5 of 5 Glad I found this April 8, 2020
: Murlin Green from Gaylord, MI United States  
I picked the worst time possible to buy, middle of coronavirus buying spree. Places I knew of were gutted. I knew exactly the barrel length and twist rate I wanted and my search finally landed me here. I wanted fde color but I ordered it anyway with intention to cerakote it. Knowing this I should have ordered parts instead of a complete upper. I reached out to Mas Defense via email the next day to see if I could get the upper sent disassembled, and Mario the owner answered right away. He said he would try but couldn't promise. The order was probably already being processed, I got it in 4 days, which I thought was incredible given the current madness. It was not disassembled, but this thing is so beautiful I am inclined to change my build and stick with black receiver and put fde hardware on it. Excellent customer service response, beautiful product. I just got it today, haven't fired it, but based on first impressions I wouldn't hesitate to recommend Mas Defense. I will come back.
