Real-World Testing: Putting Moriarti Moriarti 5.45×39 AR Theraded Barrel to the Test

First Use Experience

I tested the Moriarti Moriarti 5.45×39 AR Theraded Barrel at my local outdoor shooting range. The weather was slightly overcast, but the temperature was comfortable.

The Moriarti barrel performed admirably. I was particularly interested in evaluating its accuracy and reliability with different types of 5.45×39 ammunition.

I didn’t experience any major issues during the first range session, although I did notice that the gas port seemed slightly over-gassed, causing slightly more felt recoil than anticipated for a 5.45×39 build. This was easily managed with an adjustable gas block I had on hand.

Extended Use & Reliability

After several months of consistent use, the Moriarti Moriarti 5.45×39 AR Theraded Barrel has proven to be a reliable performer. I have put approximately 500 rounds through it without any malfunctions directly attributable to the barrel itself.

The matte black finish has held up well, with only minor signs of wear around the muzzle. Cleaning the barrel is straightforward, and I have not observed any significant issues with corrosion or fouling.

Compared to my experience with higher-end barrels, the Moriarti barrel is not quite as accurate, but it is perfectly adequate for recreational shooting and plinking. It does exactly what I expect it to, and I appreciate that reliability.
