Where to Mount a Scope on an AR: A Comprehensive Guide
When it comes to enhancing the accuracy and versatility of your AR rifle, mounting a scope is a crucial step. The right scope can make a significant difference in your shooting experience. But where should you mount it? This guide will walk you through the various options and considerations to help you make an informed decision.
Understanding the Basics
Before diving into the specifics of where to mount a scope on an AR, it’s important to understand the basics. An AR scope mount is typically a set of rings and a base that attaches to the rifle’s Picatinny rail system. The scope itself is then mounted to the rings, allowing you to aim and shoot accurately.
There are two primary types of scope mounts for AR rifles: the traditional one-piece mount and the modular two-piece mount. The one-piece mount is a single unit that includes the rings and base, while the two-piece mount allows you to separate the rings and base for easier installation and removal.
Top Mount vs. Bottom Mount
The most common mounting options for AR scopes are the top mount and the bottom mount. Each has its own advantages and considerations.
Top Mount
A top mount places the scope above the rifle’s barrel. This is the most popular mounting option for several reasons:
-
It provides a clear line of sight, allowing for better accuracy and faster target acquisition.
-
It keeps the barrel free from obstructions, which can improve cooling and reduce the risk of overheating.
-
It allows for the use of various accessories, such as flashlights and lasers, without interfering with the scope’s performance.
However, a top mount may require a longer scope to clear the barrel, and it can be more challenging to install and remove the scope for cleaning or storage.
Bottom Mount
A bottom mount places the scope below the rifle’s barrel. This option is less common but can be beneficial in certain situations:
-
It can provide a lower profile, which may be desirable for certain shooting environments or for concealment.
-
It can be easier to install and remove the scope for cleaning or storage.
However, a bottom mount can obstruct the barrel, potentially affecting cooling and accuracy. It may also limit the use of certain accessories.
Scope Mount Height
The height of the scope mount is another important consideration. The height of the scope mount affects the overall length of the rifle and can impact your shooting experience.
There are several factors to consider when choosing the scope mount height:
-
Barrel Length: A longer barrel may require a higher mount to clear the barrel.
-
Optic Size: Larger optics may require a taller mount to clear the objective lens.
-
Shooting Position: A taller mount may be more comfortable for shooting from a prone position.
It’s important to choose a scope mount height that provides a comfortable and accurate shooting experience for your specific needs.
Scope Mount Material
The material of the scope mount can also impact its performance and durability. Common materials include aluminum, steel, and titanium.
-
Aluminum: Lightweight and durable, aluminum is a popular choice for scope mounts. It offers a good balance of weight and strength.
-
Steel: Steel is the strongest material for scope mounts, but it is also the heaviest. It is often used for heavy-duty applications.
-
Titanium: Titanium is the lightest and strongest material for scope mounts, but it is also the most expensive. It is often used for high-end applications.
Choose a scope mount material that suits your needs and budget.
Scope Mount Compatibility
It’s important to ensure that the scope mount you choose is compatible with your specific AR rifle and scope. This includes:
-
Scope Mount Type: Ensure that the mount you choose is compatible with your rifle’s Picatinny rail system.
-
Scope Size: Ensure that the mount can accommodate the size of your scope, including the objective lens diameter and overall length.
