How to Mount a Scope on Your AR-15
Mounting a scope on your AR-15 can greatly enhance your shooting accuracy and overall experience. Whether you are a seasoned shooter or a beginner, knowing how to properly mount a scope on your AR-15 is essential. In this article, we will provide you with a step-by-step guide on how to mount a scope on your AR-15 effectively.
Step 1: Choose the Right Scope
Before you begin the mounting process, it is crucial to choose the right scope for your AR-15. Consider factors such as magnification power, reticle type, and objective lens size. Make sure the scope is compatible with your rifle and suits your shooting needs.
Example:
If you are using your AR-15 for long-range shooting, consider a scope with higher magnification power such as 4-16x50mm.
Step 2: Gather the Necessary Tools
Ensure you have all the necessary tools for mounting the scope on your AR-15. This may include a scope mounting kit, torque wrench, screwdriver, and level.
Tools Needed:
- Scope mounting kit
- Torque wrench
- Screwdriver
- Level
Step 3: Prepare Your AR-15
Before mounting the scope, ensure that your AR-15 is unloaded and the rifle is secured in a vice or gun rest. This will prevent any accidents during the mounting process.
Step 4: Install the Scope Rings
Start by attaching the scope rings to the rail of your AR-15. Use the torque wrench to tighten the screws securely but be careful not to over-tighten them as it may damage the scope or rail.
Tips:
- Use a level to ensure that the scope rings are aligned properly.
- Apply a small amount of thread locker to prevent screws from loosening over time.
Step 5: Mount the Scope
Carefully place the scope in the rings and adjust it to your desired eye relief. Once in position, tighten the screws on the rings evenly to secure the scope in place.
Note:
Make sure the reticle is level with the rifle before tightening all screws completely.

Step 6: Zeroing the Scope
After mounting the scope, it is essential to zero it for accurate shooting. Take your rifle to a shooting range and adjust windage and elevation settings until your shots hit the target where you aim.
Tips for Zeroing:
- Start at a short distance and gradually move back for long-range zeroing.
- Maintain consistency in shooting technique for precise adjustments.
Summary:
Mounting a scope on your AR-15 requires careful consideration of various factors such as choosing the right scope, gathering necessary tools, preparing your rifle, installing scope rings, mounting the scope, and zeroing it for accuracy. By following these steps and tips provided in this article, you can effectively mount a scope on your AR-15 and improve your shooting experience.
