What is the AR-10?

AR-10 (Source)

The ArmaLite AR-10 is a battle rifle first introduced by ArmaLite in 1956 and used an innovative straight-line barrel/stock design with composite and alloy parts.

This design resulted in a small arm that was over one-pound lighter than other infantry rifles of the day, and significantly easier to control in automatic fire.

The AR-10 is air-cooled, gas-operated, and fires the NATO standardized 7.62x51mm cartridge in a 20-round detachable box magazine.

While the original AR-10 was built in relatively small numbers over its production run, it was hugely influential in the development of the AR-15.

AR-10 Models

The AR-10 was originally designed for use by the paratroopers in the U.S. military, so it is supposed to be light and effective for survival. Let’s now take a detailed look at the AR-10’s design and what features it offers.

AR-10 Design and Main Features

Below are the main features and design aspects:

Firing Mechanism

In the AR-10, the gas travels from a port near the middle of the barrel through a steel tube back into the receiver.

Next, it enters a chamber between the rear of the bolt and the inside of the bolt carrier. After pushing the bolt carrier to the rear, the excess gas vents through holes in its side.

Zev Technologies - Ar-15 Forged Rifle 5.56 16" (Source)

The main advantages of this design are improved accuracy from the bolt carrier movement and the lightness of the gun.

The rifle also stays on target after being fired. The simplified construction and weight-saving design of the gas system, bolt carrier, and bolt-locking were ahead of its time when originally designed..

Sights

The rifle’s sights are mounted high, while the rear sight is contained in a carrying handle that also protects the cocking/charging lever.

Receiver

The AR-10’s receiver is made from aluminum to reduce weight and the bolt locks into the extension on the barrel instead the receiver.

Aero Precision - 308 AR M5 Lower Receiver (Source)

All production AR-10s are fitted with standard steel barrels, while the stock is made from a composite reinforced fiberglass with a core of rigid plastic foam. The handguard and pistol grip are also fiberglass.

What is an AR-15?


Colt - AR-15 A4 20" 5.56 X45 mm Nato Matte Black 30+1Rd (Source)

The AR-15 is one of the world’s most popular semi-automatic rifles. The AR modular platform has made it extremely easy to customize and convert for various purposes.

The AR-15 uses a 5.56x45mm M193 cartridge in 20 or 30-round magazines. Due to the extensive use of Mylonite for its furniture, the AR-15 is light and weighs from 5.5 to 8.5 lbs.

It has a cyclic rate of fire of 800 rounds a minute with a muzzle velocity of 3,200 feet per second to a maximum effective range of 600 yards. The AR-15 is around 39.63 inches long with a barrel length of 20 inches.

AR-15 Design and Main Features

Here are the main features and design aspects:

Size

The AR-15 is around 39” in length and has a barrel length of approximately 20”. It is lighter than the AR-10 due to its shorter length and use of lightweight plastics. An AR-15 weighs around 6 to 7½ pounds in most cases.

Caliber

The AR-15 can accept two ammunition sizes, the Remington .223 round and a NATO 5.56mm round.


Hornady - Superformance Varmint Ammo 223 Remington 53Gr V-Max (Source)

A normal size magazine for the AR 15 holds 20 to 30 rounds, but again there are several variants to this.

The advantage of the AR-15’s design is its high rate of fire, lightweight, portability, and toughness. In addition, it is modular by design, so parts can be easily swapped out and upgraded.

AR-15 Models

After Colt's patents expired in 1977, many other manufacturers started to produce and sell their own AR-15-style rifles.

Next, we’ll take a look at some of the most popular and widely used AR-15 variants that have become successful in the firearms market.

REC7 by Barrett

The REC7 is not an entirely new rifle, but consists of an M16 lower receiver mated to an upper receiver, both made from forged aluminum.

This gun is compatible with many of the accessories that work with members of the M16 family, too. The rifle uses a short-stroke gas piston mechanism, unlike the M16’s direct impingement mechanism.

REC7 by Barrett (Source)

This variant uses the new 6.8mm Remington SPC (6.8×43mm) cartridge, which is a roughly equivalent length to 5.56×45mm NATO ammunition.

The REC7 has a threaded barrel to allow muzzle attachments such as a silencer and employs a free-floating Daniel Defense rail system.

