Buyer's Guide

Buyers Guide: Selecting the Best AR-15 Scope Mounts for Your Gun

There are certain to be a few questions that come up if you're new to scope mounting. As a result, we've put up this step-by-step guide to ensure you have all the information you need before making a purchase. When it comes to choosing a rifle scope mount, you'll know precisely what you're looking for and be able to make an informed decision.

AR15 Scope Mounts

Why a Better Scope Mount Is Worth the Money

What's the point of spending money on a piece of equipment that you already have? In order to answer this question, you only need to look at the scopes that come with mounting rings. It makes sense, given that the scope you're acquiring is the most important consideration. The mounting rings are an afterthought when you're looking at the scope's specifications, but that's a mistake.

Investing in a cheap scope mount will result in your scope frequently losing zero after a few rounds of shooting. Because of this, your round can fly wide when you need it the most. That's one less thing you'll have to worry about if you invest in a high-quality scope mount. A scope mount is very necessary if your scope lacks mounting rings; this is the only way for you to utilize your scope

Mounting Your Scope Mount

Mounting your mount can sound like an oxymoron, but it's necessary. Picatinny rails on a rifle are compatible with the majority of the mounts listed here. Your weapon should be fine, as long as it is equipped with this type of ammunition.

However, weaver and dovetail rails are also common rifle mount types, so before making any purchases, be sure to check what's already on your rifle.

Check to Make Sure It Fits

Make sure that your scope mount is compatible with your rifle, as well as the scope itself! It's not a surprise that you'll need to check the rings' compatibility with your scope. One inch and 30 millimeter are the most common ring sizes, however there are many others. As long as you know your scope's measurements, all you need to do is choose the correct mount for your scope. You're in luck if you're looking for Vortex Optics scopes because they come in both small and large sizes. Some people require a scope that is compatible with the rings. Finding your scope and then purchasing a high-quality mount for it are the two steps we suggest. There are no limitations on scopes when you don't have to be constrained by a certain mount.

Tools You Can Use To Mount Your Scope Mount

The fundamentals of scope mounting remain the same whether you are utilizing a one-piece cantilever mount on the AR or standard bases and rings on a bolt-action rifle. Some important tools are required before the riflescope can be installed. Regular tools can harm the optic, thus we recommend that you use the following instead:

  • Because it can be used on many various firearms, the Hex Bit Tool is a great item to have on hand. Buying The Gun Tool from Real Avid is an option if you don't already own one. Bits and wrenches that can be used on weapons are included with the gadget.
  • In order to secure the scope mount to the AR15 platform, the Torque Wrench must be used.
  • It comes with two sets of rings to accommodate Picatinny Weaver Rails and a forward-reaching double ring.
  • A bubble level is a must when installing a scope or handgun sight since doing so without one will result in inaccurate installation. When mounting a scope, you must ensure that the optic is perfectly level.
  • Before installing the scope, use rubbing Alcohol and Cleaning Patches to thoroughly clean all components.
  • Resting Gun or Shooting Rest If you have the money, invest in a shooting rest so that you may test the accuracy of the scope you've fitted on your rifle. They may be purchased at a reasonable price for both rifles and pistols.
  • These are mostly household items that you probably already have on hand. Shooting rests are optional, but they make a huge difference when it comes to the installation of your rifle. Make sure you've got everything you need before reading on.

What to Consider Before Buying a Scope Mounts

It doesn't matter whether everything fits perfectly if it isn't the greatest option for you. When it comes time to choose your new scope mount, there are a few extra considerations that must be made.

AR15 Scope Mounts


While flush fittings provide a few advantages, extended fittings have a few disadvantages as well. To begin, we'll begin with the good. Eye relief is improved since the scope is moved higher up the rifle. Having too little space between your eye and the scope might result in your scope slamming into you in the face.

More eye relief is usually a plus, but you'll need a scope with enough magnification to make up for the extra distance the mount introduces. Your scope's magnification depends on how near you are to it, and this distance changes depending on the scope in question. When purchasing a 2′′ extended mount, make sure that your scope has adequate eye relief to accommodate it.


It's important to have a warranty. A warranty is a guarantee from a manufacturer that the thing it is selling you will work as promised. People seek goods like Vortex Optics and American Defense rifle scope mounts because of this. You won't have to worry about replacing them in a few years once you get them. That means, despite the higher price tag, they're virtually always a superior long-term investment.


Ultimately, this is a matter of personal taste. Weight is an issue for some shooters, but for others, they want it to be as light as possible in order to avoid feeling it.

