Mounting a scope on your AR-15 can significantly enhance your shooting accuracy and overall experience. However, it's crucial to do it correctly to ensure both safety and optimal performance. This guide provides a step-by-step process, 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 zeroing, scope damage, and even safety hazards. Consider these factors:
1. Ring Height:
This is crucial for proper eye relief and clearance. Too low, and your scope might hit the receiver; too high, and your cheek weld will be uncomfortable and inconsistent. The height depends on your scope's diameter and the overall height of your AR-15's upper receiver. Many manufacturers provide guidelines on recommended ring heights for their specific scopes. Measure your scope's diameter and consult the manufacturer's specifications or a reputable retailer for guidance.
2. Mount Type:
- Picatinny Rail Mounts: These are the most common type for AR-15s. They utilize the standard Picatinny rail integrated into the upper receiver. Ensure your chosen mount is compatible with the Picatinny rail standard.
- Integrated Mounts: Some AR-15 uppers come with integrated scope mounts. These are usually one-piece designs, eliminating the need for separate rings.
- Offset Mounts: These allow for mounting the scope slightly to the side, which can be beneficial for certain shooting positions. However, they can impact zeroing and are typically less common.
3. Material and Construction:
High-quality mounts are typically made from aluminum or steel and are built to withstand recoil. Look for mounts that are robust, well-constructed, and from reputable brands. Avoid cheap, flimsy mounts that could compromise your safety and accuracy.
Tools and Materials You'll Need:
- AR-15 with a Picatinny rail
- Chosen scope and rings (or integrated mount)
- Appropriate sized Allen wrenches or torque wrench
- Scope mounting instructions (consult manufacturer's guidelines)
- Level (optional, but highly recommended for precise alignment)
- Cleaning patches and solvent (to clean the rail before mounting)
Mounting Your Scope: A Step-by-Step Process
-
Prepare the Rail: Clean the Picatinny rail thoroughly with cleaning patches and solvent to remove any dirt or debris. This ensures a secure and stable mount.
-
Mount the Rings (if applicable): Carefully attach the rings to the Picatinny rail according to the manufacturer's instructions. Tighten the screws evenly and gradually, avoiding over-tightening, which can damage the rings or rail.
-
Install the Scope: Gently place your scope into the rings, ensuring it's centered and sits securely.
-
Secure the Scope: Tighten the scope ring screws evenly and gradually to the manufacturer's specified torque. Using a torque wrench is highly recommended to avoid over-tightening and potential damage.
-
Level the Scope: Use a level to ensure your scope is perfectly level. This is crucial for accurate zeroing. Make any necessary adjustments before tightening the rings completely.
-
Double-check: Once everything is secure, carefully inspect your setup. Ensure the scope is properly seated and all screws are securely fastened. Any looseness or wobble could compromise accuracy and safety.
Zeroing Your Scope
After mounting, you’ll need to zero your scope. This involves adjusting the scope’s adjustments to match the point of impact with your point of aim at various distances. This is a separate process and typically involves firing test shots at a target and making incremental adjustments until the point of impact aligns with the point of aim.
This process requires practice, patience and a proper understanding of your weapon and sighting system. Consider seeking guidance from experienced shooters or professionals if you're unfamiliar with the process.
Conclusion
Mounting a scope on an AR-15 properly involves careful planning and execution. By following these steps and choosing the right equipment, you can significantly improve your shooting accuracy and enjoy a more enhanced shooting experience. Remember safety is paramount; always handle firearms responsibly and consult with experts when needed.