This rail system allows many military accessories such as a bipod, night vision devices, and combat optics to be placed on the rifle.

This version is ideal for tactical and military usage, with its single-stage trigger, Magpul enhanced trigger guard, and beveled magazine well for rapid magazine changes.

The upper receiver is flat-top with a Picatinny rail. The barrel is chrome-lined and fitted with an M16A2 flash suppressor, a six-position Magpul MOE buttstock, and pistol grip. It has the major advantage of being highly compatible with accessories for the M16.

Ruger SR-556

The Sturm, Ruger & Co. introduced their own AR-15 variant in 2009, the SR-556. They would later create a .308 AR-10 variant, the Ruger SR-762. The SR-556 uses a gas piston operation.

Since 2014, this model has been replaced by the AR-556, a variant that utilizes traditional direct impingement action and introduces a rear flip-up sight.

RUGER - SR 556 VARMINT RIFLE 20" 5+1 (Source)

In 2017, Ruger introduced the AR-556 MPR Multi-Purpose Rifle, which comes with a Magpul MOE grip, a Magpul MOE SL collapsible buttstock, a free-floating M-LOK handguard, a Ruger Elite 452 two-stage trigger, a nitride cold hammer-forged barrel with 1:8" twist 5R rifling, rifle-length gas system, and a Ruger muzzle brake.

This rifle has the advantage of using some very reliable and high-quality Magpul components, but the accessory range is not as extensive as for some other AR-15 variants out there.

SIG Sauer SIG516

The SIG516 is a semi-automatic, multi-caliber AR-15 clone for civilian and law enforcement markets. The law enforcement and military versions have selective-fire options: single-shot, three-shot burst, and fully automatic modes.

The 516 has a four-position gas regulator, allowing the user to choose the amount of gas directed to the piston.

What sets the SIG516 apart is the customization features that makes it ideal for tactical uses. The safety lever is on the left side, making it convenient to reach with the thumb of the shooting hand.

SIG Sauer SIG516 (Source)

The front gas block is railed to accept the front sight with a flip-up sight post. It is also equipped with an M16A2-style birdcage flash hider.

All SIG516 models, except the Marksman, have 16-inch barrels with a free-floating M1913 Picatinny rail and flip-up iron sights.

The 5.56×45mm NATO models accept AR-15 style box magazines, which come in 5, 10, 20, and 30-round variants. The SIG516 Russian variant uses magazines designed for 7.62×39mm AR-15-style rifles.

The SIG516 Marksman rifle is hammer-fired and has a two-stage trigger mechanism, while all others have a single-stage trigger.

Smith & Wesson M&P15

The AR-15 variant from Smith & Wesson has been in production since 2006. The M&P in the name stands for "Military & Police" and pays homage to the famous Smith & Wesson .38 Military & Police revolver.

The M&P15 is available in different configurations, including some chambered in 5.56mm NATO/.223 Remington, .22 Long Rifle, and 5.45×39mm.

The 16” barrels come with either a melonite-lined or chrome-lined 4140 steel rifling and 7075 T6 aluminum receiver with a hard-coat black anodized finish.

Smith & Wesson - M&P15 Sport Ii 5.56Mm 16 (Source)

The Standard model has an adjustable CAR-15 stock and comes with a 10-round or 30-round magazine.

The Compliant model is designed for the California market, has a CAR-15 stock fixed in the open position, and comes with 10-round magazines.

The Performance Center target shooting version has an 18-inch bull barrel threaded to take any AR-15/M16-style compensator, a free-floated forend, integral Picatinny rail system and ships with a 10-round magazine.

Review of the Best AR-10 and AR-15 Rifles & Accessories

Let's dive into the review:

Pros

  • Installation is super-easy
  • Fits quite nicely with most rifles
  • Allows for easy magazine release
  • Excellent durability and construction
  • Perfect for upgrading or building projects

Cons

  • Pivot pin may be a little tricky to put in
  • Some fitting may be required depending on the rifle
  • Some say the magazine release button is a bit too long

What Recent Buyers Report

New users were using this lower receiver for the purpose of upgrading or adding onto a building project. Either way, they were happy with the durability and even the installation process of the lower itself. Once they had the parts handy, they had no problem installing each one. One user said he was able to install his favorite trigger onto this lower without any issues and it still works to his liking. He said the lower receiver was an upgrade compared to his previous one, which was a factory default.

