5 of 5 Well built upper December 28, 2022
: Colby Kerns from Wichita Falls, TX United States  
I love the upper. The look and the feel of it are great. Couldn’t be happier. When I put it on my lower if fires fine but for some reason it’s not picking up the next round and chambering it. I’m sure it’s just a gas issue, so not MAS fault. Great upper for a great price

5 of 5 Great quality January 2, 2022
: Joseph Hubka from IL United States  
I love the look and feel of this hand guard and flash can setup. I am waiting on a brace to come in so I can take it to the range, but from my initial inspection, it is a solid upper with a quality finish. Everything is tightened to spec and put together properly.