When in doubt about whether the weight will annoy you, opt for a lightweight choice. This way, you won't have to install the mount and connect your scope just to find out that you don't like it after the fact.


It's important to keep things simple while making modifications, and mounting that need equipment make the job much more difficult. It's not a big issue if you purchase a high-quality scope, but you still have to deal with this additional stress. That's why American Defense's mount, for example, is so popular. Adjustments may be made with a simple twist of the knob, making it easier than ever to install your mount.

However, the most essential thing to remember is that everything will stay where it is after you've made your edits. You don't want a scope mount that is constantly moving out of position, even if you don't need any tools to put it back.

Preferences in Style

It isn't uncommon for some shooters to desire a weapon that is both functional and visually pleasing. The good news is that scope mounts come in a variety of colors and designs, but you may have to spend extra for them.

When selecting what is important to you, you must be honest with yourself. You may have to pay a little extra if you want your weapon to match the rest of your gear.

Scope Tube

Determine the scope's mounting requirements before purchasing a scope mount. Choosing a non-compatible attachment will render it useless. This means making sure it doesn't seem too loose or too tight.

The diameter of the tube is the most important aspect in determining whether or not the mount will work with your rifle. 30 mm, 34 mm, and 1-inch are the most often used scope tube diameters, respectively. It is possible to alter some scope mounts. Several more whistles and bells are available to ensure compatibility with a wide range of scope tubes. To be on the safe side, go with the one that is made for the diameter of your scope tube.

Scope Height

The point-blank range and accuracy of firing are affected by the scope height. The point-blank range decreases with increasing height. Because of this, you'll need to adjust the scope's elevation setting. Make sure that the rifle's barrel or any portion of the scope doesn't come into direct contact with the scope. If the scope's centerline is nearer to the bore, it will be more precise in its measurements.

Consistent long-range shooting accuracy can only be achieved with a lower-mounted scope, which provides a more direct line of sight to the barrel. The rifle's lifespan is affected by the scope's height. The more torque and force applied to the recoil, the higher the scope. The sight of a powerful rifle can be damaged or worn out quickly.

Scope Length

Adjustable lengths are common among the top scope mounts on the market today. Before purchasing a scope mount, you must determine your eye-level. Eye relief and mount compatibility are factors to consider while determining scope length. Before making a purchase, it is essential to speak with a representative from the company.


Ensure that the scope mounts are constructed of high-quality materials before purchasing them. This is critical to the product's long-term viability. Different materials are used to make scope mounts. Hardened Aluminum, hardened steel, zinc alloy, and other alloys of Aluminum are the most often used materials.

Solid steel and high-grade aluminum are the ideal materials for scope mounts since they are extremely sturdy and do not add much weight to your rifle. Remember that steel is heavier but more durable than aluminum if you have to pick between the two. Aluminum is very resistant to rust and corrosion.

Mounting System

If you have a variety of rifles, you must take into account the mounting method before making a decision. Detachable or fixed? The mounting method will let you make your choice.

Fixed Mounting System

Shooters who want to permanently put their accessories on their guns should choose for this sort of mount. You don't have to take it apart to damage scope parts with a fixed installation. It is more durable and lighter than the competition.

Detachable Mounting System

For some gun enthusiasts, having many weapons is a way of life. A removable mount mechanism will save them a lot of money. It features quick-detach levers and is made to be removed quickly.


The rails that the mounts employ, like the mounting technique, are crucial when selecting an attachment. Easy to install and long-term durability are all factors to consider here. Weaver rails or Picatinny rails are your only options.


The Weaver rail is the most popular choice among shooters due to its ease of removal without removing the base. Reattaching is just as simple, and the precision is preserved. Crosswise recoil slots are carved out in the flat 7/8-inch base the majority of the time.

Picatinny Rails

The base slots on picatinny rails are broader than those on weaver rails. If you have a weaver base, you may still use Picatinny rings, but the Picatinny rings will be wider.

Final Thoughts

If you don't know what you're looking for in a rifle scope mount, it might be a daunting endeavor. This buying guide should have alleviated some of your concerns and provided you with the assurance you require to make your next purchase.

As good as some other rifle scope mounts are, these are some of the finest!


How high should a scope be mounted on an AR?

Generally speaking, the lower the weapon's height, the more effective it will be. Instead of going low, try going mid. If you're unable to go medium, then you should try to get high.

How much clearance do you need between the scope and the barrel?

