    Just a warning the flash hider is not the one pictured above it is stainless as well…. and mine is about a 1/4 turn from being straight with the gun and wont turn on or off… also whoever did the deburr job on it sucked. Looks like a beaver chewed on the flash hider… other then that very happy money well spent

    Received my upper within a week, it’s a custom build with the 15″ key mod rail on the 16″ barrel and the Barrett style muzzle brake. Customer service was great! Definitely going to purchase another product soon!

    When I opened the package I was elated about the looks and fit. It was nothing till I have assembled the rifle and went to the range. It is advertised 1″ groups. Well let me tell you 6 different loads and 3 out of them close to .5″. It doesn’t like 40 gr bullets but as to be expected with the barrel twist. All load I had at home from previous hunting trips. The next pleasant surprise was when I cleaned the barrel it was a breeze. What a great product. Recommend not to look for anybody else’s offer, this one is a steel.

    I really liked how the gun shot. This is my second build. The first came from another company. This one out preformed the first one hands down. I was very pleased with the shot grouping. Look forward to trying another one soon. The only problem I had was the rail system did not line up correctly with my scope mount. I made a slight adjustment and it worked fine.
