I have to say, that I am very impressed with the accuracy that this upper has produced! Averaging 1 1/4” groups @100 yards consistently. I did replace the APF factory M-Loc forend and Muzzle Device. ( more for a personal touch than anything.) The recoil was less than expected with the factory Brake! This little “Sledgehammer” is Definitely worth every penny! I still hve a huge smile on my face!
