Matador mat-9k - Matador Arms Mat-9K 5 inch 9mm Upper Reciever

Well it a nice upper took it to the range shot 2 rounds . The “ez-take down” piece broke” matador has life time warranty so called them an sent me a new one still waiting for it to arrive . I could’ve sent it back an waited for a replacement from optics planet .. the 2 shots I did get to enjoy was nice . I built a 9mm lower from Andro rave 140 trigger . Pairs nicely together super tight fit . If not for breaking I feel 5 stars would be in order.. I suggested to matador that they make those parts in steel or aluminum. They said maybe an air bubble in the part that’s why it may have broke . My suggestion is if you do buy this buy a back up kit for 35.00 . They said in the future those peices in metal maybe available on the site. Only time will tell . Maybe I’ll do another review when it comes in .
