Radical Firearms RF Upper Assembly 16in 300 AAC HBAR Contour w/ A2 Flash Hider Review

Let’s Talk About Radical Firearms RF Upper Assembly 16in 300 AAC HBAR Contour w/ A2 Flash Hider

The Radical Firearms RF Upper Assembly 16in 300 AAC HBAR Contour w/ A2 Flash Hider is an intriguing option for AR-15 enthusiasts looking to explore the versatility of the .300 AAC Blackout cartridge. Manufactured by Radical Firearms, this upper assembly boasts a 16-inch HBAR contour barrel, an A2 flash hider, and M-LOK compatibility. It promises a blend of accuracy, reliability, and adaptability, making it a potential game-changer for shooters seeking a suppressed or specialized AR platform.

My journey to this upper receiver started with a desire to build a dedicated home defense rifle. I wanted something compact yet capable of delivering significant stopping power. The .300 AAC Blackout’s subsonic capabilities when paired with a suppressor were particularly attractive.

Upon unboxing, the first thing that struck me was the solid feel of the assembly. The HBAR contour barrel gives it a substantial weight, inspiring confidence in its durability. The anodized finish appears clean and consistent, and the M-LOK handguard feels robust.

I was also considering a similar upper from Aero Precision, known for their tight tolerances, and a budget-friendly option from Palmetto State Armory. Ultimately, I chose the Radical Firearms upper because of its balance between price and features. The free-floating barrel and M-LOK handguard seemed like good value for the money.

My initial impression was cautiously optimistic. While the build quality seemed adequate, I was eager to see how it performed at the range. I had heard mixed reviews about Radical Firearms‘ quality control in the past, so I was hoping this upper assembly would exceed expectations.
