Best AR-15 Upper Receivers - Complete and Stripped  Featured

The AR-15 rifle has become one of the most popular firearms among gun owners thanks to its high precision, versatility, reliability, and lightweight built. The beauty and appeal of the AR platform is its modularity, which has many gun owners lining up to get one as part of their collection.

While there are many excellent pre-built ARs on the market, some prefer to take part in their own D.I.Y project by building and assembling various parts and accessories from ground up to create a unique custom build. If you’re building your own rifle, you definitely cannot miss out on one fundamental element needed, that is your upper receiver.

Types of AR-15 Upper Receivers

The receivers are the part on your AR-15 that lets you attach your favorite component. Typically, it comes in two parts: the upper and lower receiver. The lower portion is a serialized and legally controlled part which means you don’t need to get necessary paperwork from law enforcement or FFL while the upper receiver affixes to the lowers to hold all of the other parts. 

Some upper receivers come with all the parts already in place such as the barrel, gas block, charge handle, etc. or you can choose to get a stripped upper receiver, which you will then have the flexibility and freedom to install whichever parts you choose. 

Before we get into the best AR-15 upper receivers, here are a few kinds of upper receiver assemblies that you need to know:

A1 Upper Receiver 

The A1 is the earliest type of upper receiver with a 1:12 twist rate to enable accurate firings of up to 450 yards. The flip rear sight of the A1 upper is adjustable for windage while the rear sight also features both short- and long-range apertures. Generally, it comes with a light barrel profile, a fixed-carry handle, and forward assist.

A2 Upper Receiver 

Developed in the 1980s, the A2 features a rear sight that is not only adjustable for windage, but also for elevation as well. This type of upper receiver assembly has a heavier barrel compared to the A1 with rounded handguards and a 1:7 or 1:9 twist rate for faster shot velocity. Similar to the A1, it has a fixed-carry handle and forward assist.

A3 Upper Receiver 

This upper receiver assembly differs from the earlier two models such that it comes with a flat top configuration and a detachable carrying handle. Some A3 uppers even feature a “high-rise” configuration to provide a higher scope position. This type of receiver typically includes either a Picatinny or Weaver rail for gun owners to mount their preferred accessories. Likewise, this model also features a forward assist and rifle cuts in the feed ramp.

A4 Upper Receiver 

The A4 is pretty similar to the A3 in that it has a flat top upper receiver and a comparable overall design. However, unlike the A3, the A4 features an M4-style feed ramp to complement M4 barrels.

Factors to Consider when Choosing an Upper Receiver

Complete Upper Receivers or Stripped Upper Receivers?

When you’re on the hunt, you’ll notice that you get a choice of either purchasing a complete upper receiver or a stripped one. Complete upper receivers are a convenient all-in-one-package choice and they generally include the following AR-15 parts that play a crucial role:

  • Stripped Upper Receiver
  • Forward Assist
  • Dust Cover
  • Bolt Carrier Group (BCG)
  • Charging Handle
  • Barrel
  • Gas System
  • Handguard
  • Sights/Optics, or accessories

Getting a complete AR-15 upper receiver is the best choice for those who prefer a fuss-free installation as they can quickly pop the upper receiver onto their rifle and get going. 

A stripped AR-15 upper receiver, on the other hand, is basically just a hunk of metal that houses the other parts. Generally speaking, that is all you get when purchasing a stripped upper. However, there are a few models that come with a forward assist and dust cover installed, although a forward assist is not necessary for it to function. 

So then, you’ll need to decide whether you prefer to purchase everything in one convenient box or if you like to purchase parts separately and assemble them on your own to create a unique rifle that is just perfect for you. This is the best choice for those who enjoy a little D.I.Y project and like creating something a little different from the rest.

Materials

Aluminum

Most of the better AR-15 upper receivers you’ll see are made from aluminum since this material is lightweight, strong, and also affordable. However, there are different alloys used in the fabrication of these receivers and they are 6061 (T651) and 7075 (T651). 

