Mounting a scope on your AR-15 can significantly enhance your shooting accuracy and overall experience. However, improper installation can lead to zeroing issues and even damage to your firearm. This comprehensive guide will walk you through the process, covering everything from choosing the right mount to the final adjustments.
Choosing the Right Scope Mount
The first and arguably most crucial step is selecting the appropriate scope mount. Several factors influence this decision:
-
Scope Ring Height: This is determined by the diameter of your scope's objective lens and the height of your AR-15's upper receiver. Too low, and your scope might hit the upper receiver; too high, and your cheek weld will be uncomfortable. Many manufacturers provide detailed specifications to help you choose the correct height.
-
Mount Type: The most common types are:
-
Standard Rings: These are the most basic and affordable option, offering a solid foundation for most scopes.
-
One-Piece Mounts: These offer a more rigid and potentially more accurate mounting solution, reducing the potential for shifting between the rings.
-
Picatinny/Weaver Mounts: These are the most versatile options, allowing for easy scope mounting and removal and compatibility with various accessories. Ensure your AR-15's upper receiver has a Picatinny rail.
-
-
Material: High-quality scope mounts are typically made from aircraft-grade aluminum or steel, offering exceptional durability and resistance to wear and tear.
-
Manufacturer Reputation: Stick to reputable brands known for their quality and precision engineering, such as LaRue Tactical, Aimpoint, and Vortex.
Tools and Materials You'll Need
Before you begin, gather the necessary tools and materials:
- AR-15 Rifle: Obviously! Ensure it's unloaded and the bolt is locked back.
- Scope: Your chosen optic.
- Scope Mount: The mount you selected.
- Torque Wrench: Essential for tightening the mounting screws to the correct specifications, preventing damage to your scope or mount. Using the wrong torque can seriously compromise the structural integrity of your mount and potentially damage your firearm.
- Allen Wrenches: These are usually included with the scope mount but verify this beforehand.
- Loctite (Optional): A small amount of blue Loctite can help secure the screws and prevent loosening during recoil.
Mounting Your Scope: A Step-by-Step Guide
-
Prepare the Mount: Carefully inspect your chosen scope mount for any damage or imperfections before proceeding.
-
Attach the Mount to the Rail: Align the mount with the Picatinny rail on your AR-15's upper receiver. Ensure it's properly seated and that the locking mechanisms are engaged.
-
Secure the Mount: Using your torque wrench, tighten the screws to the manufacturer's recommended torque specifications. This is critical to prevent damage to the mount and ensure a secure hold. Do not overtighten.
-
Mount the Scope: Carefully place your scope into the rings of the mount, ensuring it's centered and seated correctly.
-
Secure the Scope: Tighten the scope ring screws to the manufacturer’s specifications using your torque wrench. Again, do not overtighten.
-
Verify Alignment: Visually inspect your scope and mount for any misalignment. Everything should be straight and secure.
Zeroing Your Scope
After mounting your scope, you'll need to zero it. This involves adjusting the scope's windage and elevation turrets to align your point of aim with your point of impact. This process requires careful adjustment and practice at the shooting range.
Important Note: Always follow the manufacturer's instructions for both the scope and the mount. If you are uncomfortable performing this task yourself, consult a qualified gunsmith.
Conclusion
Mounting a scope on your AR-15 is a straightforward process if you follow the correct procedures. Choosing the right mount, using the appropriate tools, and paying close attention to detail will ensure a secure, reliable, and accurate shooting platform. Remember safety is paramount – always handle firearms responsibly.
