Ordered this upper for pistol build
Works flawlessly, no complaints, will buy from Moriarti arms again

Just recently bought this upper. It worked flawlessly. I throw a bunch of different quality ammo thru it to see what it didn’t like to shoot. This upper shot it all. Didn’t have a misfeeds or a jam after 300rds. Very happy with it. Would buy from here again with no second thought.

My 10.5" Socom 300 Blackout arrived quickly, excellent quality build, will be ordering more items from your cool store, thank you

Fairly impressed with the the quality and price.

The coolest upper I've had! Love the look and how it performs. Everything fit together well and mated well with the lower I had purchased, never had a misfire or jam. Put about 400 rounds through it so far!