The 7075 T6 is much stronger than 6061 counterparts and, obviously, this also means that it comes with a higher price tag. However, the 6061 T6 aluminum is much more corrosion resistant than the 7075 T6. But unless you’re getting a bare receiver, this should not carry too much impact on your decision.

Polymer

Upper receiver made from polymer is a good option for concealed carry pistols. With that being said, it’s not always the best idea to get a polymer lower even though they’re much cheaper since they’re much easier to break. Unlike pistols, AR-15 rifles will definitely introduce a lot more stress on your upper receiver, thereby generating a much higher chance of the polymer material breaking apart.

Titanium & Steel

Uppers made from titanium and stainless steel steel are very rare on the market and, frankly, there isn’t really much point in getting them. Of course, they’re much stronger than aluminum but they are also much heavier and come with a higher price tag. Some even feel that titanium and stainless steel are a little overkill as aluminum is more than strong enough to “bombproof” your AR-15 rifle.

Manufacturing Process for Aluminum Uppers

The three types of fabrication processes for aluminum uppers include cast, billet, and cold hammer forged.

Cast 

Casting is when molten aluminum is poured into a mold to create an upper receiver ready for final matching once it’s cooled. This is the most basic process, making them much cheaper than the others. 

However, since the aluminum is poured into the cast as a liquid, the final product tends to have a loose crystalline structure. This means that it has a weaker build compared to the others. In any case, this type of manufacturing process is still strong enough for the receiver to work safely without any concerns about a malfunction.

Billet 

Billet upper receivers are cut from a single piece of solid block pure aluminum which will then go through various milling processes before turning into a finished product. Since the material remains solid throughout the fabrication process, billet upper is much stronger than cast aluminum with a nicer finish. 

Billet upper also has the added benefit of offering manufacturers plenty of customization options, such as including various accessories and designs such as adding a skull-shaped magazine well, built-in trigger guards, and extra machining for better weight savings.

Forged 

This is the strongest and most common of the three kinds of upper receivers. Forced aluminum upper receivers are hammered into shape by compressive forces and machined to finish off. The compression of the material helps to increase its strength and creates a less refined tower. A forged aluminum is the best choice for AR-15 upper receiver groups if you plan on using it often and hauling it around with you everywhere.

Best AR-15 Upper Receivers – Complete and Stripped 

Now that we have gotten the basics over, let’s dive into the Best AR-15 receivers at different price points and their reviews.

1. DPMS Oracle

​Check For Best Price

This complete upper receiver comes pre-assembled with all the moving parts required and a 16-inch barrel. All you need to do is attach it with a mil spec lower receiver and a buttstock, and you’ve got yourself a complete upper receiver group. 

This upper is chambered in 5.56mm NATO match grade, meaning you’ll also be able to fire off a standard .223 ammunition with this barrel without any issue. Furthermore, this assembly even features a lightweight build and an anodized 7075 T6 aluminum receiver frame, making significant lightening cuts compared to other mil spec parts. However, the thinner and lighter material also means that there are reports from buyer that it is less durable. Hence, the Oracle is recommended for plinking rather than for rugged use out on the field. 

The Oracle features a direct impingement operating system meaning it will have the air travel through the gas block and gas tube into the receiver, where it will then power the BCG and auto-cycles the next round.

Coated with Teflon for smoother and easy operation, all parts on the receiver are also covered by DPMS’ lifetime manufacturer’s warranty. The barrel included is made with chrome-moly steel bore, but it is not chrome lined, meaning it is still susceptible to corrosion due to power residue, so you’ll need to make sure to clean and oil the Oracle thoroughly.

Pros

  • Pre-assembled for easy installation
  • Lightweight build
  • Can be used with 5.56mm and .223 ammunition
  • Teflon-lined receiver
  • Lifetime warranty
Cons
  • The barrel is not chrome-lined

2. Aero Precision M4E1

​Check For Best Price

The Aero Precision M4E1 is available in a number of variants, and we’ll be talking about several of them in our article today. To begin, we’ll first discuss the standard option which is the 5.56mm version that can also fire off .223 shot. 

