Rock River Arms ATH V2 .223 Wylde Upper Review

Out of the Box: Rock River Arms ATH V2 .223 Wylde Completed Upper

The Rock River Arms ATH V2 .223 Wylde Completed Upper promises enhanced accuracy and reliability for AR-15 enthusiasts. This complete upper receiver assembly boasts an 18-inch heavy barrel chambered in .223 Wylde, designed to handle both .223 Remington and 5.56 NATO ammunition with improved precision. The free-float handguard with M-LOK attachment points offers ample space for accessories, while the Rock River Arms Operator muzzle brake aims to mitigate recoil and muzzle rise.

I’ve been chasing the elusive goal of sub-MOA accuracy from a readily available AR-15 platform for years. My aging upper receiver on my go-to AR just wasn’t cutting it anymore, so I started researching completed uppers hoping to drop in and improve the accuracy and reliability of my AR significantly. The Rock River Arms ATH V2 .223 Wylde Completed Upper seemed like a strong contender.

Upon unboxing, the immediate impression was one of quality. The finish was flawless, the weight felt substantial without being unwieldy, and the handguard felt rock-solid. The fit and finish exuded a sense of precision.

I considered similar uppers from Bravo Company Manufacturing (BCM) and Daniel Defense, both renowned for their quality. However, the Rock River Arms upper offered a better combination of features and price for my needs. The .223 Wylde chamber and the included muzzle brake were key differentiators that swayed me.

My initial excitement was high. The build quality and features suggested this upper could be a significant upgrade. I was eager to see if it lived up to the promise of enhanced accuracy and consistent performance.

Real-World Testing: Putting Rock River Arms ATH V2 .223 Wylde Completed Upper to the Test

First Use Experience

The Rock River Arms ATH V2 .223 Wylde Completed Upper first saw action at my local outdoor range, a 100-yard facility with covered shooting benches.

The upper performed flawlessly. I experienced no malfunctions or failures to feed. The included RRA Operator muzzle brake noticeably reduced recoil, allowing for quicker follow-up shots.

It took very little time to get used to the new upper. The ergonomics were excellent, and the controls were intuitive. The only initial adjustment was getting used to the slightly heavier barrel profile compared to my previous upper.

There are no significant signs of wear and tear. The anodized finish has held up well, even after repeated use in various conditions. Regular cleaning and lubrication have been sufficient to maintain its performance.
