5 of 5 Quite nice quality March 9, 2020
Reviewer: Seth Woods from Killeen, TX United States  
Very good quality. Though this is sudden and have not had a lot of range time, I can say that I have put approximately 600 rounds through my upper I ordered. Not one failure, not one stoppage, I ran a lot of different rounds with a lot of different weights. Everything still ran flawlessly.  
On a side note, their customer service is quite good as well... that being said, I'm still waiting on my shirt they promised me... even going as far as to ask my shirt size

Reviewer: John King from Mount Vernon, KY United States  
Excellent product at a great price. Fast shipping. Been running this upper with a Vltor A5 system, runs like a scalded dog! Very high quality for the money.
