Mounting a scope on your AR-15 can significantly enhance your shooting accuracy and overall experience. However, doing it correctly is crucial for both safety and performance. This comprehensive guide will walk you through the process step-by-step, covering everything from choosing the right mounts to zeroing your scope.
Choosing the Right Scope Mount
Before you even think about mounting, selecting the appropriate scope mount is paramount. The wrong mount can lead to inaccurate shooting, scope damage, and even safety hazards. Here's what to consider:
1. Ring Height:
This is crucial for proper eye relief and clearance. Too low, and you risk your scope hitting the charging handle or upper receiver. Too high, and your cheek weld will be uncomfortable and inconsistent. Consider the diameter of your scope's objective lens and the height of your AR-15's upper receiver when choosing ring height. Many manufacturers provide detailed specifications to help with this selection.
2. Mount Type:
- Picatinny/Weaver Rails: Most AR-15s come equipped with a Picatinny rail on the upper receiver. This is the standard mounting system, offering a secure and versatile platform. Ensure your scope rings are compatible with this rail type.
- Offset Mounts: These allow you to mount your scope at an angle, often useful for close-quarters shooting or when using a red dot sight alongside a magnified scope.
- Material: High-quality scope mounts are typically made from aircraft-grade aluminum or steel. These offer superior durability and stability compared to cheaper alternatives.
3. One-Piece vs. Two-Piece Mounts:
- One-Piece Mounts: These are generally preferred for their rigidity and increased accuracy. They offer a single, solid connection between the scope and the rail.
- Two-Piece Mounts: These offer more adjustability but can be slightly less rigid than one-piece mounts.
Tools and Materials You'll Need
Before you begin, gather the necessary tools and materials:
- AR-15 Rifle: Obviously!
- Scope: Your chosen optic.
- Scope Mount: Chosen based on the considerations above.
- Torque Wrench: This is essential to prevent over-tightening and potential damage to your mount or rifle. Use the torque specifications provided by your mount manufacturer.
- Allen Wrenches/Screwdrivers: These will vary depending on your mount and scope.
- Cleaning Kit (optional): For cleaning your rifle before handling.
- Eye Protection: Always wear safety glasses when working with firearms and tools.
Mounting Your Scope: A Step-by-Step Guide
-
Prepare Your Rifle: Ensure your rifle is unloaded and the bolt is locked back. Thoroughly inspect the Picatinny rail for any debris or obstructions.
-
Mount the Rings: Carefully attach the scope rings to the Picatinny rail. Tighten them securely using the appropriate Allen wrench or screwdriver, but do not overtighten. Use your torque wrench to ensure proper torque.
-
Install the Scope: Carefully place your scope into the rings, ensuring it's properly seated and aligned. Tighten the ring caps using your torque wrench, again adhering to the manufacturer's specifications.
-
Check Alignment: Visually inspect the scope to ensure it's perfectly aligned on the rail. Any misalignment will negatively impact accuracy.
-
Zeroing Your Scope: This is a crucial final step. Follow the instructions specific to your scope and rifle to zero your optic at various distances.
Important Safety Precautions
- Always handle firearms responsibly. Treat every firearm as if it were loaded.
- Never point a firearm at anything you do not intend to shoot.
- Keep your fingers off the trigger until you are ready to shoot.
- Always wear eye protection.
Conclusion
Mounting a scope on your AR-15 is a straightforward process when you follow the right steps. Choosing the correct mount, using the proper tools, and carefully following the instructions will ensure your scope is mounted securely and accurately. Remember to prioritize safety and always practice responsible firearm handling. Proper zeroing is crucial for optimal performance. Consult your scope's manual and online resources for specific zeroing instructions.
