Most Manufacturers have climbed on the AR bandwagon, and many companies have now begun offering optics specifically geared towards this particular rifle/cartridge combination. Optics with drop compensation systems designed for the .223, special mounting systems and illuminated reticles are now par for the course and have become very desirable accessories for many shooting enthusiasts.

Red vs. Green Dot
Red dot sights are intended for short or medium range sighting. In general, they are not magnified or are magnified up to 1.7x. The lack of magnification allows the shooter to keep both eyes open, maximizing their performance in tactical simulations and situations. These are simple sights containing only a concave lens with a metallic coating that only reflects red light. The “dot” reticle that is projected upon a target is the reflection of a light emitting diode mounted inside the tube of the scope. The set-up allows you to see a red dot projected onto your target for quicker, more accurate acquisition.
Sight adjustments are simple to make. There are normally just two screws placed opposite to the coil springs for elevation and windage. Actual adjustment is made by operating the two screws to move the sight tube horizontally or vertically. Many manufacturers are trying to capture a larger market by offering different shape reticles, but these can degrade target acquisition. On the other hand, a larger dot does help some shooters who have an astigmatism. The size of the dot is stated in minutes of elevation, MOA, to helper shooter find the dot size they prefer before buying.
Green dot rifle optics are basically the same as a red dot sights. The main change is the color presented by the light emitting diode. Some shooting situations may be benefited by the use of green, but, generally speaking, the change in color is a shooter preference rather than a target acquisition issue. As with all rifle sights, both red dot and green dot optics are affected by a phenomenon known as parallax. Parallax is the ”error” that occurs when one of two vectors that are parallel is used as a reference for the other.
This is a problem for dot sights because they are designed to reflect the LED image down the center of the tube. So, if the weapon is held incorrectly, the shooter may view the dot near the edge of the tube. This means the dot will not actually be aligned with the correct point of aim. Dot scope manufacturers attempt to account for this by using a concave reflecting lens, but, unfortunately, the lens can only do so much and aim can be affected over greater distances.
Variable Optic Rifle Scopes
The AR-15 can be used in a variety of situations, so a versatile sight may be better for some shooters. That versatility can be delivered with a variable model. The goal of the 1-4x and 1-6x optics is to offer a shooter quick sighting up close and precision for distance shooting. Close up, 1x offers a huge field of view, while the 6x can offer a shooter pinpoint accuracy up to 600 yards. With versatility, why not use a variable optic sight in every situation? Weight.
Where dot models are always light-weight, even easy to use on a pistol, variable optic scopes are quite heavy. Some models can weigh in excess of one pound. You will also need a mount, adding another 7-10 ounces, putting the entire set-up close to two pounds. That doesn’t sound like a lot on the face of it, but an additional two pounds can be rather difficult to support while firing accurately.
Here are some important Features of a Variable Optics Rifle Scope:
To begin with, a quality variable optics rifle scope should feature capped turrets. You can only make adjustments to your sight after removing the cap. This does make sight adjustment a little more time consuming, but the turrets generally have a lower profile when they are capped, preventing them from snagging on your equipment. On the downside, some capped turrets lack a zero stop feature. If you do not intend to use your tactical rifle in the field, a low profile will not matter, so an adjustable sight with a zero stop may be fine for you.
Just keep the snag factor from the taller turrets in mind. A second feature to keep in mind is whether you want a sight with first focal plane(FFP) or second focal plane(SFP). A sight with FFP will keep the reticle consistent with target size. Many shooters want the reticle to shrink at 1x and grow as magnification increases, allowing the reticle size to remain stable in relation to the target. An SFP will keep the reticle size consistent at all magnifications.
