The Ultimate Guide to Choosing the Best AR Scope Mount

Selecting the right optic for your AR-15 is a crucial step in optimizing its performance, but it’s only half the battle. The unsung hero in achieving pinpoint accuracy is the scope mount. The best AR scope mount not only secures your optic but also ensures proper eye relief and consistent zero. This comprehensive guide will walk you through the critical factors to consider when choosing the best AR scope mount for your specific needs.

Understanding the Importance of a Quality AR Scope Mount

A subpar scope mount can lead to a host of problems, including shifting zero, inconsistent accuracy, and even damage to your optic. Investing in a high-quality AR scope mount is an investment in the overall performance and reliability of your rifle. A reliable mount provides a stable and repeatable platform for your scope, allowing you to confidently engage targets at various distances. Think of it as the foundation upon which your accuracy is built. Without a solid foundation, even the most expensive optic will struggle to deliver consistent results.

Factors Influencing Scope Mount Selection

Several factors play a crucial role in determining the best AR scope mount for you. These include the type of optic you are using, the intended use of your rifle, and your personal preferences.

Scope Diameter: The diameter of your scope’s tube (typically 1 inch, 30mm, or 34mm) is the first thing to consider. Ensure the mount you choose matches the scope tube diameter.
Mount Height: The height of the mount determines the eye relief and cheek weld. A mount that is too low or too high can lead to discomfort and inconsistent shooting. AR-15s typically require a higher mount to properly align with the shooter’s eye.
Material: Most high-quality scope mounts are made from aluminum or steel. Aluminum is lightweight and durable, while steel offers superior strength and resistance to wear.
Mount Type: There are several types of scope mounts available, including one-piece mounts, two-piece mounts, and cantilever mounts.

Types of AR Scope Mounts: A Detailed Overview

The market offers a variety of AR scope mount options, each with its own set of advantages and disadvantages. Understanding the different types will help you narrow down your choices and select the best AR scope mount for your application.

One-Piece Scope Mounts

One-piece mounts are generally considered the most stable and reliable option. They offer a rigid connection between the scope and the rifle, minimizing the risk of movement or shifting zero. These mounts typically feature a cantilever design, which extends forward to provide proper eye relief on AR-15 platforms. The monolithic construction enhances stability and reduces the potential for misalignment. This makes them a popular choice for precision shooting and applications where consistent accuracy is paramount.

Two-Piece Scope Mounts

Two-piece mounts consist of two separate rings that attach to the rifle’s receiver. While they are often more affordable than one-piece mounts, they may not offer the same level of stability. Proper alignment is crucial when installing two-piece mounts to avoid stress on the scope tube. They can be a suitable option for lighter recoil rifles or applications where extreme precision is not required. However, for serious shooters, the added stability of a one-piece mount is usually worth the investment.

Cantilever Scope Mounts

Cantilever mounts are specifically designed for AR-15 rifles. They extend forward from the receiver to provide proper eye relief when using a scope. This design is necessary because the AR-15’s receiver is relatively short, and a standard scope mount would position the scope too far back for comfortable viewing. Cantilever mounts are available in both one-piece and two-piece configurations. When choosing a cantilever mount, ensure it provides sufficient forward extension to achieve the correct eye relief for your specific scope and shooting style.

Quick-Detach (QD) Scope Mounts

Quick-detach mounts allow you to quickly and easily remove and reattach your scope without losing zero. This can be useful if you need to switch between optics or if you want to remove your scope for storage or transportation. QD mounts typically feature levers or locking mechanisms that allow for tool-less removal and installation. However, it’s important to choose a high-quality QD mount from a reputable manufacturer to ensure reliable zero retention. Cheaper QD mounts may be prone to shifting or loosening, which can compromise accuracy.

Material Matters: Aluminum vs. Steel

The material used in the construction of an AR scope mount significantly impacts its durability, weight, and overall performance. The two most common materials are aluminum and steel, each offering distinct advantages and disadvantages.

Aluminum Scope Mounts

Aluminum is a popular choice for scope mounts due to its lightweight properties and excellent strength-to-weight ratio. Aluminum mounts are typically made from aircraft-grade aluminum, which is known for its high strength and corrosion resistance. They are ideal for shooters who prioritize weight savings without sacrificing durability. Aluminum mounts are also less prone to rusting than steel mounts, making them a good choice for use in harsh environments. However, aluminum is not as strong as steel and may be more susceptible to damage from extreme recoil or impact. An AR scope mount made of aluminum is a great choice for most shooters.

Steel Scope Mounts

Steel scope mounts offer superior strength and resistance to wear and tear. They are typically heavier than aluminum mounts but can withstand significantly more recoil and abuse. Steel mounts are a good choice for high-powered rifles or applications where maximum durability is required. However, steel is more prone to rusting than aluminum and may require more maintenance to prevent corrosion. If you anticipate subjecting your rifle to heavy use or harsh conditions, a steel scope mount may be the best AR scope mount for you.

Key Features to Look For in the Best AR Scope Mount

Beyond the type of mount and material, several key features can distinguish a great AR scope mount from an average one.

Precise Machining: Look for mounts that are precision-machined to ensure a tight and secure fit with your scope and rifle.
Secure Clamping Mechanism: The clamping mechanism should provide a strong and consistent grip on the scope tube without damaging it.
Proper Eye Relief: The mount should allow you to achieve the correct eye relief for your scope and shooting style.
Durable Finish: A durable finish, such as anodizing or Cerakote, will protect the mount from scratches and corrosion.
Reputable Brand: Choose a mount from a reputable manufacturer known for producing high-quality optics accessories.

Installation Tips for Your AR Scope Mount

Proper installation is crucial for ensuring the accuracy and reliability of your scope mount. Follow these tips for a successful installation:

Read the Instructions: Always read and follow the manufacturer’s instructions for your specific mount.
Use the Correct Tools: Use the correct tools, such as a torque wrench, to avoid over-tightening the screws.
Apply Thread Locker: Apply a small amount of thread locker to the screws to prevent them from loosening over time.
Properly Align the Scope: Ensure the scope is properly aligned and leveled before tightening the screws.
Check Eye Relief: Verify that you have the correct eye relief before finalizing the installation.
