Guntec 9mm ar15 upper is outstanding - Guntec USA AR-15 9mm Dedicated Billet Upper Receiver

Didn’t really know what to expect when I ordered this upper. The price seemed a little too low to be much. I was very pleasantly surprised when I received the order. This upper is exceptionally well made. Rock solid billet aluminum. The milling is first class, and the finish is perfect..... perfect! Fit on my Spikes lower like it was made for it. I will absolutely use a Guntec on my next build. Wish I would have given them a look three ARs ago. I have since used their free float hand guard with similar results. These guys make high quality products for very reasonable prices. They have become my “go to” manufacturer for all things aluminum.