Shooters can not range a target except at the manufacturers recommended magnification. An FFP is a better sight in most situations; however, they are cost prohibitive. The majority of these sights are more expensive than the rifles they are mounted on.
Long Range Fixed Scopes
Long Range Optics are used for Hunting, and with a tactical flair they are commonly used for law enforcement and military training.Long range tactical Optics are different than variable optics in the manner that they can be used at longer ranges, but they are are sometimes set at a fixed magnification. This means what you will typically see is something like the Nikon P-223 which is our absolute favorite model for distance, quality and price be set to a fixed magnification of say 3x. Some scopes let you adjust them between 1-6x, or 1-4x but you will see these state simply that they are 3×32, or 3×40. This doesn’t mean that the scopes are bad, it just means that you have a little less flexibility.
This is usually fine for most people as many shooters will pick up 2 different models – one for long range and another for short range. The advantages of owning two types of sights is obviously pretty simple. You get the flexibility of being able to slap on something for close range practices and situations (like the military) or you get to throw on a long range optic that will allow you to go target shooting or hunting on a regular basis.
The variable scopes do typically allow you to do both, but they usually come at a higher cost premium. Many shooters actually prefer to go this route just because it gives them flexibility with their other rifles as well. If you own an AR-10 and are out there shooting on a regular basis, finding two different types of optics is a great idea because you can have one for distance strapped to your AR-15 while the other at close range on your AR-10. Sounds like a win-win to me.
Best Long Range AR-15 Scope
Now that we’ve covered the difference between some of the different types of optics, let’s start with our favorite long range optics choice. We’d compare this scope to some other models, but there isn’t really a purpose unless you want a variable or red dot model. The Nikon P-223 is hands down the best scope for the money if you are looking for something you can slap on your AR-15 and go. There isn’t another model that can really hold a candle to it unless you pickup a variable scope, and even some of those aren’t as accurate as the P-223. It’s user friendly and very easy to zero in. Some variable models have their benefits but the P-223 is hands down one of the best optics you can buy and we highly recommend it. Check out the details below.
Nikon P-223 3×32 Matte BDC
If you are looking to place a sight on a rifle with a shorter barrel, such as the eighteen inch barrel of an AR-15, the compact Nikon P-223 3×32 Matte BDC Carbine Scope may be the answer for you. Designed with .223 Remington/NATO 5.56 rounds in mind, the sight performs well in 3-gun, tactical, or hunting situations.
Pros of the Nikon P-223 3×32 Matte BDC Carbine Rifle Scope:
- Reticle: with the trajectory of the .223 Remington/5.56 NATO rounds(with 55-grain polymer tips) in mind, the reticle provides a 200 yard cross-hair with markings at 400 and 600 yards.
- Elite optics: the optics are mulit-coated for additional brightness and target clarity. The sight is also nitrogen filled and sealed with o-rings to ensure that it is waterproof and fogproof.
- Turrets: the turrets offer ¼ MOA adjustment and have offer zero-reset.
- Economical: one of the better priced AR-15 scopes.
Cons of the Nikon P-223 3×32 Matte BDC Carbine Rifle Scope:
There is only one downside repeatedly mentioned about this sight: customer service from Nikon. Owners have stated that customer service reps are rude and some customers reported being hung up on. This can be avoided by ordering through online, bypassing Nikon’s customer service department altogether.
Best Tactical AR-15 Variable Rifle Scopes
Now that the basics are out of the way, we can move on to the important stuff, reviewing some of the top optics on the market. Below you are going to find our favorite variable models before we start jumping into the red dots, green dots and other close range AR-15 optics that are out there on the market today. This is a fantastic list to get you started and as you will see, many of these have a happy user base and have performed very well making them the best of the best in 2017 and going forward.
Simmons Predator Quest TruPlex
The Predator Quest TruPlex offers many of the features that you need to stay on target at any range. Some of the pros of this model are:

