First Impressions of Moriarti AR-15 16 inch 5.56 Nato Upper Receiver Assembly
The AR-15 platform is ubiquitous, and the market is flooded with options, from complete rifles to individual components. The Moriarti AR-15 16 inch 5.56 Nato Upper Receiver Assembly aims to provide a budget-friendly, ready-to-go solution for builders or those looking to upgrade their existing setup. Moriarti Armaments promises a quality upper receiver assembly without breaking the bank, featuring a 16-inch barrel, M-LOK handguard, and a triport muzzle brake.
I needed a reliable and accurate upper receiver for a build focused on recreational target shooting and the occasional varmint hunt. I was looking for something that offered good value without sacrificing too much in terms of quality and features.
My initial impression of the upper was positive, given the price point. The finish appeared consistent, and the 15-inch M-LOK handguard felt solid in hand. It had a decent weight.
Compared to similar offerings from Palmetto State Armory and Aero Precision, the Moriarti upper seemed to offer comparable features at a slightly lower price. I chose it because of the aggressive styling of the triport muzzle brake and the promise of decent accuracy from the 4150 CMV steel barrel. My expectations were cautiously optimistic, hoping for a reliable and accurate upper that wouldn’t require immediate upgrades.
Real-World Testing: Putting Moriarti AR-15 16 inch 5.56 Nato Upper Receiver Assembly to the Test
First Use Experience
I tested the Moriarti AR-15 16 inch 5.56 Nato Upper Receiver Assembly at my local outdoor range, which features distances out to 200 yards. The weather was sunny and dry, around 70 degrees Fahrenheit, perfect for shooting. I mounted the upper on a standard AR-15 lower receiver with a milspec trigger and used a variety of 5.56 NATO ammunition, ranging from 55-grain FMJ to 62-grain green tips.
The upper functioned flawlessly out of the box. The carbine-length gas system seemed properly tuned, and I experienced no malfunctions in the first 100 rounds. No issues or surprises after first-time use.
Extended Use & Reliability
After several range trips and approximately 500 rounds fired, the Moriarti upper has proven to be quite reliable. There are no signs of excessive wear and tear. I’ve noticed some minor discoloration on the muzzle brake, but that’s to be expected with use.
Cleaning the upper is straightforward. The hardcoat anodized finish wipes down easily, and the barrel is simple to clean with a standard cleaning rod and bore brush. It performs similarly to other budget-friendly uppers I’ve used, perhaps exceeding expectations slightly in terms of accuracy.
