Choosing the Right Tools for the Job
Selecting a Scope
Choosing the right scope that matches your intended use is paramount. Consider the range at which you’ll be shooting and the types of targets you will engage.
Selecting a Mounting System
Choosing the right mount is just as important as selecting the scope itself. The most common type of mount utilizes the Picatinny rail.
Gathering the Necessary Tools
Beyond the scope and mount, you will need a selection of tools. A quality torque wrench is highly recommended. A set of appropriately sized Allen wrenches or hex keys is essential. A level, or a leveling kit, is needed to ensure the scope’s reticle is perfectly aligned. Threadlocker will prevent screws from loosening due to vibration and recoil.
Preparing for Installation: Safety First
Before beginning the mounting process, always prioritize safety. Make absolutely sure that the firearm is unloaded. Point the muzzle of the rifle in a safe direction. The work area should be well-lit and organized.
Mounting the Mount: Securing the Foundation
The AR-15’s Picatinny rail should be cleaned. Using the torque wrench and the appropriate Allen wrench, tighten the screws of the mount to the manufacturer’s recommended torque specifications.
Preparing the Scope: Ring Installation and Alignment
If your mount uses rings, install the rings onto the mount, carefully following the manufacturer’s instructions. Place the scope inside the rings. Tighten the screws of the rings. Use the torque wrench to tighten the screws of the rings evenly and gradually, to the manufacturer’s recommended torque specifications.
Leveling the Scope: Ensuring Accuracy
A level reticle is essential for accurate shooting. A common technique is to use a bubble level. Following the specific instructions for your leveling method, make sure the reticle is perfectly vertical and horizontal. Once the reticle is level, tighten the scope ring screws to the manufacturer’s recommended torque.
Bore Sighting and Initial Zeroing: Hitting the Target
Bore sighting is the process of roughly aligning the scope with the rifle’s barrel. Adjust the scope’s windage and elevation turrets to move the reticle to the point of impact.
Fine-Tuning and Maintenance: Ensuring Continued Performance
Fine-tune the zero at the range. Regularly inspect the scope and mount. Clean the scope lens. Threadlocker should be applied to the screws on the scope rings and mount.
Troubleshooting Common Challenges
If the scope doesn’t hold its zero, several things could be at play. If your scope adjustments don’t seem to be working, first verify that you are turning the correct turrets (windage and elevation) in the correct direction. If the mount or rings become loose, the scope may begin to shift. If your eye relief is incorrect, you may experience a blurry image or a restricted field of view.
Conclusion: Elevating Your Shooting Experience
Mounting a scope on your AR-15 is a rewarding project. By following these steps, you can set up your rifle for precision and performance. Once the scope is installed, remember the importance of practice.