Cons of the Predator Quest TruPlex:
The Predator TruPlex is a solid sight in most situations. The only downside is that when you adjust the scope ”Up” your round will impact lower. This can be confusing since many other optics are the opposite. Since there is no industry standard, this is only a personal choice issue, not a manufacturer defect.
Bushnell AR Optics FFP
Bushnell may be the best known and most trusted name in shooting related optics. Every product offered by Bushnell provides shooters with optical precision, uncompromising performance, and rugged reliability.

- Battery door: the battery door is located in an adjustment knob. When you adjust that knob, the door opens. The signt should be manufactured with a way to lock the battery door.
Our Favorite Red & Green Dots
Below you will find an extensive list of the most budget friendly models in the green and red dot categories. Any of these optics will make fine choices for your tactical rifle. We will kick things off with the Redfield Counterstrike which is our favorite.
Redfield Counterstrike Red and Green Dot Sight
Redfield is a respected name in the optics niche and the Counterstrike Red and Green Dot sight is another solid performing choice offered by the company. This model is offered in a sleek black matte finish and has many of the features you want from a dot scope.
Pros of the Redfield Counterstrike:
- Aiming laser: the aiming laser is base-mounted and can be adjusted for elevation.
- Impact correction: shooters can make impact corrections is increments of ½ MOA.

- Reduced glare: the lens system is multi-coated to reduce glare and produce sharper images.
- Lightweight: the Counterstrike weighs less than 1.5 lbs.
Cons of the Redfield Counterstrike:
- Laser height: many owners have stated that the laser is mounted so low that it is blocked by the front sight of just about every model of rifle it is mounted on. This can be overcome by adjusting the mounting height with a riser, but that means you can not use the front sight as a back-up.
- Dot: several owners has said that the red/green dot is not sharp, often looking like a fuzzy halo more than a dot.
Vortex StrikeFire Red Dot Scope
When you need fast action and quick target acquisition, the Vortex StrikeFire Red Dot Scope could very well be the answer for you. This is a great lightweight scope that allows you unlimited eye-relief in every situation.
Pros of the Vortex StrikeFire:

There are two common complaints about this model. The first is that it does not power-up in cold weather; cold weather being defined as anything below 40 degrees. The second is with the on/off button. Many reviewers have said the button is either too touchy for practical use or so stubborn they have trouble turning the sight on. Either way, the sight becomes frustrating and a touchy on/off switch can cause you to drain the battery unexpectedly.
Leupold 111412 Mark 4 HAMR Rife Scope
The Leupold Mark 4 4x24mm High Accuracy Multi-Range(HAMR) rifle scope is designed to ensure mid-range precision and fast target acquisition in any lighting conditions. The combination of the HAMR and a red dot sight allow you to acquire any target at any range.

- No lens protection: the scope does not include lens covers, so it can be scratched. Quite risky for an expensive scope.
Aimpoint PRO-Patrol Rifle Optic
Aimpoint entered the rifle scope market making high-quality reflex sights. It didn’t take long for the company to realize that some shooters required a red-dot scope, thus the creation of the Aimpoint PRO (Patrol Rifle Optic).

