Moriarty ar-9 8.3" upper
Decided to give it a try. Delivery was quick. Completed the build and took it out the following Saturday. It ran 115,124,and 147grain flawlessly.
Most Helpful Negative Review
Feed Cone issues
Only got it to run seamlessly few times. I have gotten more FTF than anything. Will try to sand a polish the Cone of the feed ramp and update. Can not really recommend this upper at the moment. I know it was a cheaper upper so I knew what l was getting into. 3 stars for now
It didn't work out for me.
I swooped out the barrel it came with to a ballistic advantage advanced feed cone barrel, for reliable feeding of hollow points. If I was only using the AR9 for a rang rock breaker then this is a good option otherwise there's better options.
Would recommend: No
Questionable Quality Control
Overall the build quality feels pretty solid for the 200 dollar sale price point, however I would refrain from purchasing this upper at full price. I would also advise that you check the torque of your barrel nut, as mine was just hand tight and came loose during the first test fire. No damage was done to myself or the upper, but it did require me to run out to my shop to ensure it was all assembled properly.
Pros:
- utility
- Compact & light
- Budget minded
Cons:
- Questionable finish quality
- questionable build quality
Best Used for:
- range toy
Would recommend: Yes
