5 of 5 Excellent quality, great price April 20, 2023
: Aaron W  
The fit and finish is as good as any upper I’ve handled. Fits tight to a couple different lowers. Shipped incredibly fast as well. I am very pleased!

5 of 5 13.7" 556 upper March 24, 2023
: Anthony Taylor from Benton, KY United States  
For the price I was not expecting very much but I was very surprised by the quality of the fit and finish. Fit and finish is on par with some of my other uppers costing double the price.  At the time of the review, I have ony shot 160 rounds through it. I didn't have any malfunctions at all and accuracy was good.  Shipping was fast I received my order in 4 days.

5 of 5 Complete upper September 7, 2022
: Rem R from Anchorage, AK United States  
I was doing a budget build and found Masdefense.
I must say, the upper came in fast. Recently did a mag dump of 300 rounds of 556 and 223 and not a single malfunction. However, there was a gas leak on the block. Inspected and found no deficiencies. I placed it back and torqued it down. No more leak. Overall, very nice product for a reasonable price