Similar to the upper features discussed above, the 7075-T7 forged aluminum Aero M4E1 arrived pre-assembled, with a choice of either a 14.5-inch or 16-inch barrel extensions. The only thing you’ll need to add to it is a BCG and a bolt handle. Regardless of configurations, they each come with a Picatinny rail handguard and flash suppressor. 

However, you’ll need to take note of the 14.5-inch variant. This variant comes with the flash suppressor pinned and welded for it to be legal for civilian use. So you’ll need to check with your local law enforcement and national firearms act for further information. 

Getting back to the topic, the reason we’re fans of the Aero Precision M4E1 is thanks to its mid length gas system. Most AR-15 that have barrel lengths shorter than 18 inches utilize a carbine length system, meaning the gas port is 7 inches down its length. With the mid length system, you’ll get a gas port 9 inches down the barrel to make sure it provides just enough delay to reduce the occurrence of jamming.

Pros

  • Smooth, reliable cycling
  • Relatively easy to assemble
  • Can be used with 5.56mm and .223 ammunition
  • Mid length gas system
  • Lifetime warranty

Cons

  • Does not come with a bolt carrier group and CH
  • 14.5-inch variant have flash guard pinned and welded which may be a cause for legal concerns

3. Yankee Hill Machine Black Diamond Specter

​Check For Best Price

This upper receiver group comes fully assembled and ready to be installed on any mil-spec AR-15 lower. It is designed for 5.56mm, but also compatible with .223 rounds without any issue. As YHM’s flagship upper receiver group, you can be rest assured knowing they have strict quality control of all their products. 

The Yankee Hill Machine Black Diamond Specter features a 16-inch, chrome-lined barrel bore, a flash guard, and M4 feedramps attached at the end. The upper also comes with a Picatinny rail on top that extends continuously from the back of the receiver to the end of the handguard, with three additional rails you can find on the bottom and sides of the handguard.

The standard variant has a handguard length of 9.675 inches while the Black Diamond Specter XI version is 12 inches long. Much like the M4E1 receiver, this upper utilizes a mid length gas system in order to ensure reliable cycling. However, it does feature a low profile gas block to ensure there is more room for the handguards. 

Considering all its features and details which include four Picatinny rails on an extended handguard, 5.56mm chamber, a 16 inch barrel with a flash guard, and a mid length system all in an easy-to-assemble package, it is no wonder that this top-tier AR-15 upper receiver by Yankee Hill Machine also comes with a slightly higher price tag as optics planet prices it at $857.49 (at time of writing). 

Pros

  • Quick, easy installation
  • Smooth, reliable cycling
  • Available room for accessories
  • Lifetime warranty

Cons

  • May be expensive for some

4. Aero Precision M4E1 – .223 Wylde

​Check For Best Price

Engineered specifically for target shooters, this Aero Precision M4E1 variant is an all-new category that has a chamber that is finely machined for precise feeding of the .223 Wylde target shot. However, this upper receiver can also fire a standard civilian .223 cartridge, just not the 5.56mm ammunition. While the NATO bullets are much more powerful, the high pressure from releasing such ammunition can damage the chamber. 

The M4E1 upper includes either a 16 or 18 inch rifle barrel with a flash guard, a 12-inch handguard, mid length gas tube, and even a full-length Picatinny rail. Similar to the one we discussed earlier, this AR-15 upper receiver still requires a BCG and bolt handle. So you can either reuse the parts from your old receiver or get brand new ones from the market. 

Like all versions of the M4E1, this also uses a mid length system instead of the charter, carbine length one. This means you get to experience a smoother, more reliable cycling, which is essential in any match rifle.