Why it Stands Out to Us

A lower receiver will obviously house some of the most important parts of your AR-10 or AR-15 rifle. But you want something that is solid and will manage to hold everything together. The thing is, you will need a trigger assembly, a magazine, and plenty of other parts to ensure that your rifle is running like a well-oiled machine. So if you are looking for a solid upgrade or are building a rifle from the ground up and need a lower receiver to ensure that it will be well-built and stable, then give this one a chance to impress. 

Who Will Use This Most?

If you are upgrading or building, this lower receiver will be great for any AR-10 or AR-15 in either situation. Once you add this on, along with the other parts that make it all work, you’ll be ready for your next hunting trip or range session. It’s solid in construction and won’t loosen up through so many rounds. This is guaranteed to make your rifle feel more rugged and beastly. If that’s what you’re looking for in your AR-15 or AR-10 rifle, why not invest in a quality lower receiver like this?

Bottom Line

The Aero Precision 308 AR M5 Lower Receiver is a must-have accessory that every AR-10 or AR-15 will need to ensure complete functionality. It’s tough as nails and will be super-easy to install. Once you tack this onto your rifle, you’ll definitely want to put it to the test at the range. And we can tell you right now that you won’t be disappointed. Don’t believe us? Add this onto your rifle and give it a try. 

Pros

  • Well-built and sturdy
  • Reduced recoil right out of the box
  • Easy to fire off, with no jamming or malfunctions
  • Excellent for varmint hunting and target shooting
  • Flash hider does a good job preventing any night-blindness

Cons

  • May be a challenge to load
  • Rear sight may obscure some targets at times
  • The trigger may be a little gritty to pull at first

What Recent Buyers Report

A lot of new users were quite happy with the rifle. Once fully loaded, they were able to fire off a couple of shots to knock down most of their varmint targets. One user said that with the help of some of his favorite ammo rounds, he was able to knock down varmint targets from a good 100 to 200 yards out, each with instant kill shots. He said the reliability of the rifle was top-notch and had no malfunctions or jamming to deal with. 

Why it Stands Out to Us

At five rounds, that’s as many as you need for a rifle that will be ideal for varmint hunting. Yes, you can hunt with a whole lot more than that. But five is sufficient for most hunters. Other than that, it packs a pretty good punch and is able to knock down a varmint target with ease. Just find the right kind of rounds and you’ll be in business each time you go out during the day or night to find those pesky creatures that will wreak havoc on your property. For those who hunt at night, the built-in flash hider is perfect so your position isn’t given away and is able to prevent any night blindness from occurring. 

Who Will Use This Most?

If you are a varmint hunter in search of a rifle that will be consistently reliable and deadly accurate, why wouldn’t you say yes to a rifle like this? This will reach out and touch something beyond 100 to 200 yards (maybe even more). Not only that, it will be one of the best rifles you can use for around-the-clock hunting. This might be your next favorite property management tool. And it might come in handy when knocking out the varmints or predators that dare come near your property or livestock.

Bottom Line

The Ruger SR 556 Varmint Rifle is perhaps one of the best varmint hunting rifles on the market. Whether you hunt during the day or in the dark of night, this rifle will certainly be a force to be reckoned with. Put this to good use and you will watch your varmint hunting success skyrocket right before your eyes. 

Pros

  • Tough as nails in terms of durability
  • Easy to load by hand or speedloader
  • Excellent reliability most of the time
  • Does an excellent job shooting all kinds of ammo types
  • Perfect for hunting and competitive shooting applications

Cons

  • May get a little hot at times
  • Magazine release may be a bit difficult at times
  • A few have reported some jamming with cheap ammo types

What Recent Buyers Report

A lot of new users say this rifle worked pretty good in most applications, including hunting and competitive shooting. The rifle was quick and easy to fire and the cycling was smooth and reliable. Accuracy-wise, most users were able to land shots with consistently tight groups at various distances. One user even said that he got some really accurate kill shots while hunting for whitetail deer. 

