5 of 5 Awesome Upper December 10, 2022
: Dean from Odessa, FL United States  
High quality upper.  14.5" barrel gives great ballistics and accuracy downrange.  With this barrel length it may become my new vehicle weapon of choice.

5 of 5 Great parts/ great looking upper January 17, 2022
: Brian Pizarro from Chula Vista, CA United States  
I came across this site as I really like Aero products and the quality. I was surprised to find out they actually make the barrels for Aero, so it was a no brainer.
The owner even called me to tell he had put my parts request together and was being shipped the next day.
I really appreciated that as most places don’t really have any contact with the customer.
I have nothing but good things to say about this company. I will definitely be using them for any future build projects I have!

: from , Wisconsin  
I was hesitant at first so I did more research and found that many other reviews confirm Mas is a quality company with decent pricing. I would definitely buy more in the future.