Pros

  • Great for competitive shooting
  • Easy installation
  • Fits .223 Wylde rounds perfectly
  • Smooth, reliable cycling
  • Lifetime warranty

Cons

  • Does not include bolt carrier group and CH
  • Not compatible with 5.5 6mm ammo

5. Stag Arms 15L

​Check For Best Price

The Stag Arms 15L is a complete upper receiver group with all the required parts installed. While it does not feature a front sight block, this AR15 upper can be mounted on a standard, and mil spec AR-15 lower that pretty much everyone has and is chambered in 5.56 mm that is compatible with the .223 cartridges as well. 

Featuring an 18-inch stainless steel barrel and a matte black flash guard, the Stag Arms 15L also comes with an extended handguard measuring at 16.5 inches long, making it the best choice for accommodating a variety of stances. This complete AR-15 upper receiver group lets you hold the barrel close to the muzzle for maximum support. 

On top of the free-floating Stag 15L M Lok handguard that offers plenty of space, you’ll also find a full length Picatinny rail running from the back of the receiver to the end of the handguard. With a mid-length system, the 15L is sure to provide you with a smooth, jam-free operation. Although the upper is slightly on the heavier side with 7.1 pounds in weight, it does come in a durable and sturdy construction. 

Another great thing about this complete AR-15 upper receiver is that it is designed for left-handed shooters. So, if you’re a southpaw, you definitely won’t be able to find a better receiver designed for you than the Stag Arms 15L.

Pros

  • Quick, easy installation
  • Reliable cycling
  • Long handguard
  • Designed for left-handed shooters
  • Lifetime warranty

Cons

  • May be too heavy for some

6. Mega Arms AR-15 KeyMod

​Check For Best Price

Like most AR-15 receiver upgrades, the Mega Arms AR-15 KeyMod is chambered in 5.56 mm, meaning it has enough strength to handle high-pressure military bullets, yet still appropriately sized for civilian .223 rounds. 

While it is designed to mount on a standard mil spec AR-15 lower receiver and suppressor, this AR-15 upper still requires some assembly. The Mega Arms upper includes an ejection port door, barrel nut, wrench, dust cover door, and a forward assist button but does not come with a bolt carrier group and a charging handle. It also does not feature a barrel, which could be either a blessing or a curse. Some will like it as they get to pick their own barrels while some may feel that barrels are a pain to install. 

As the name suggests, the Mega Arms AR-15 upper receiver features a KeyMod handguard with a full-length Picatinny rail. Once assembled, the rail will run continuously from the back of the receiver right to the end of the 8 ¾ inch handguard.

Pros

  • High quality KeyMod rail
  • Handguard supports low-profile gas blocks
  • Freedom to pair with your preferred barrel
  • Lifetime warranty

Cons

  • Requires assembly
  • Does not include barrel, bolt carrier group, and a CH

7. Radical Firearms HBAR Radical

​Check For Best Price

Something a little different, this complete AR-15 upper receiver group from Radical Firearms is chambered for 7.62mm NATO cartridges instead of the typical 5.56 mm, meaning it packs way more punch. This also means that it gives you plenty of stopping power for a self defense weapon, but it does come at the cost of increased recoil and less readily-available ammunition. 

This AR-15 upper comes fully assembled and ready to be mounted onto a mil spec lower. However, you’ll still have to get your own bolt/carrier group and CH for this one. 

Make a note not to reuse your old bolt if you’re upgrading your 5.56 mm or .223 caliber AR, you should get a bolt that is designed to fit the 7.62mm NATO instead. 

Not only does the HBAR Radical AR-15 upper come with an 18-inch chrome-moly steel barrel, m4 feed ramps with takedown pin holes, and pre-attached flash suppressor, but you also get a 16-inch KeyMod handguard with a full length Picatinny rail with it. Featuring a Carbine-length gas tube, this complete upper receiver offers a direct impingement system.

Pros

  • More powerful than .224 and 5.56 mm caliber
  • Easy installation
  • Lifetime warranty

Cons

  • Does not include bolt/carrier group and a CH

​Check For Best Price

8. Sabre Defence AR-15 Forged Stripped

​Check For Best Price

This AR-15 upper receiver is the best option for heavy usage as it is able to take on a serious beating. Unlike most AR-15 upper receivers, this one is made of forged material instead of billeted from a metal block. This means it offers enhanced durability and reliability compared to a typical factory stock receiver. 

