Let’s Dive into Radical Firearms AR-15 Complete Upper Receiver 7.62×39 HBAR
The Radical Firearms AR-15 Complete Upper Receiver 7.62×39 HBAR offers a compelling solution for AR-15 enthusiasts seeking to chamber their platform in the potent 7.62x39mm cartridge. This complete upper receiver assembly, manufactured by Radical Firearms, promises a reliable and affordable upgrade, boasting features like a heavy-barrel (HBAR) profile, a free-float handguard, and compatibility with M-LOK accessories. Its aim is to provide shooters with enhanced accuracy and versatility, all while keeping the cost manageable.
I needed a dedicated upper receiver for a hog hunting build. I was looking specifically for a 7.62×39 option, as the caliber has proven effective in short to medium range engagements on tough game.
Upon unboxing, the Radical Firearms upper felt solid, although not exceptionally refined. The melonite finish appeared durable, and the handguard felt comfortable in hand.
I was considering a similar upper from Bear Creek Arsenal and a higher-end option from CMMG. Ultimately, the Radical Firearms offering struck a balance between price and features, with the promise of improved accuracy from the HBAR barrel.
My initial impression was cautiously optimistic. The upper seemed well-assembled and ready to install, but I reserved judgment until I could get it to the range and put some rounds downrange.
Real-World Testing: Putting Radical Firearms AR-15 Complete Upper Receiver 7.62×39 HBAR to the Test
First Use Experience
My initial testing occurred at my local outdoor range. The weather was clear and relatively mild, providing ideal conditions for accuracy testing.
The Radical Firearms upper was paired with an Anderson Manufacturing lower receiver and a variety of 7.62×39 ammunition, including steel-cased and brass-cased options. The upper cycled reliably for the most part, but I did experience a few failure-to-eject malfunctions within the first 50 rounds.
The upper was easy to install and get running, although as previously noted there were malfunctions initially. I found the handguard comfortable to grip, and the A2 flash hider did a decent job of mitigating muzzle flash.
Extended Use & Reliability
After approximately 500 rounds, the Radical Firearms AR-15 Complete Upper Receiver 7.62×39 HBAR has proven to be generally reliable, with the initial ejection issues largely resolving themselves after the break-in period. I attribute the initial malfunctions to tight tolerances and the nature of steel-cased ammunition.
The melonite finish has held up well to regular use, showing only minor signs of wear on high-contact areas. I have not experienced any significant issues with durability.
Cleaning and maintenance are straightforward. The melonite finish is easy to wipe down, and the bolt carrier group disassembles easily for thorough cleaning.
Compared to a previous 5.56 upper receiver I owned, the Radical Firearms offering delivers noticeably improved accuracy at medium ranges due to the HBAR profile. However, the 7.62×39 cartridge exhibits more recoil than 5.56.
