble levels or laser alignment tools for more precision.
  3. Crosstalk or parallax error: Parallax occurs when there is a shift between your eye’s position behind the eyepiece lens and the reticle’s focal plane inside the scope tube. To correct this issue, adjust your eye relief distance, focus on your target clearly, center your reticle precisely on your intended target.
  4. Poor image quality: If you’re experiencing blurry images or insufficient brightness in low light conditions, check if there are any debris or smudges on either of your lenses’ surfaces. Try cleaning them with a lint-free cloth or using an optic-safe cleaner.
  5. Scope won’t hold zero: This problem can be caused by improper mounting procedures as well as recoil’s impact on parts coming loose over time (as noted above). Checking for movements after each shot can help maintain zero in these cases.
  6. Damage to internal components: Keep in mind that scopes are delicate instruments that should be treated accordingly to prevent damage from shocks due to accidental drops or rough handling during hunting trips.

With these troubleshooting tips at hand and taking care of regular maintenance steps like cleaning lenses regularly will ensure their longevity while also improving marksmanship out in field or range environments without needing vitamin supplements!