The flat-topped designed Sabre Defence AR-15 features chambers for the .223 Remington, meaning it is also suitable for use with the civilian .223 ammo. As the name suggests, this is a stripped receiver, so don’t expect it to come with any attachments. 

In fact, you’ll need to purchase and install all the hardware yourself, including the bolt carrier group, charging handles, forward assist button, M4 feed ramps, and the ejection port door. Needless to say, you should make sure you have all the necessary gears on hand. Otherwise, you may have to send it to the workshop to hire the services of a professional gunsmith for assistance. If anything, this is still a great model that meets the needs of people on a budget.

Pros

  • Can be paired with a variety of hardware and barrels
  • Made from durable, forged construction
  • Affordable

Cons

  • Rifle style feed ramps
  • Requires assembly

9. American Spirit Arms Side Charging

​Check For Best Price

If you need an AR-15 upper receiver that lets you chamber a round without losing sight of your target, then the American Spirit Arms Side Charging may just be the best choice for you. 

Additionally, this stripped upper receiver is compatible with just about any caliber that can be fired from the AR-15 platform, which includes the standard 5.56 mm, .223 caliber, 7.62 mm NATO, 6.5 Grendel, and even the 6.8 mm Special.

Similar to the previous one we discussed, this is a stripped model, meaning you’ll need to prepare your own hardware and assembly. However, you need to be careful with the bolt carrier in particular as this upper receiver requires a special notch cut on the side. With this in mind, you can opt to have American Spirit Arms to mill the bolt carrier for a fee, or you can also search for your own compatible part.

While it seems inconvenient, the main reason American Spirit Arms added this notch is to fit its CH, which is located on the side of the gun instead of at the back. This feature allows you to reload rounds into your AR-15 without needing to change position and lose sight of your picture.

Pros

  • Compatible with almost any AR hardware
  • Fits various calibers
  • Best for maintaining sight picture while chambering a round

Cons

  • Requires a proprietary bolt carrier notch
  • Significant assembly required
  • May be expensive for some

10. Bravo Company Flattop

​Check For Best Price

This is a complete upper receiver engineered with 7075 T6 Aluminum by Bravo Company and is engineered to support almost any caliber that is compatible with the AR-15. This means that you can use this with any readily-available ammo such as the 5.56 mm, .223 round, or even the 7.62 mm, .300, and 6.5 barrel for better stopping power. 

While it is labeled as a complete upper receiver and it does include the ejection port door, forward assist button and laser t marks for optics mounting, you’ll still have to provide your own bolt carrier group and CH. 

The Bravo Company Flattop AR-15 uppers feature vice-tight threading on the barrel extension to increase stability and eliminate any potential for wiggle. If you find that your barrel won’t thread, the company recommends you to try warming up the barrel extension with a hairdryer to get it to expand before installing. 

An alternative option to consider from Bravo Company is their BCM 11.5 Carbine Upper Group that features an M4 profile.

Pros

  • Fits several calibers
  • Compatible with almost any AR-15 hardware
  • Tight barrel fit

Cons

  • Requires assembly
  • Does not include bolt carrier group and CH

11. Bushmaster M4 A2

​Check For Best Price

This complete upper receiver and the barrel are nearly identical to the original M16 upper and it includes the barrel, handguard, bolt carrier group, and CH. All you have to do is to drop it into your mil spec lower receiver, insert the retention pins, and you’re all set to go out for shooting drills. 

What’s best about this kit is that it features a classic, M16-style design on an 11 ½-inch SBR barrel, which includes a bayonet mount near the muzzle. Those who are a fan of authentic military fear will absolutely love this upper receiver. It also features an iconic carry handle rear sight, tall front sight, and a comfortable polymer grip to make the M16 style so much more recognizable. 

