First Use Experience
I first tested the OpticsPlanet Exclusive Moriarti AR-15 10.5in 5.56x45mm NATO Upper Receiver Assembly, A2 Flash Hider at my local outdoor shooting range.

Performance was surprisingly good, even with inexpensive brass ammunition. The upper cycled reliably and consistently ejected spent casings with good force, indicating proper gas system function. There were no initial failures to feed or extract, and the A2 flash hider effectively mitigated muzzle flash, especially noticeable in the shorter barrel.
Ease of use was excellent; the upper receiver required no modification to fit my lower, and the charging handle was smooth. I experienced no issues with mounting accessories on the M-LOK handguard either. After a quick sight-in, I was consistently hitting targets at 50 yards, confirming acceptable accuracy for my intended purposes.

Minor cleaning and lubrication are necessary after each range trip, as is typical with AR-15 platforms.
Durability has also been impressive. The Cerakote finish has held up well to handling and transport, showing minimal signs of wear. The free-float handguard remains solid and secure, even after repeated accessory attachments and removals.
Maintenance is straightforward; a standard AR-15 cleaning kit is sufficient for keeping the upper receiver in good working order. Compared to my previous experiences with budget-friendly AR-15 uppers, the Moriarti has surpassed my expectations in terms of reliability and durability, making it a worthwhile investment.
