What is a Scope Mount?

A scope mount is designed to hold together a scope that you have chosen for your AR-556 rifle. This is also known as a scope base. The name alone is self-explanatory for its purpose. You can also mount scope rings to ensure that the scope itself is aligned properly and stays in place each time you fire your rifle.

Types of Scope Mounts

Obviously, not all scope mounts are created equal. So, it’s important to know which one is which while you’re looking through this list. Here are some scope mounts that are currently among the most popular choices among Ruger AR-556 owners:

One Piece

One piece scope mounts have long been a staple for many AR-style rifle owners. That’s because these types of mounts are proven to be tough and rigid like nothing else. Not to mention, they’re pretty simple to install and use. Plus, alignment won’t be much of an issue once you are able to mount a scope on your rifle.

Scope Rings

Scope rings have probably been around since the beginning of time and were often used by the AR-style users of ages past because they are reliable and rugged. Today’s scope rings may not be your father’s (or grandfather’s) from years ago. But they're lighter in weight and are quite cheaper than other types of scope mounts.

Rail Mounts

Picatinny or Weaver? No matter which rail you use, you’re going to need a mount that will accommodate it. Plus, you’ll need a scope that will also be easy to attach to the rail as well. The difference between the rails is spacing. That’s why it’s always wise to take some measurements before you buy a mount for a scope that you already have.

How to Choose a New Scope Mount

Finding a new scope mount will take some time and knowledge of what to look for. In fact, you should always find a scope mount that is much better in comparison to low-quality cheap models. If you’re a first-time buyer, we recommend that you follow this brief guide to help you find the mount that’s right for your AR-556. Here are a few things to consider based on what past buyers have suggested:


If you’re not an expert gunsmith, there’s a good chance that you’ll need a scope mount that won’t be complex to install. Most of the scope mounts you’ll see on the list you will be able to install in a matter of minutes. This means you won’t need to rely on a professional to install a scope mount on your rifle. This will save you a lot of time and money.


Of course, knowing what kind of materials are used for manufacturing a good scope mount is important. That’s because the materials used will determine the overall quality of the mount as a whole. Most gun manufacturers will elect to use either steel or high-quality aluminum. Both are proven to absorb a great deal of shock and recoil, allowing your scope to hold zero even after you fire more than a hundred shots.


Taking measurements of your scope will matter if you’re looking for a good scope mount because some mounts will be suitable for 30mm scopes, while others will be able to handle one-inch tube scopes. Some mounts will even add on a couple of inches since there are a handful of scopes that give you a generous amount of eye relief.
