As a long time AR 15 enthusiast, I have come across many muzzle devices. Some hardly change the dynamics of the rifle recoil or muzzle control. Others provide so much improvement it changes your second shot accuracy dramically, while still others actually create more of a problem. So what do you do? With most “name brand muzzle devices costing over $100, most cannot afford to do trial and error. So we did it for you. This video is part 1 of a 3 part series where we will test these devices. Future videos will add new devices. In this video, we are ONLY looking at muzzle movement on a horizontal plane. In other words, muzzle rise or muzzle dip. The results are obvious. We actually stopped carrying one of these as a result of this test while we now recommend two others for the same reason.