No worries if the scope isn't touching the barrel. It's fine to have a 6mm clearance, but it's a little too tight. There isn't much difference if you raise the scope by 3 millimeters, but you are the deciding factor.

Does scope height affect accuracy?

It is widely believed that the height of the scope has an impact on the precision of your shot. If you're consistent in your rifle setup, it might have a larger impact on your accuracy than the scope height.

Will any scope work on AR 15?

When purchasing a sight for your AR 15, there are numerous things to keep in mind. Choose the one that has the features and specs you desire. On the reticle, which amplifies the image, the scopes might differ. Many manufacturers employ a variety of reticle options on their scopes so that you may select the one that best suits your needs.

What size scope mounts do I need?

The most common scope mounts on the market are 30mm and 1 inch.The size you require is determined by the diameter of the scope tube. When using a scope on a lower caliber rifle, you don't need a larger optic. Before you buy one, think about what you want to do with it.

Do I need a 20 MOA scope mount?

Only a few applications necessitate the 20 MOA base. A shooter will lose elevation if he or she sets the elevation dial on a scope for ranges that are longer than the target. The average distance is about 600 yards.

It all depends on the firearm and its intended use. When using a flat cartridge, the scope is usually unable to dial out the additional 20 MOA of elevation needed to keep your target at 100 yards in sight. A range of 200 to 300 yards must be selected for firing the weapon. You need to know how much MOA of elevation travel a sight has before purchasing a 20 MOA scope mount because it is dependent on the rifle, ammunition, and scope combination.

Additional Information

AR15 Rifle Scope Mounts

AR15 Scope Mounts are a must have for any serious shooter. There are various types of mounted scope that can help you to enjoy your hunting or shooting experience at its best. The main purpose of an AR15 scope is to allow the hunter to hit his target from a long distance. This is why it is important to select the right type of mount so that the scope remains clearly visible to the hunter.

Quick detach mounts are handy when you frequently travel with your gun and finding it convenient to store your scopes separately. Since most a quick detach scope mounts are attached to one single eye relief, which is the shortest part of the rifle, this scope would ideally remain attached to zero on one scope. When it comes to recoil, these shorter eye relief scopes produce less recoil than standard models. In addition to zeroing, a quick detach mount allows the user to adjust the elevation, windage and focus by just removing one side panel. This is in contrast to more conventional larger sized scope that requires additional tools and accessories to use.

AR15 Scope Mounts produced by Aimable has been designed to increase both accuracy and durability of your rifle scope. There are two major types of mounts, namely the Full-auto PME and the semi-automatic larue tensioned. The designs include:

The fully-automatic PME is made up of steel tube that is securely clamped to the rail on the end of the rifle. This is the most recommended design among experienced shooters since it provides a very strong hold on the optics. This design makes it easier for the user to manipulate through different stages of shooting. One downside of this design is that it tends to produce a lot of heat which is uncomfortable during long shooting sessions. However, the heat generated by this design has been found to be significantly less than other designs of scope mounts.

The semi-automatic design is a bit more complex compared to the full-auto design. Since it requires the user to manually cock the weapon before using it, this requires additional actions like dischipping the bolt and loading the new one. However, most users find it to be a more comfortable type of mount as it provides a greater degree of zeroing accuracy. Due to its increased degree of zeroing capability, many users come across problems while using this kind of mount.

You can easily buy different scopes from different online stores at affordable prices. The different scopes include: Diamond Plate Scopes, Trijicon Minox Mini Tripod Mount, EOTech Mount, Bell Reflector Scopes, VXoom Mount, Black Oak Metering, Trijiconlance Spherical Scopes, Holosun Advanced Optics, etc. These are only a few of the scopes available online; others include Bushnell Elite Sight, Steiner Aptic, Steiner Ventia, etc.

Since there are numerous manufacturers, you have a wide variety to choose from. Before making a purchase, ensure that you identify with the right manufacturer for your AR15 scope. Some of the manufacturers include: Trident USA, Redding Diamond Plate, Hilti USA, Cockingham & Hinckley, Hornady, Windlass, Kwick, A.R.C., and so on. Each of these manufacturers offers different price points, and you must identify with the right price point for your specific needs.

There are two types of scope mounts that are used in AR15 rifles; the Quick Detach and the Hydraulic Quick Detach. The Quick detach is easy to use and provides a high level of accuracy. The advantage with the Quick detach is that it provides a positive force on the rifle, which increases its stability. The drawbacks of the Quick detach are that the eye relief is not as high, and the distance of the target is not that far away. With the exception of the Quick detach, all other scope mounts are relatively free standing.