Why it Stands Out to Us

This rifle might be one of the best AR-15 rifles for both field and range shooting. If you want something that is well-built and will stand the test of time, this might be the rifle that you will have no problem investing in. It has 30 rounds that you can work with, giving you plenty of firing power to ensure that your targets are hit in all the right places. Whether you are in the heat of intense competition or when you are bearing down on a sought-after hunting target, this rifle will rise to the call of duty and make sure that you hit your shots quickly without any kind of jamming or malfunctions. Pull the trigger and take pride in your shooting accomplishments with this rifle. 

Who Will Use This Most?

This would be the perfect AR-15 rifle for those in search of something that will be best for range shooting or hunting, in general. Yes, you get accurate and reliable shooting out of the whole deal. And you get a rifle that is lightweight and well-built. So cheap and flimsy isn’t the best way to describe this rifle (because it really isn’t). But if you want a rifle that is affordable and delivers more than what you pay for a kind of performance, this might be exactly what you are looking for.

Bottom Line

The Smith & Wesson M&P 15 Sport II rifle is not built to disappoint. It was built to amaze those who are avid hunters or competitive shooters. You can fire off as many 5.56 NATO rounds as you want. But you can bet your bottom dollar you will get a performance that is superb no matter what the application. And since it’s well-built, expect this to last you quite a while. 

Pros

  • Lightweight and super-fast
  • Easy to feed in most magazines
  • Perfect for hunting and target shooting
  • Provides consistently tight shooting groups
  • Does a serious amount of on-impact damage

Cons

  • None

What Recent Buyers Report

Most new users were satisfied with these rounds and for a few good reasons. For one, these were super-fast when it comes to velocity. And once they hit the targets (varmint or paper targets), they easily break apart and leave a good deal of damage. For varmint hunters, they managed to get easy kill shots out of these rounds. One user said these were super-reliable and didn’t jam in his magazine compared to the cheap ammo he once used.

Why it Stands Out to Us

Hornady is perhaps one of the best names when it comes to ammo. And these rounds are no exception to the rule. They live up to the name of being the most reliable rounds on the market. Not to mention, they are lightweight and designed to go the distance and are really fast. If you own an AR-15 or AR-10 and dying to get your hands on some rounds that will leave consistently tight shooting groups and kill varmint targets instantly, you may find these rounds to be some of the best in performance. The quality is outstanding and they will certainly leave behind a good amount of damage in their wake. 

Who Will Use This Most?

These are the best rounds you can find for varmint hunting. Why are they the best? One, they are quite fast. Two, they break apart easily and leave nice-sized wounds that will kill varmint targets instantly. That would be better than letting them suffer slowly (and it’s the most ethical way to hunt, for what it’s worth). If these rounds are checking off boxes of must-haves on your list, you know that these are the best choice for you.

Bottom Line

The Hornady Steel Match Ammo is the best choice for most varmint hunters today. Especially when they are looking for accuracy and easy kill shots for their AR-10 or AR-15 rifles. You will be amazed by how fast and lethal these rounds can be once you fire off a good number of them on your next hunting trip. 

Pros

  • Super-fast velocity
  • Consistently tight shooting groups
  • Leaves a good amount of damage on impact
  • Clean, consistent shooting in most applications
  • No accuracy issues at ranges between 200 to 400 yards

Cons

  • None

What Recent Buyers Report

A lot of new users were in search of a round that would be excellent for mid-range target shooting and also for varmint hunting, as well. These rounds were impressively fast and got to the target much faster than most rounds according to most users. They also said that on impact, these rounds would do a good amount of damage. One user even said that these rounds left a good kill shot wound in his varmint targets, killing them instantly almost 99 percent of the time. 

Why it Stands Out to Us

These rounds are lightweight and they travel a pretty good distance. They are the kind of round that will go a long way and hit your targets exactly where you want. These are the perfect rounds that can tear through varmint hide and flesh, delivering excellent knockdown power and instant kill shots. They won’t stand a chance once they are in the line of fire of your rifle. If you want rounds that will certainly go the distance and give you consistently tight groups every single time, these are what you need for your .223 AR-10 or AR-15 rifle. 

Who Would Use This Most?

If you are a varmint hunter or looking for a round that is perfect for mid-range target shooting, you will certainly buy these for the purpose of leaving a good amount of damage. These can travel fast and go the distance. There might be no other .223 round that can exceed such expectations like these. Load up your magazine with rounds like this and you will certainly make your .223 rifle an even greater force to be reckoned with. 

