Introduction 

The AR-15 platform is renowned for its versatility, allowing firearm enthusiasts to customize their rifles to meet various needs and preferences. Two popular upper assembly options for AR-15 enthusiasts are the 350 Legend upper and the 300 Blackout upper. In this article, we'll delve into the specifics of these two uppers and explore their unique features, helping you make an informed decision when choosing the perfect upper assembly for your AR-15 rifle. 

350 Legend Upper Assembly 

The 350 Legend upper assembly is gaining popularity among AR-15 enthusiasts due to its unique characteristics. One of the standout features of the 350 Legend is its impressive range and power. Designed for hunting, this upper assembly delivers substantial energy, making it ideal for taking down medium-sized game animals. 

The upper assembly we're discussing here, found at moriartiarmaments.com, boasts a 20-inch stainless steel barrel and a quad rail handguard. This setup offers excellent accuracy and durability. Stainless steel is known for its corrosion resistance, ensuring that your upper assembly will stand the test of time. The quad rail handguard provides ample space for mounting accessories like optics, lights, and grips, allowing for customization to suit your specific needs. 

300 Blackout Upper Assembly 

The 300 Blackout upper assembly is another compelling option for AR-15 enthusiasts. It's renowned for its versatility and adaptability. One of its most significant advantages is its compatibility with standard AR-15 lower receivers. This means you can easily convert your existing AR-15 into a 300 Blackout rifle by simply swapping the upper assembly. 

The 300blk upper assembly found at moriartiarmaments.com features a 16-inch barrel, making it more compact than the 350 Legend option. The shorter barrel is beneficial for close quarters shooting and manoeuvrability. Like the 350 Legend upper, this assembly also includes a quad rail handguard for accessory customization. 

Comparison 

Let's break down the key differences between these two upper assemblies: 

1. Caliber: The 350 Legend upper assembly fires .350 caliber rounds, which are excellent for hunting due to their impressive energy and stopping power. On the other hand, the 300 Blackout upper assembly fires .30 caliber rounds, which are known for their versatility and adaptability.
2. Barrel Length: The 350 Legend upper assembly features a longer 20-inch barrel, while the 300 Blackout upper assembly has a more compact 16-inch barrel.
3. Use Cases: The 350 Legend is ideal for hunting, thanks to its long-range capabilities, while the 300 Blackout excels in both close quarters combat and suppressed shooting.

Conclusion 

In summary, both the 350 Legend and 300 Blackout upper assemblies have their unique strengths and applications. The 350 Legend upper assembly is perfect for hunters seeking long-range accuracy and power, while the 300 Blackout upper assembly is versatile, compatible with existing AR-15 lowers, and suitable for various scenarios.