Like any rifle barrel that is under 16 inches long, you should get government authorization to actually mount the Bushmaster M4 A2 onto your rifle. So, it is best to check with your local gun dealer about submitting paperwork to register an SBR. Or, you could attach a pistol grip only in order to ensure you get a legal AR-15 pistol that is in-line with your local state laws and regulations instead. 

Pros

  • Quick, easy installation
  • Comfortable polymer handguard
  • M-16 style bayonet mount

Cons

  • Requires SBR registration for rifle use

​Check For Best Price

12. Daniel Defense MK18

​Check For Best Price

The Daniel Defense MK18 AR-15 upper is chambered in 5.56 mm but can also accommodate .223 rounds. It arrives fully assembled and only requires a BCG and a CH before installation onto a mil spec AR-15 frame. The MK18 AR-15 upper comes with a rallied forend currently provided to the USSOCOM. 

The main feature of this upper receiver is its 1:7 barrel twice, which provides a much faster bullet rotation to help you improve your accuracy from a short barrel. Aside from that, the MK18 also includes a 10-inch handguard and a Picatinny rail for you to attach your accessories. 

The barrel on the MK18 is only 10.3 inches long and you’ll have to build it into an AR-15 pistol or get NFA authorization for an SBR if you want it on a rifle.

Pros

  • Easy installation
  • Tight 1:7 barrel for better accuracy

Cons

  • Does not include BCG and CH
  • Requires SBR registration for rifle use

13. Aero Precision M4E1 – .300 Blackout

​Check For Best Price

Despite the name, the Aero Precision M4E1 .300 Blackout is surprisingly not chambered for the .300 aac blackout round. Instead, this round offers higher stopping power compared to a standard .223 or 5.56 mm round but at the expense of reduced accuracy. 

With that in mind, this upper receiver is better suited for a top-tier short-range gun, perfect for home defense and combat purposes. 

The Aero Precision M4E1 .300 Blackout comes in three different barrel lengths assemblies: 8, 10, and 16 inches. Do take note that you’ll need to either build an AR-15 pistol or get NFA authorization for the 8 and 10-inch barrel.

Pros

  • Plenty of stopping power
  • Multiple barrel lengths available
  • Lifetime manufacturer’s warranty

Cons

  • Expensive ammunition
  • Does not include bolt/carrier group or CH

Conclusion

Whether you’re searching for the best AR-15 complete upper, or a simple stripped upper to upgrade your rifle, we hope that today’s article on upper receiver guide and review has presented you with enough knowledge and a wide selection of suitable stripped and complete upper receivers to fit your needs. 

One note is that stripped uppers are typically just a housing that you’ll need to prepare the forward assist button, ejection port door, BCG, flash hider, muzzle devices, carry handle, compensator, suppressors, brass shell deflector, and other internal components or other attachment you prefer separately. You will also need to prepare the necessary machine tools to assemble everything together. 

A stripped upper works to improve weight reduction for your AR-15 on top of improving its durability and reliability, but it won’t change its overall performance. Meanwhile, a complete upper receiver includes all necessary moving parts. This type of upper is obviously much more expensive, but it offers significantly more options. 

Overall, you’ll most likely notice that most of the uppers are from Brownells as our personal opinion is that they seem to always offer the best gun deals. But aside from Brownells, you can also consider manufacturers and companies such as Palmetto State Armory (PSA), American Tactical Imports, Lewis Machine Tool, and Rainier Arms. Generally, Brownells prices, Rainier Arms prices, and Aero Precision prices are pretty close range and competitive. 

Regardless of which listing you choose, always remember guys, you need to do enough research and check out comments from gun buyers/customers and their thoughts or suggestions. Reading through forums and ratings or watching YouTube videos will also help you out before making that purchase. 

Some upper receivers may be advertised with attractive capabilities and seem like the real deal but they may come with their own issues. Always take note that the best for someone else may not be the best for you. It depends on your own personal preferences and functionality.