Popular Budget Models
If you have a rifle with a carry handle there are a couple of popular low-cost options available to solve this particular quandary. The M-16 4x20mm from Barska comes with an integral mount to attach to the rifle’s carry handle. This features a drop compensation system that works in 100 yard increments out to 500 yards. Another popular low-cost option is the BSA Tactical Weapon 4x20mm. In addition to an integral handle mount, this product features a compact design and ¼ MOA adjustments. The BSA is an economical fix for a tricky problem.
Popular Top-End Models
When it comes to outfitting your rifle with the more common Picatinny, or flattop, mount, there are literally dozens of popular models on the market these days. The flattop rifles present no problems when it comes to mounting or using any traditional optic, but many tactical rifle users choose to pick an optic that is tailored to their specific needs. For those who don’t mind loosening their purse strings there is the Leupold HAMR 4x24mm, which comes with an adjustable red dot reticle, an integral mount and 60 MOA of adjustment for those shooters that want to reach downrange. This piece of hardware to the realm of serious AR shooters, but for discriminating buyers the Leupold name ensures that the HAMR will deliver in terms of quality and durability.
For those who want to spend a bit less, the Burris Xtreme Tactical XTR 1-4x24mm (with Fastfire) is an interesting option to consider. This model features an integral mount, adjustable magnification and a tough housing. What makes the Burris Fastfire model a bit different from other AR choices is the addition of a separate red dot sight attached to the top of the optic for fast shots at close range.
Most Popular Tactical Model
Those interested in maximizing their value for their tactical rifle will find the Nikon M-223 1-4x20mm to be an excellent choice. This model is compact, comes with a lifetime warranty and has return-to-zero finger-adjustable turrets. Return-to-zero capability is especially handy with cartridges like the 233 Remington that require fairly large adjustments for long-range shooting. The return feature allows the user to turn any adjustments back to where they started without marking up the turrets or wasting time with arithmetic. The M-223 within the reach of most shooters and will save a lot of time out on the range.
If your rifle is going to be used more for varminting or small game hunting, there’s no reason not to choose an optic built for hunting applications. The Leupold VX-II 4-12x40mm is a fine choice for the shooter who wants a quality product geared towards varmint hunting. This particular model of Leupold offers all the built-in quality and ruggedness associated with the Leupold name.
Clarity and resolution are always good with Leupolds, and this model’s 4-12 magnification range means that you’ll be able to pick out small targets, like gophers, at longer ranges. Given the low recoil of most tactical rifles there is a tendency to skimp a little when it comes to choosing a varmint hunter, but a high-end rig like the Leupold VX-II will help to milk every last bit of accuracy out of the rifle. Spending a bit more upfront will lead to more fun in the field later on.
Many shooters are beginning to discover that the AR-15 lends itself particularly well to coyote hunting. The diminutive .223 cartridge packs enough punch to put these small canines down, but is easy on the pelt if you wish to turn a small profit from your outings. Generally speaking, any optic designed for basic big game hunting is the one to choose for a coyote rifle, and the Zeiss line of Terra optics makes for an economical, quality choice for the coyote hunter.
Both the 3-9 and 4-12 Terras will work for nailing down coyotes, and the prices on them are surprising low for Zeiss products. These models can be mounted very low on the .223 and have a slim profile that comes in handy, as coyote hunting is oftentimes more vigorous than varminting. Of course, the Terra line has all of the Zeiss quality that people have come to expect and comes with a very nice warranty. Lower in price than traditional Zeiss offerings, the Terra line represents an opportunity not to be missed.
If you’ve decided to get an AR-style rifle in a caliber more suited to big game hunting, like the 6.8 Remington or other available wildcat cartridges, then a model like the Burris Fullfield 30 3-9x40mm is the one for you. As its name implies, the Fullfield 30 has a 30mm tube which allows for a wider range of adjustment to accommodate the trajectory variations you’ll run into when switching uppers from caliber to caliber. The Fullfield 30 also has a pleasantly compact design that will keep the overall package manageable for brush hunting or whatever you find yourself doing.
Ruggedness, quality and an excellent make the Fullfield 30 a very flexible option that is hard to pass on. There are other 30mm tube models on the market, but the Burris represents the best balance between quality and price. Many of the new cartridges for these platforms require considerable flexibility in an optic and in the long run you’ll be happier getting a scope with plenty of flexibility built in.

It is not the least expensive option on the market, but it is designed for a lifetime of tactical use.
While there are many scope choices for today’s active shooters, these are our favorites that every tactical rifle enthusiast should be taking a look at when buying a now optic for their rifle. Not only are there companies not mentioned here that make AR-specific options, but the companies mentioned above have many additional models and configurations. Beyond this, many manufacturers now produce units that augment other models to increase magnification, add night vision functionality or supply a red or green dot. One of the great things that has come out of the proliferation of the ArmaLite tactical rifle is that optics choices have broadened, prices have dropped and the quality of AR-specific choices has improved. Much like finding the best mosin nagant scope, finding the right choice for your rifle can be a complicated process.
With our vast experience in firearm optics of every caliber, we are confident that any of these optics could be the best scope for your AR-15 rifle and that no matter what, you won’t go wrong by choosing any of them.