Bottom Line

The Hornady Superperformance Varmint .223 Ammo might just be the best possible choice you can find for rounds when it comes to accuracy and making sure that your varmints are knocked down and killed instantly. These rounds are second to none, according to a handful of users. And who would beg to differ since it’s got a good amount of velocity and hit power to boot?

Pros

  • Easy to install
  • Super-tough and really durable
  • Fits on most Picatinny and Weaver rails
  • Allows for excellent accuracy and precision
  • Excellent for the purpose of backup sights in case your primary ones fail

Cons

  • May get loose sometimes
  • May be tough to deploy at times
  • Could be large enough to obscure some targets

What Recent Buyers Report

A lot of new users were looking for a nice backup sight that would work in the event of their primary sights somehow failing them. They found this sight to be really easy to use for the purpose of precise and accurate shooting. One user said that by the time he was finished installing this, he wanted to fire off about 100 rounds at the range to test it out. He certainly was not disappointed when he wound up shooting consistently tight shooting groups at various distances ranging from 100 to 200 yards.

Why it Stands Out to Us

This sight is made from high-quality aircraft aluminum. If you haven’t known by now, it’s probably the toughest type of aluminum you can find. It’s super-easy to install this sight that will be deployable when you need it the most. While it isn’t designed to be a primary sight, it gets the job done in case you need it for those situations where you need to take a shot. Your failing primary sights shouldn’t stop you from doing so. If you want a sight that will work for AR-10s or AR-15s, you’ll want to give one a chance.

Who Will Use This Most?

This will be an excellent sight for many rifle users that want something that will tide them over prior to replacing failing sights. Yes, it’s at the right size to fit on most rifles. And it will allow for precise shooting in both hunting and target shooting applications. If you really want to keep your shooting groups tight, even when you’re not relying on primary sights, these might be the best ones you’ll want.

Bottom Line

If you want something that will help you keep shooting those accurate shots, the HQ Issue Offset Sight Set might be of service for your rifle. Whether you are hunting or target shooting, it’s the kind of sight that will make sure it will keep delivering accuracy to your shots, even when your primary sights won’t get the job done. It’s not only solid in construction, but it can withstand multiple amounts of shock from gunfire. No other sight could ever come this close when it comes to toughness. 

Pros

  • Easy to load
  • Provides excellent firing power
  • Little recoil right out of the box
  • Perfect for target shooting and hunting
  • The magazine is super-tough and durable

Cons

  • None

What Recent Buyers Report

This rifle was a hit with most users that were hunters and target shooters. They said this was a powerhouse that was able to shoot consistently tight shooting groups at targets ranging from 100 yards and beyond. One hunter said that even through 1000 rounds, his shooting groups were super-tight and showed no signs of changing any time soon. He also added that the rifle was consistently reliable and not once did it jam on him.

Why it Stands Out to Us

This rifle is a highly-functional rifle that can be used across so many applications. But what really makes this stand out is the overall durability. Not to mention, it’s easy to fire and the cycling is smooth and reliable. So it will give you a good amount of power to work with while you are spending the day out in the range or out in the field. You get accuracy, dependability, and quality all in one package. If you are looking for an AR-15 rifle that will be a lot of fun to fire off (and not spend an arm and a leg in the process), this is probably the best possible option for you. 

Who Will Use This Most?

This would be an excellent AR-15 rifle for those looking for a newbie-friendly rifle for target shooting and hunting. It fires pretty well and is not so intimidating in terms of gunfire. That’s because you’ll have less recoil to work with thanks to the built-in muzzle brake. It’s solid in construction and reliable in function. Why say no to a rifle like this if you’re dying to fire one for the first time?

Bottom Line

The Colt AR-15 A4 is a rifle that you can have a ton of fun with the second you pull the trigger. You’ll have plenty of rounds at your disposal in one magazine (and if you have extras, that’s even better). This will certainly be one of the best AR-15 rifles you can depend on. Who knows? You might not even need to upgrade to an even better model. At the price it’s going for, it’s affordable and a steal of a deal. 

