Two popular choices for enthusiasts seeking more power and versatility are the 450 Bushmaster and 50 Beowulf AR uppers. In this article, we will delve into the features, benefits, and differences between these two powerhouse AR upper receivers. 

The 450 Bushmaster Upper: 

The 450 Bushmaster upper is a favorite among hunters and sports shooters who need a hard-hitting, high-caliber solution for their AR-15. Developed by Hornady Manufacturing in collaboration with Bushmaster Firearms, this cartridge is designed to provide maximum stopping power at shorter ranges. 

Key Features of the 450 Bushmaster Upper: 

1. Caliber: The 450 Bushmaster upper boasts a .45 caliber projectile, offering a significant increase in stopping power compared to the standard 5.56mm NATO round. 

2. Stopping Power: It is specifically designed for taking down big game at close to medium ranges, making it an ideal choice for hunting large game like deer and hogs. 

3. Reliable Feeding: The upper is engineered to ensure reliable feeding and ejection, minimizing the risk of jams or misfires during critical moments. 

4. Versatility: The 450 Bushmaster can be easily adapted to fit your AR-15 lower receiver, making it a versatile option for those looking to upgrade their existing platform. 

The 50 Beowulf AR Upper: 

On the other hand, the 50 Beowulf AR upper is another formidable choice that has gained popularity for its immense power and reliability. 

Key Features of the 50 Beowulf AR Upper: 

1. Caliber: The 50 Beowulf upper uses a .50 caliber projectile, making it one of the most powerful options available for the AR-15 platform. 

2. Stopping Power: With a larger caliber, the 50 Beowulf upper is capable of delivering devastating stopping power, making it ideal for hunting and home defense. 

3. Compatibility: Just like the 450 Bushmaster, the 50 Beowulf upper can be easily paired with your AR-15 lower receiver, ensuring compatibility with your existing firearm. 

Comparison: 

When comparing the 450 Bushmaster and 50 Beowulf AR uppers, several factors should be considered: 

1. Stopping Power: The 50 Beowulf undoubtedly takes the lead in terms of sheer stopping power due to its larger caliber. 

2. Ammunition Availability: While both calibers are readily available, the 450 Bushmaster may have a slight advantage in terms of ammunition variety and affordability. 

3. Effective Range: The 450 Bushmaster is generally considered more suitable for medium-range engagements, while the 50 Beowulf excels at close-quarters combat. 

4. Recoil: The 450 Bushmaster typically generates less recoil compared to the 50 Beowulf, which can be a significant factor for shooters who prioritize quick follow-up shots. 

Conclusion: 

In summary, choosing between the 450 Bushmaster and 50 Beowulf AR uppers ultimately depends on your specific needs and preferences. If you require maximum stopping power and are willing to manage higher recoil, the 50 Beowulf is the way to go. On the other hand, if you need a versatile, hard-hitting caliber with manageable recoil, the 450 Bushmaster is an excellent choice.
