9 Things to Know Before Upgrading to a 300 Blackout Upper

Upgrading your firearm can be a significant decision, particularly when it involves switching to a new caliber like the .300 Blackout. This cartridge, known for its versatility and effectiveness in various shooting scenarios, has gained popularity among both hunters and tactical shooters. Before making the leap, here are nine essential things you should know.

1. Understanding the .300 Blackout Cartridge

The .300 Blackout (7.62x35mm) was developed for the U.S. military to provide the ability to use both subsonic and supersonic ammunition from the same platform. It offers a powerful performance in a compact package, making it ideal for tactical applications and hunting. Knowing how this cartridge operates differently from others is crucial for shooters considering an upgrade.

2. Compatibility with Existing Platforms

One of the major advantages of the p80 glock is its compatibility with standard AR-15 lower receivers and magazines. This means that if you already own an AR-15, you can easily swap out your upper receiver for a .300 Blackout upper. However, it’s essential to ensure that your lower has a suitable barrel extension for optimum performance.

3. Amp Up Your Suppressor Game

If you plan on using subsonic rounds for stealth shooting, a suppressor can drastically reduce the noise. The .300 Blackout was specifically designed to work well with suppressors, allowing you to take full advantage of its capabilities. Consider investing in a quality suppressor if you plan on using the subsonic ammo frequently.

4. Choose the Right Barrel Length

Barrel length can have a significant impact on the performance of the .300 Blackout. Generally, you can choose between 8 to 16 inches, but shorter barrels excel with subsonic rounds, while longer barrels perform better with supersonic ammunition. Think about your intended use—hunting, home defense, or tactical might influence your choice of barrel length.

5. Ammunition Availability and Cost

While the .300 Blackout has become increasingly popular, it can still be harder to find than mainstream options like the 5.56 NATO. When considering an upgrade, assess the availability of ammunition in your area and factor in the cost—both for practice and self-defense rounds. Prices can vary, so make sure to shop around.

6. Consider Ballistics and Performance

The .300 Blackout offers impressive ballistics, especially at shorter distances. Its heavy bullets (typically 110 to 220 grains) provide excellent stopping power against game animals and can perform exceptionally well at close range. However, they may lose effectiveness at longer ranges, so consider your shooting scenarios when making the switch.

7. Adapt Your Optics

When upgrading to a .300 Blackout upper, re-evaluating your optics is also beneficial. Given that bullet drop can vary significantly between subsonic and supersonic rounds, having an optic that allows for quick adjustments can be crucial for accuracy. Consider investing in adjustable scopes or red dots that accommodate both round types.

8. Learn the New Reloading Data

For those who enjoy reloading, familiarize yourself with the specific loading data for the .300 Blackout. Both subsonic and supersonic rounds require unique considerations concerning bullet type, powder selection, and loading techniques. Acquire reloading manuals focused on the .300 Blackout to ensure you’re following safe and effective practices.

9. Training and Familiarization

Finally, once you’ve upgraded to a .300 Blackout upper, investing in training and practice is essential. The recoil, ballistics, and overall handling can differ significantly from what you’re accustomed to. Regular practice will help you become proficient with your new setup, ensuring you can take full advantage of its capabilities when it counts.

Conclusion

Upgrading to a .300 Blackout upper can be a rewarding decision for any firearm enthusiast. By understanding its features, compatibility, and the necessary adjustments to your setup, you can maximize the benefits this versatile cartridge has to offer. Remember, whether for hunting or tactical applications, knowledge and preparation are key to making the most of your investment.
