Radical Firearms AR-15 RF Upper Assembly 16in 7.62×39 w/ A2 Flash Hider Review

Let’s Talk About Radical Firearms AR-15 RF Upper Assembly 16in 7.62×39 w/ A2 Flash Hider

The Radical Firearms AR-15 RF Upper Assembly 16in 7.62×39 w/ A2 Flash Hider offers an entry point into the world of 7.62×39 AR-15 platforms without breaking the bank. Radical Firearms is known for providing budget-friendly AR components, and this upper assembly aims to bring the hard-hitting 7.62×39 cartridge to the familiar AR-15 platform. It features a 16-inch HBAR profile barrel, carbine-length gas system, and an A2 flash hider.

I’ve always been intrigued by the 7.62×39 cartridge in the AR platform. I wanted a more potent option than the standard 5.56 NATO, something that could deliver more energy downrange while still utilizing the AR’s modularity.

My first impression upon unboxing was surprisingly positive. The finish was clean, and the handguard felt solid enough, although not premium. I immediately appreciated the free-float rail system, knowing this would improve accuracy potential.

Compared to a higher-end Bravo Company upper I own and a budget Palmetto State Armory upper I previously used, the Radical Firearms offering felt somewhere in the middle. The BCM is clearly superior in fit and finish, while this Radical Firearms seems a step up from the PSA in terms of handguard design and perceived quality of the barrel. I ultimately chose it for the balance of price and features, hoping to get decent performance without a huge investment. I was excited to finally have a 7.62×39 AR upper that didn’t require me to sell my car!

Real-World Testing: Putting Radical Firearms AR-15 RF Upper Assembly 16in 7.62×39 w/ A2 Flash Hider to the Test

First Use Experience

I took the Radical Firearms upper to my local outdoor range. I mounted it on an Anderson Manufacturing lower receiver, paired with a CMMG 7.62×39 dedicated magazine and a Radical Firearms BCG. The weather was sunny, with a slight crosswind.

The first few magazines experienced some feeding issues. The rifle initially had failures to extract, which is a common problem when converting an AR-15 to 7.62×39. After about 50 rounds, the upper began to cycle more reliably.

Extended Use & Reliability

After a break-in period of roughly 200 rounds, the Radical Firearms upper has proven to be reasonably reliable. I’ve put approximately 500 rounds through it, including a mix of Tula, Wolf, and some brass-cased ammunition. There has been a significant decrease in failures to feed, but I still experience the occasional hiccup, especially with steel-cased ammo.

The finish on the upper receiver is showing some wear around the ejection port. The Melonite finish on the barrel seems to be holding up well. Cleaning is relatively straightforward, although the gas block can be a bit tricky to access. Compared to my 5.56 AR, the 7.62×39 variant requires more frequent cleaning due to the dirtier nature of the ammunition. It performs adequately, though a more expensive upper is likely to deliver superior reliability and durability.

Performance & Functionality

The Radical Firearms AR-15 RF Upper Assembly 16in 7.62×39 w/ A2 Flash Hider performs adequately for its price point. Accuracy is acceptable, I was able to achieve consistent 3-4 MOA groups with quality ammunition. The upper’s reliability is adequate after break-in, but it’s not flawless, and is more ammunition sensitive than a typical 5.56 AR.

The biggest strength is its affordability. Weaknesses include the occasional feeding issues and less-than-stellar fit and finish. It mostly meets expectations, providing a functional and relatively inexpensive entry into the 7.62×39 AR world.

Design & Ergonomics

The build quality is acceptable, but not outstanding. The materials used appear to be of decent quality, but the fit and finish could be better. The handguard is functional but feels somewhat flimsy.

The M-LOK rail system provides ample space for accessories. The A2 flash hider does a decent job of reducing muzzle flash, but there are better options available. The upper is generally user-friendly, with no significant learning curve for experienced AR-15 users.

Durability & Maintenance

I expect this upper to last for several thousand rounds with proper maintenance. The Melonite finish should help protect the barrel from corrosion. Cleaning is straightforward, but more frequent cleaning is required compared to a 5.56 AR due to the dirtier ammunition.

Accessories and Customization Options

The upper assembly comes with an A2 flash hider. The M-LOK handguard is compatible with a wide variety of accessories. You could add aftermarket optics, grips, lights, and lasers.
The 5/8×24 thread pitch allows for the use of various muzzle devices, including muzzle brakes and suppressors.
