Best 300 Blackout Upper - Editor's Choice

What is 300 Blackout Upper?🤔

It is the upper receiver portion of an AR-15 rifle chambered in 300 AAC Blackouts. This caliber was created by Advanced Armament Corporation and Remington Arms Company as a way to make use of existing .223/5.56mm NATO magazines while still providing the capability to fire .30 caliber projectiles from a rifle.

300 Blackout Upper

Features🔔

When considering the features of a 300 Blackout upper receiver, there are several aspects to take into account. The best models typically possess the following characteristics:

☑️ The 300 Blackout cartridge performs optimally with shorter barrels, typically between 8 and 16 inches in length. The twist rate should ideally be 1:7 or 1:8, allowing for stable flight and accuracy with both subsonic and supersonic ammunition.
☑️ The gas system configuration can vary, with the most common options being pistol-length, carbine-length, and mid-length systems. The choice depends on your intended use and personal preference, but carbine or mid-length gas systems are often preferred due to their reliability and softer recoil.
☑️ A good upper should feature a high-quality handguard with a rail system for attaching accessories such as optics, lasers, grips, or lights. Keymod, M-LOK, and Picatinny rails are common options that provide versatility for accessory attachment.
☑️ Given the versatility of the 300 Blackout cartridge, it’s beneficial to have a muzzle device that allows for easy attachment of suppressors or flash hiders. Look for uppers that feature threaded barrels compatible with standard suppressor mounting systems.
☑️ A reliable and properly designed BCG is essential for the smooth functioning and consistent cycling of the firearm. Look for a high-quality BCG made from durable materials and properly treated for reduced friction and increased longevity.
☑️ The upper receiver can be made of various materials, including aluminum alloys such as 6061 or 7075. These materials offer strength while keeping the weight of the firearm manageable.

Major components of the upper assembly💡

When it comes to the upper assembly of an AR-15 rifle, understanding the key components is crucial for maintenance, customization, and troubleshooting. Here are the six major components you should be familiar with:

1️⃣ Barrel: It is a long, cylindrical tube that guides the bullet’s path when fired. It plays a vital role in determining accuracy and effective range. Threaded at the muzzle end, it allows for the attachment of muzzle devices like flash hiders or suppressors.

2️⃣ Upper Receiver: The upper serves as the main housing for the upper assembly components. It attaches the barrel, handguard, bolt carrier group, and other accessories. Equipped with a rail system, such as Picatinny or M-LOK, it allows for the attachment of optics and other accessories.

3️⃣ Bolt Carrier Group (BCG): It comprises several essential parts, including the bolt, carrier, cam pin, firing pin, and retaining pin. It handles loading, chambering, firing, and extracting cartridges. During the firing cycle, the BCG moves back and forth within the upper receiver.

4️⃣ Charging Handle: Positioned at the rear of the upper receiver, the charging handle is a lever used to manually retract the bolt carrier group. It enables the chambering of a round and the clearing of malfunctions. Pulling back the charging handle cocks the firearm and chambers the first round.

5️⃣ Gas System: This system regulates the cycling of the bolt carrier group and facilitates the chambering of a new round after each shot. With options like pistol-length, carbine-length, and mid-length, the gas system utilizes gas tapped from the barrel to operate the firearm.

6️⃣ Handguard: It surrounds the barrel and gas system, providing protection and a gripping surface. It acts as a heat shield and features attachment points for accessories like lights, lasers, or foregrips. Handguards come in various lengths and materials like aluminum or polymer.

How to assemble it?🛠️

Assembling an upper receiver for an AR-15 rifle requires careful attention to detail and adherence to proper procedures. Here’s a general guide on how to do this:

➡️ Gather the necessary components: Collect all the parts required for the upper receiver assembly. This typically includes the upper receiver, barrel, barrel nut, gas block, gas tube, handguard, muzzle device, forward assist, ejection port cover, charging handle, bolt carrier group, and any desired accessories.

➡️ Prepare the barrel: Install the barrel onto the upper receiver by aligning the barrel extension with the corresponding notch in the upper receiver. Slide the barrel into place until fully seated. Secure the barrel nut onto the upper receiver and torque it to the manufacturer’s specifications, ensuring proper alignment for the gas tube.

➡️ Install the gas block and gas tube: Attach the gas block to the barrel at the appropriate location, ensuring it aligns with the gas port. Secure the gas block in place using the provided screws or pins. Insert the gas tube into the gas block and route it through the barrel nut and upper receiver, aligning it with the corresponding hole in the bolt carrier group.

