Real-World Testing: Putting OpticsPlanet Exclusive Moriarti AR-15 10.5in 300 Blackout Upper Receiver, Triport to the Test
First Use Experience
My initial range trip with the OpticsPlanet Exclusive Moriarti AR-15 10.5in 300 Blackout Upper Receiver, Triport was at an outdoor range known for its varied distances and challenging wind conditions. I primarily used it with a mix of supersonic and subsonic 300 Blackout ammunition. The upper cycled reliably from the first round, showing no initial signs of gas system issues.
I found the 10.5-inch barrel surprisingly easy to handle. The Triport muzzle brake noticeably reduced felt recoil, allowing for faster follow-up shots. It took me a few magazines to dial in my optic for the 300 Blackout trajectory, but once zeroed, I was consistently hitting targets at 50 and 100 yards.
Extended Use & Reliability
After several months and hundreds of rounds, the OpticsPlanet Exclusive Moriarti AR-15 10.5in 300 Blackout Upper Receiver, Triport has proven to be reliable. I’ve experienced no failures to feed or extract. The anodized finish has held up well, showing minimal wear despite regular use and transport.
Cleaning the upper is straightforward, with easy access to the bolt carrier group and barrel. Regular lubrication has kept it running smoothly. Comparing it to a previous 16-inch 5.56 upper, the Moriarti 300 Blackout excels in close-quarters maneuverability and subsonic performance, but sacrifices some long-range accuracy.