AR-10 vs. AR-15 - Similarities and Differences

Now that we’ve looked at the various models and variants of both these rifles, let’s examine the differences and similarities between them.

Keep in mind that the AR-15 is a successor of the AR-10, and incorporates many of the successful design elements that field-tested AR-10s provided.

AR-10 vs. AR-15 Differences

Here are the main differences:

Caliber

The primary difference between the two is that an AR-15 is bored in 5.56/.223 and an AR-10 is bored in 7.62/.308.

Hornady - Superformance Varmint Ammo 223 Remington 53Gr V-Max (Source)

VS

Hornady - Steel Match Ammo 308 Winchester 155Gr Hpbt (Source)

The heavier ammo of the AR-10 makes it harder for troops to carry large amounts, but for big game hunters, it is better to have a large caliber like 7.62mm rifle. The AR-10 makes it easier to bring down large game.

Size

The AR-15 is about 3’’ shorter than the AR-10, making it more useful for tactical purposes. The AR-10 is 35.5" when collapsed and 39.5" when extended, while the AR-15 is 33.3" when collapsed and 36.6" when extended.

Weight

In order to withstand the forces of the heavier caliber in the AR-10, the overall weight of the AR-10 is 8.5 lbs., which is heavier than the AR-15, at 7 lbs.

Magazine capacity is reduced in the AR-10 because of the larger cartridge as well. Twenty-five rounds is the capacity of the AR-10, compared to the 30-round capacity of the M-15.

Rifling Rate

The modern commercially available AR-10 is chambered for the 7.62x51mm (.308 Win) and features a 16″ barrel with a right-hand twist at a rate of one twist per 11.25-in.

Compare this to the M15TAC16, which is the ArmaLite 5.56mm (.223) Tactical Rifle. It also comes with a 16″ barrel but has a right-hand twist at a rate of one twist per 7-in.

AR-10 vs. AR-15 Similarities

For starters, AR-15s and AR-10s are extremely similar weapons. They function in very similar ways, are built on similar frames, and have some similar parts.

Size

Both rifles have barrel lengths of 16 inches. Both rifles are light enough to be carried around by people of any size and strength.

Mechanism

The AR-15 employs the same direct gas impingement operation as the one used in the AR-10s but comes with a few more developments compared to its predecessor.

Rate of Fire

The AR-15 can shoot 800 rounds per minute with a muzzle velocity of 3200 FPS being realized to a maximum effective range of about 600 yards.

Meanwhile, the AR-10 has an impressive cyclic fire rate of about 700 rounds per minute with a 2,772 FPS muzzle velocity.

Top Pick Between AR-10 vs. AR-15

If you’re looking to get the best accuracy and power at long distances, the AR-10 may be your best bet.

If you truly need the extra power and accuracy at the range or need something that’s going to impart the maximum amount of force to a target at any range, the AR-10 may be the better choice.

Thanks to its longer range and the stopping power of the 7.62mm ammo, the AR-10 is preferred by law enforcers, especially snipers.

However, not everybody needs that extra range or stopping power (or the extra expense). The AR-15 is well-suited for home protection, varmint, and other small game hunting, and even security and public protection duties.

VS.

Colt - AR-15 A4 20" 5.56 X45 mm Nato Matte Black 30+1Rd (Source)

The advantages of the AR-15 are its versatility, easy availability, access to ammo and parts, and the fact that it has lighter recoil, is cheaper to shoot, and easy to maintain compared to the AR-10.

You can go to any gun store or even your local retailers and buy ammo for your AR-15. In emergencies, you can rely on finding ammo, parts, magazines, accessories, and other copies of the rifle itself.

If we were to choose one, we’d pick the AR-15 for its easy availability of ammo and parts, and the lighter ammo and portable size which make it easier to carry.

Conclusion

While both the AR-10 and AR-15 are historically significant rifles, the AR-10 became the forefather of the hugely popular and influential AR-15.

We’ve covered above the similarities and differences between the two guns, so you know how to distinguish between them.

If you’re considering a rifle for big game hunting or need plenty of stopping power in tactical and law enforcement usage, the AR-10 is your gun.

But in case you want a reliable, light-recoil, semi-automatic rifle with great accuracy, go for the AR-15, because ammo for the AR-15 is easy to come by and the aftermarket parts are plentiful and of high quality.