➡️ Attach the handguard: Slide the handguard onto the barrel nut, aligning it with any corresponding attachment points. Secure the handguard in place using the appropriate mounting system (e.g., screws, clamps, or a proprietary attachment method). Ensure the handguard is properly aligned and tightened.

➡️ Install the muzzle device: Thread the desired muzzle device onto the barrel, ensuring it is properly aligned and tightened. Use a crush washer or other appropriate method to achieve proper timing of the muzzle device if necessary.

➡️ Install the forward assist and ejection port cover: Attach the forward assist assembly to the upper receiver using the provided hardware. Install the ejection port cover assembly by sliding it into the appropriate slots on the upper receiver.

➡️ Insert the charging handle and bolt carrier group: Insert the charging handle into the rear of the upper receiver, ensuring it is properly aligned and secured. Slide the bolt carrier group into the upper receiver, aligning the charging handle with the channel in the bolt carrier. Ensure the bolt carrier group moves smoothly.

➡️ Check functionality: Cycle the charging handle and bolt carrier group to ensure smooth operation. Verify that the ejection port cover, forward assist, and charging handle function correctly.

FAQ🤓

What size barrel is best for 300 Blackout?

🔍 The choice of barrel size depends on your specific needs and preferences. However, there are some general guidelines to consider:

🟣 Shorter barrels (8-10 inches): Shorter barrels offer increased maneuverability and are well-suited for close-quarters engagements, home defense, or applications where compactness is a priority. They can also maximize the effectiveness of subsonic ammunition, which is commonly used for suppressed shooting.

🟣 Mid-length barrels (12-14 inches): Mid-length barrels strike a balance between maneuverability and ballistic performance. They provide good accuracy and velocity while still maintaining a relatively compact profile. This barrel length is versatile and suitable for a wide range of applications, including hunting and self-defense.

🟣 Longer barrels (16 inches or more): Longer barrels offer increased velocity, resulting in improved long-range accuracy and energy retention. They can be advantageous for hunting, precision shooting, or when engaging targets at extended distances. However, longer barrels may sacrifice some maneuverability.

📌 It’s worth noting that the 300 Blackout cartridge is designed for optimal performance in shorter barrels, particularly when using subsonic ammunition. Shorter barrels can provide better powder burn efficiency and help achieve consistent velocities with both subsonic and supersonic loads.

Does 300 Blackout use the same upper receiver?

😉 Yes, the 300 Blackout cartridge uses the same upper receiver as the standard AR-15 platform. This allows for easy interchangeability and compatibility between different calibers within the AR-15 platform.

🔷 The AR-15 upper receiver is designed to accommodate various calibers by simply swapping out the barrel, bolt carrier group, and magazine. This flexibility is one of the key advantages of the AR-15 platform, as it allows shooters to easily customize their firearms for different purposes or calibers.

🔷 When switching to a 300 Blackout upper assembly, you will need to ensure that you have the appropriate barrel, bolt carrier group, and magazine designed specifically for the 300 Blackout cartridge. These components are chambered and designed to handle the dimensions and pressures of the 300 Blackout round.

✔️ In summary, the upper receiver of an AR-15 can be used with a 300 Blackout setup by replacing the necessary components specific to the 300 Blackout cartridge while maintaining the same upper receiver.

Is a 10.5-inch barrel good for 300 Blackout?

🤓 Yes, it is a popular choice for 300 Blackout rifles. It offers a good balance between compactness and ballistic performance. Here are some considerations:

💣 Maneuverability: A 10.5-inch barrel provides excellent maneuverability, making it well-suited for close-quarters applications, such as home defense or use in tight spaces. Its shorter length allows for easy maneuvering and handling in confined environments.

💣 Suppressed Shooting: The 300 Blackout cartridge is commonly used with suppressors due to its subsonic capabilities. A 10.5-inch barrel pairs well with a suppressor, allowing for a compact and suppressed firearm. The shorter barrel length helps maintain a compact overall package, which is desirable when using a suppressor.

💣 Ammunition Performance: While shorter barrels may sacrifice some velocity compared to longer barrels, the 300 Blackout cartridge is specifically designed for optimal performance in shorter barrels. It achieves efficient powder burn and maintains good performance, particularly with shorter barrel lengths. This is especially true when using subsonic ammunition, where the shorter barrel can provide consistent velocities and reliable cycling.

💣 Ballistic Performance: While a longer barrel may offer slightly improved velocity and energy at longer distances, a 10.5-inch barrel still provides adequate ballistic performance for most practical purposes. The 300 Blackout cartridge performs well within typical engagement distances, making the 10.5-inch barrel a versatile choice.

What's the difference between 300 Blackout and 300 AAC Blackout?

