Understanding the 300 Blackout Cartridge
The 300 Blackout cartridge has revolutionized the AR-15 platform, offering a level of versatility and performance that has made it a favorite among shooters. Its ability to effectively chamber subsonic and supersonic loads has made it a popular choice for hunting, self-defense, and tactical applications. Integral to the success of the 300 Blackout is the magazine, the critical component that feeds ammunition into the firearm. This article provides a detailed overview of the 20 round 300 Blackout magazine, exploring its features, benefits, considerations, and the top choices available.
The 300 Blackout, also known as 300 BLK or 7.62x35mm, was developed by Advanced Armament Corporation (AAC) in partnership with Remington Defense. The goal was to create a cartridge capable of utilizing existing AR-15 platform parts (specifically, the bolt carrier group and magazine) while delivering superior performance compared to the standard 5.56x45mm NATO round, particularly in short-barreled rifles. The 300 Blackout achieves this by using a .30 caliber bullet loaded in a case shortened from the 5.56x45mm. This innovative design allows for the firing of heavier bullets, which provides enhanced stopping power and downrange energy.
One of the key benefits of the 300 Blackout is its versatility. It excels with both subsonic and supersonic loads. Subsonic loads offer suppressed shooting capabilities, as the bullet travels below the speed of sound, minimizing the sonic crack. Supersonic loads provide excellent ballistics for hunting and self-defense purposes, delivering significant energy on impact. This flexibility makes the 300 Blackout a great choice for various shooting scenarios. The cartridge’s performance in AR-15s and especially short-barreled rifles is also a major advantage. Due to the efficient powder burn, the 300 Blackout achieves its optimal performance with shorter barrels, making it ideal for compact platforms that are easy to maneuver and conceal.
Features and Benefits of 20 Round 300 Blackout Magazines
The magazine is more than just a container for cartridges; it plays a critical role in the reliability and performance of a firearm. When using the 300 Blackout, the magazine selection must consider the features that will make it a reliable feeder to your firearm. While standard and larger capacity magazines are readily available, the 20 round 300 Blackout magazine offers unique benefits.
One significant advantage is improved maneuverability and handling. A shorter magazine, especially when loaded, reduces the overall profile of the firearm, which is advantageous in confined spaces or during close-quarters combat. The shorter profile also reduces the risk of the magazine snagging on clothing or other objects. A 20 round magazine is typically easier to handle and manipulate compared to longer magazines. This is important during reloads, clearing malfunctions, or any situation where quick handling is crucial.
Another key advantage is the potential for improved concealment. A 20 round 300 Blackout magazine can be easier to conceal under clothing, making it a better choice for concealed carry or when discretion is a priority.
Considering the materials that create the magazine can greatly affect its performance in many areas. Two common materials for magazine construction are polymer and metal, such as aluminum or steel. Polymer magazines are generally lighter than metal magazines, and may be more resistant to dents. They can also be manufactured to include features such as witness windows, or markings for the number of rounds left in the magazine. Metal magazines, on the other hand, are often known for their strength, and potential longevity. The choice between polymer and metal often comes down to personal preference, desired features, and budget.
The construction design has a direct effect on the magazine’s reliability and functionality. A good follower design is essential for consistent feeding. Anti-tilt followers help prevent the rounds from binding within the magazine, ensuring smooth and reliable feeding of each round into the chamber. Self-lubricating followers reduce friction and further enhance feeding reliability. The feed lips must be correctly designed to properly hold the cartridges and consistently release them into the chamber. Well-designed feed lips are crucial to prevent jams and ensure a smooth feed cycle. The base plate design matters for easy disassembly, which simplifies cleaning and maintenance. Some base plates offer additional protection against drops and impacts. Round count windows are a handy feature, allowing shooters to quickly and easily see how many rounds are left in the magazine without having to remove it.
Factors to Consider When Choosing a 20 Round 300 Blackout Magazine
The selection of a magazine is an important decision, which can affect the reliability of your firearm. Several factors should be considered when selecting a 20 round 300 Blackout magazine.
Compatibility with your firearm is the first and most important factor. Ensure the magazine is specifically designed to work with your AR-15 platform and chambered in the 300 Blackout. Check for proper fit in the magwell. The magazine should insert and lock securely without any excessive play or wobble. The correct fit is crucial for proper feeding and reliable operation.
Reliability is paramount. The magazine should feed rounds smoothly and consistently without causing malfunctions. Look for magazines from reputable manufacturers with a proven track record for reliability. Read reviews from other users to gain insights into their experiences. Function testing is useful to ensure the magazine feeds properly.
The materials and construction have a direct impact on the magazine’s durability. Choose magazines made from high-quality materials that can withstand the rigors of use. Consider how the magazine will hold up in the environmental conditions you’ll be operating in. Magazines exposed to extreme temperatures, moisture, or harsh environments require more robust construction.
The price and value should be considered. Compare the price of different 20 round 300 Blackout magazines, but don’t automatically choose the cheapest option. Look for magazines that offer a good balance of quality, features, and cost. Consider what features you need and determine how much you are willing to spend.
Proper Magazine Care and Maintenance
Caring for your magazines will extend their life and ensure reliable functionality. Regular cleaning and maintenance are essential.
When cleaning your magazine, it should be disassembled following the manufacturer’s instructions. Clean the inside of the magazine body, the follower, and the spring. Avoid using harsh chemicals or abrasive materials that could damage the magazine.
A little lubrication is important. Lightly lubricate the follower and the spring to reduce friction and ensure smooth operation. Only use a small amount of a quality lubricant specifically designed for firearms.
Proper storage is crucial. Store magazines in a cool, dry place away from direct sunlight and extreme temperatures. Humidity can cause corrosion, so avoid storing magazines in damp environments. Inspecting the magazines from time to time is very important. Inspect your magazines regularly for any signs of damage, such as dents, cracks, or corrosion. Replace magazines if they are damaged or showing signs of wear that could affect their function.
Conclusion
The 20 round 300 Blackout magazine is an invaluable accessory for any owner of a 300 Blackout firearm. These magazines offer increased maneuverability, improved concealment, and a balance of performance and practicality. Selecting the right magazine, considering factors like compatibility, reliability, materials, and cost, is critical. Proper care and maintenance will ensure that your magazines function reliably for years to come. Consider your specific needs, and choose a 20-round magazine that offers the best combination of reliability, durability, and ease of handling for your 300 Blackout firearm.