📢 There is no significant difference between “300 Blackout” and “300 AAC Blackout” as they refer to the same cartridge. The terms “300 Blackout” and “300 AAC Blackout” are used interchangeably and refer to a specific rifle cartridge designed for the AR-15 platform.

💥 The cartridge was initially developed by Advanced Armament Corporation (AAC), thus the “AAC” designation in the name. However, the name “300 Blackout” has become more commonly used to describe the cartridge.

💥 The purpose behind the development of the 300 Blackout was to provide a versatile cartridge that could be used in standard AR-15 rifles while offering enhanced performance compared to traditional pistol calibers. It was specifically designed to excel in short-barreled rifles and to offer reliable performance with both supersonic and subsonic loads.

⭐️ In summary, “300 Blackout” and “300 AAC Blackout” are different names used to refer to the same cartridge, and both terms can be used interchangeably to describe this specific caliber designed for the AR-15 platform.

What parts are compatible with 300 Blackout?

🟪 The 300 Blackout cartridge is designed to be compatible with the standard AR-15 platform, with certain specific components required for proper functioning. Here are the key parts that are compatible with 300 Blackout:

🧩 Upper Receiver: The upper receiver of an AR-15 is compatible with 300 Blackouts. It serves as the foundation for the upper assembly and houses various components such as the barrel, bolt carrier group, and handguard.

🧩 Lower Receiver: The lower receiver, which includes the trigger group, magazine well, and stock attachment point, is also compatible with 300 Blackout. The lower receiver is where the magazine is inserted and the trigger mechanism is housed.

🧩 Bolt Carrier Group (BCG): The BCG is responsible for chambering, extracting, and ejecting cartridges. A specific 300 Blackout BCG is required, as it has a modified bolt face to accommodate the larger diameter of the 300 Blackout case.

🧩 Magazines: The standard AR-15 magazines can be used with 300 Blackout, but it’s important to note that specific magazines designed for 300 Blackout are available. These magazines are modified to optimize feeding and reliability with the shorter and larger-diameter 300 Blackout cartridges.

🧩 Barrel: The barrel is a key component that must be specifically chambered for 300 Blackout. The chamber dimensions are different from those of the standard 5.56 NATO/.223 Remington chamber, allowing for proper head spacing and extraction of 300 Blackout cartridges.

🧩 Gas System: The gas system in an AR-15 rifle can be utilized for 300 Blackouts. Different gas system lengths, such as pistol-length, carbine-length, or mid-length, are compatible depending on your specific build and preferences.

🧩 Handguards and Accessories: Handguards, rail systems, and other accessories designed for the AR-15 platform are generally compatible with 300 Blackout. These components provide customization options for attaching accessories such as optics, lights, foregrips, or lasers.

Conclusion😉

The best 300 Blackout upper is an essential part of any shooter’s arsenal. It offers excellent performance and accuracy, as well as versatility for different shooting applications. We hope this guide has provided you with all the information necessary to make a confident purchase decision when it comes time to buy your upper. Thanks for reading!😊💝

        I highly recommend the Ghost Firearms .300 Blackout Complete Upper Receiver. It has been proven to reliably shoot supersonic rounds. Additionally, when equipped with a suppressor that produces a normal amount of backpressure, it consistently cycles 200 to 220-grain subsonic rounds from various manufacturers.

          My personal favorite is the Radical Firearms .300 Blackout AR15 Upper Receiver.

            I’m currently in the market for an upper to complete my build, and my budget is under $1000. I’ve been searching for an upper all summer, but haven’t had any luck finding a quality. My main intention is to run both supersonic and subsonic ammunition, primarily while using a suppressor. However, I’d like to keep the total cost of the upper under $1000. Thank you for your assistance.

                I would highly recommend reconsidering the option of building your own upper or purchasing the necessary parts and having someone else assemble it for you. The barrels are on clearance for just $150, which is a great price. You can also find blemished upper receivers for around $70, offering excellent value. An adjustable gas block has one available for $65. To complete the build, a handguard for $80 would be a great choice. While a lightweight bolt carrier group (BCG) isn’t necessary, it can be very beneficial when paired with an adjustable gas block for tuning a 300 BLK gas system.

                  When it comes to finding the best 300 Blackout complete upper for my needs, ideally, I’m looking for a barrel length between 5.5 and 8 inches. Additionally, I already own a DB15 pistol, so I’m considering whether purchasing a complete upper or just the barrel and gas block would be the better option.

If you’re primarily engaging in hobby shooting or seeking a solid option for home defense, Aero Precision M4E1 Threaded Blackout Upper will serve you well. However, for military-grade durability, the Radian Weapons .300 Blackout Complete Upper Receiver offerings are truly top-tier.
